Description

Technical Field

[0001] The present invention generally relates to optical articles, and more particularly but not limited to optical articles for use with an eye wear device. Background Art

[0002] Optical articles (such as lenses) can be used to correct refractive errors of the eye, such as myopia, hyperopia, presbyopia, and astigmatism. When a user of an optical article (e.g., a prescription lens) wants to wear sunglasses, the user can use prescription sunglasses or wear contact lenses and use non-prescription sunglasses. Accordingly, the user must purchase multiple pairs of sunglasses.

[0003] Some conventional methods for providing greater flexibility to the user include providing a sunglass attachment for prescription eyewear products. Such a sunglass attachment is typically attached to the front of a prescription eyewear product using magnets or clips. However, when using magnets to couple the sunglass attachment, the manufacturing processes for making such an attachment and the corresponding prescription frame can be complex and expensive. When using clips to couple the sunglass attachment, such clips (or hooks) may be noticeable to others and, thus, may not be aesthetically appealing to the user. Another method is described in Korean Patent No. 20160140139, in which a film including a pair of lenses is attached to a pair of sunglasses using receiving grooves formed in the film, which are coupled to engagement grooves formed inside hinge protrusions of the sunglasses. However, the method of Korean Patent No. 20160140139 requires complex, specific, and specialized manufacturing processes, and the attachment mechanism (e.g., the receiving grooves) may be prone to damage.

[0004] Thus, users of prescription lenses who also use contact lenses can only choose from various sub-optimal products or spend money on both prescription and non-prescription eyewear products. Summary of the Invention

[0005] The present disclosure includes devices, systems, and methods associated with an optical article for use with an eye-wear device. For example, the optical article includes an optical member having opposite first and second lens surfaces. The optical member can be a full-back surface (FBS) lens or a bi-focal lens, by way of illustrative and non-limiting example. In some implementations, the optical member is a single optical member, such as a single prescription lens. The optical article also includes one or more attachment devices configured to removably couple the optical article to the eye-wear device, such as to a frame of the eye-wear device. The one or more attachment devices can include magnets, mounting brackets, or both, by way of illustrative and non-limiting example. The one or more attachment devices can be configured such that a user can position and / or align the optical article relative to one or more lenses of the eye-wear device, for example without the assistance of an optician. The user can selectively couple the optical article to the eye-wear device or decouple it from the eye-wear device as needed. For example, when a user is wearing contact lenses, the user can remove the optical article from the eye-wear device and wear the eye-wear device without the optical article. Alternatively, if the user is not wearing contact lenses, the user can couple the optical article to the eye-wear device and wear the eye-wear device with the optical article. Accordingly, the optical article provides versatility to the eye-wear device and / or makes the eye-wear device versatile, such that the user does not need to have both prescription and non-prescription forms of the eye-wear device, thereby reducing the cost to the user.

[0006] Additionally, the optical article can include or correspond to a prescription for a single eye, such that a user can have a first optical article for a first eye and a second optical article for a second eye. Correspondingly, the optical article enables management of different prescriptions such that the optical article can be replaced for a changing prescription of the eye. Further, in implementations where the optical article includes a single prescription lens, the weight of the optical article (or two optical articles) can be less compared to a solution where a single optical article includes two prescription lenses coupled to the eye-wear device (such as described in Korean Patent No. 20160140139). Additionally, compared to the optical article of Korean Patent No. 20160140139, which requires a specific, specialized manufacturing process, the optical article of the present disclosure can be produced using standard lens processes (e.g., molding, casting, surface finishing), thereby simplifying manufacturing and reducing manufacturing cost and time.

[0007] An eye-wear device can be configured for use with the optical articles described herein. For example, the eye-wear device can include one or more attachment devices for coupling with one or more attachment devices of the optical article. By way of illustration, the eye-wear device can include magnets (positioned in the temple region of the frame), notches (positioned on the nose pad and / or the frame), or a combination thereof, as illustrative but non-limiting examples. Accordingly, the one or more attachment devices of the eye-wear device can enable a user to securely and selectively configure the eye-wear device as a prescription eye-wear device or a non-prescription eye-wear device.

[0008] In some implementations, the optical article can include an optical component (e.g., a lens) and a support structure. For example, the support structure (such as an annulus) can be coupled to the optical component and can include or be coupled to one or more attachment devices. By way of illustration, at least a portion of the support structure can be positioned within a channel of the optical component, and the one or more attachment devices can be coupled to the optical component via the support structure. The support structure can be used to couple the optical component to the eye-wear device and can allow the optical component to be used with a wide range of prescriptions. For example, for a highly negative prescription, the radius of the lens (e.g., the optical component) is small, and the distance between the lens and the eye is small. As a result, the eyelashes may potentially touch the prescription lens. Using the support structure allows the use of a highly negative prescription lens (e.g., the optical component) by increasing the width between the inner surface and the outer surface of the support structure. Alternatively, the support structure can be designed to couple a highly positive prescription lens to the eye-wear device without the optical component interfering with the lens of the eye-wear device or the wearer's eyelashes. In other words, the support structure (or the exposed portion of the support structure when coupled to the optical component) can be customized based on the prescription of the optical component and the frame of the eye-wear device. Additionally, the support structure allows for the easy replacement of a cracked or damaged lens (e.g., the optical component). The user can attach or remove the support structure to easily replace the optical component without the need for professional services provided by, for example, an optician, an ophthalmologist, an optometrist, etc. Additionally or alternatively, different support structures can be coupled to the optical component in order to use the optical component with different eye-wear devices.

[0009] In some implementations, an optical article includes: a first portion 312 that includes a first portion (e.g., a lens portion); and a second portion (e.g., an extension portion) that extends from a side surface of the first portion. The extension portion can define a flange formed by at least one side surface of the optical article. The flange can enable a small gap to exist between a first surface (e.g., a front surface) of the optical member and a lens of an eyewear device. Compared to an eyewear device without the optical article 300, such positioning can make the use of the optical article 300 less noticeable. Additionally or alternatively, compared to the optical article 200, the optical article 300 includes an overall design that reduces the number of components, which can be fabricated faster, reduce costs, and can have more stringent tolerance control, thereby providing a secure fit between the optical article 300 and the frame. Additionally, compared to an eyewear device without an optical article, the small gap can make the use of the optical article less noticeable.

[0010] In one aspect of the present disclosure, a device (e.g., an optical article) for use with an eyewear device includes a single optical member having opposite first and second lens surfaces. The optical article can further include a magnet coupled to the optical member and configured to be coupled to a frame of the eyewear device. The optical article can also include a mounting bracket coupled to the optical member and configured to be coupled to a frame of the eyewear device.

[0011] In some implementations of the foregoing device, the optical article further includes a support structure coupled to the optical member. The optical member can be coupled to the magnet via the support structure, and the mounting bracket can be coupled to or integral with the support structure, or have both the magnet and the mounting bracket.

[0012] In some implementations of the foregoing device, the optical member includes a channel formed via a side surface of the optical member. The side surface can be positioned between the first and second lens surfaces. In some such implementations, at least a portion of the support structure is positioned within the channel. The size, shape, or both of the support structure can be based on one or more features of a frame of the eyewear device. In some implementations, the support structure can include an annular structure, at least a portion of which is positioned within the channel of the optical member. Additionally or alternatively, the magnet, the mounting bracket, or both can be coupled to or in contact with the support structure.

[0013] In some implementations of the foregoing device, the optical member includes a first portion and a second portion. The first portion may include a lens that includes a first lens surface and a second lens surface. Additionally or alternatively, the second portion may extend from a side surface of the first portion. The side surface may be positioned between the first lens surface and the second lens surface. In some implementations, the second portion is coupled to a magnet and is coupled to or includes a mounting bracket.

[0014] In some implementations of the foregoing device, the optical member includes a prescription lens. In some such implementations, the optical member is configured to be coupled to the user-facing side of a frame using a magnet and a mounting bracket. Additionally or alternatively, to couple the optical member to the frame, the magnet is configured to be positioned in a first cavity of the frame and at least a portion of the mounting bracket is configured to be positioned within a second cavity of the frame, or to do both.

[0015] In some implementations of the foregoing device, an eye-wear device is configured to be coupled to the optical member. In some such implementations, the eye-wear device may include a frame that has a first side and a second side. The second side may be the user-facing side. In some implementations, the frame includes: a nose pad that has a cavity configured to receive a mounting bracket arm of the optical member; a magnet coupled to the second side and configured to magnetically couple with the magnet of the optical member; or both. Additionally or alternatively, the eye-wear device may include one or more lenses coupled to the optical frame and each of the one or more lenses may be different from the optical member. The eye-wear device may include a device selected from the group consisting of: an eyewear product, an eyewear article, sunglasses, safety glasses, or goggles.

[0016] In another aspect of the present disclosure, a device (e.g., an eye-wear device) includes a frame that has a first side and a second side. The second side may be the user-facing side. The frame may define a cavity, include a magnet, or both, that is configured to receive a mounting bracket arm of the optical member, the magnet being coupled to the second side and configured to magnetically couple with the magnet of the optical member. In some implementations, the cavity is formed in the nose pad of the frame.

[0017] In some implementations of the foregoing device, the device (e.g., an eye-wear device) includes one or more lenses coupled to the optical frame. Each of the one or more lenses may be different from the optical member. In some such implementations, the eye-wear device is a device selected from the group consisting of: an eyewear product, an eyewear article, sunglasses, safety glasses, or goggles.

[0018] In some implementations of the foregoing device, the optical article includes a single optical member having opposing first and second lens surfaces. In some such implementations, the optical member includes: a magnet coupled to the optical member and configured to be coupled to the frame of the eye-wear device; a mounting bracket coupled to the optical member and configured to be coupled to the frame of the eye-wear device; or both.

[0019] In another aspect of the present disclosure, a method of forming one or more optical devices may include forming a single optical member having opposing first and second lens surfaces. The method may further include coupling a magnet to the optical member. The magnet may be configured to be coupled to the frame of the eye-wear device. The method may further include providing a mounting bracket coupled to the optical member. The mounting bracket may be configured to be coupled to the frame of the eye-wear device.

[0020] In some implementations of the foregoing method, forming the optical member includes receiving a sheet and forming the optical member from the sheet. Additionally or alternatively, providing the mounting bracket may include forming the mounting bracket from the sheet, or coupling a support structure including the mounting bracket to the optical member.

[0021] In some implementations of the foregoing method, the method further includes forming a channel in a side surface of the optical member. The side surface may be located between the first and second lens surfaces. In some such implementations, the method includes positioning at least a portion of the support structure within the channel. The optical member may be coupled to the magnet, the mounting bracket, or both via the support structure.

[0022] In some implementations of the foregoing method, forming the optical member further includes forming a first portion including a lens having the first and second lens surfaces. In some such implementations, forming the optical member further includes forming a second portion extending from a side surface of the first portion. The side surface may be located between the first and second lens surfaces. In some implementations, the first and second portions are formed using a milling machine.

[0023] In some implementations of the foregoing method, the method further includes forming a frame of the eye-wear device. The frame may have a first side and a second side. In some such implementations, the second side is the user-facing side. In some implementations, forming the frame may include: coupling a magnet to the second side, forming a cavity, or both. The cavity may be configured to receive at least a portion of a mounting bracket of the optical component. In some such implementations, the cavity may be defined by the frame of the eye-wear device. Additionally or alternatively, the cavity may be defined by a nose pad of the frame. In some such implementations, the nose pad is coupled to or integral with the frame.

[0024] As used herein, the various terms are for the purpose of describing particular implementations only and are not intended to limit the implementations. For example, as used herein, ordinal terms (e.g., "first", "second", "third", etc.) that modify elements such as structures, components, operations, etc. do not themselves indicate any priority or order of the element relative to another element, but merely distinguish the element from another element having the same name (but using an ordinal term). The term "coupled" is defined as connected, but not necessarily directly and not necessarily mechanically; the two terms of "coupled" may be integral with each other. Unless the present disclosure expressly requires otherwise, the terms "a" and "an" are defined as one or more.

[0025] As used herein, the term "about" can permit a degree of variability of a value or range, e.g., within 10%, 5%, or 1% of a stated value or of a stated range limitation, and includes the exact stated value or range. As understood by one of ordinary skill in the art, the term "substantially" is defined to mean to a great extent but not necessarily all of the specified content (and includes the specified content, e.g., substantially 90 degrees includes 90 degrees, and substantially parallel includes parallel). In any disclosed implementation, the term "substantially" can be replaced with "within [percentage] of" the specified content, where the percentage includes 0.1%, 1%, or 5%; and the term "approximate" can be replaced with "within 10 percent of" the specified content. Unless otherwise indicated, the statement "substantially X to Y" has the same meaning as "substantially X to substantially Y". Similarly, unless otherwise indicated, the statement "substantially X, Y, or substantially Z" has the same meaning as "substantially X, substantially Y, or substantially Z". The phrase "and / or" means and or. For illustration, A, B, and / or C includes: A alone, B alone, C alone, a combination of A and B, a combination of A and C, a combination of B and C, or a combination of A, B, and C. In other words, "and / or" is used as an inclusive "or". Similarly, the phrase "A, B, C, or combinations thereof" or "A, B, C, or any combination thereof" includes: A alone, B alone, C alone, a combination of A and B, a combination of A and C, a combination of B and C, or a combination of A, B, and C.

[0026] Throughout this document, values expressed in a range format should be interpreted in a flexible manner to include not only the numerical values explicitly recited as range limitations, but also all individual numerical values or sub-ranges subsumed within that range as if each numerical value and sub-range were explicitly recited. For example, a range of "about 0.1% to about 5%" or "about 0.1% to 5%" should be interpreted to include not only about 0.1% to about 5%, but also individual values within the specified range (e.g., 1%, 2%, 3%, and 4%) and sub-ranges (e.g., 0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%).

[0027] The terms "comprise" (and any form of comprise, such as "comprises" and "comprising"), "have" (and any form of have, such as "has" and "having"), and "include" (and any form of include, such as "includes" and "including"). As a result, a device that "comprises", "has", or "includes" one or more elements has those one or more elements, but is not limited to having only those one or more elements. Similarly, a method that "comprises", "has", or "includes" one or more steps has those one or more steps, but is not limited to having only those one or more steps.

[0028] Any implementation of any of the fabrication systems, methods, and articles of manufacture may consist of or consist essentially of any one of the described steps, elements, and / or features, rather than comprising / having / including any one of the described steps, elements, and / or features. Thus, in any claim, the terms "consisting of" or "consisting essentially of" may replace any of the above-described open-ended linking verbs in order to change the scope of a given claim from what it would otherwise be using an open-ended linking verb. Additionally, the term "wherein" may be used interchangeably with "where".

[0029] Further, a device or system configured in a certain way is at least configured in that way, but may also be configured in other ways than the specifically described way. Unless the nature of the present disclosure or implementation clearly prohibits it, one or more features of one implementation may be applied to other implementations even if not described or stated.

[0030] Some details associated with the implementations have been described above, and other details are described below. After reviewing the entire application, other implementations, advantages, and features of the present disclosure will become apparent, including the following sections: Brief Description of the Drawings, Detailed Description, and Claims.

[0031] The following figures are illustrative and non - limiting. For simplicity and clarity, not every feature of a given structure is always labeled in every figure in which that structure appears. Identical reference numerals do not necessarily indicate identical structures. Instead, the same reference numeral may be used to indicate similar features or features having similar functions, much like different reference numerals. Unless otherwise noted, the views in the figures are drawn to scale, which means that for at least the implementations in that view, the dimensions of the depicted elements are accurate relative to each other.

[0047] Referring to Figure 1A and Figure 1B , perspective views showing different configurations of an optical system are shown and generally designated as 100. For example, Figure 1A is a first perspective view (e.g., a front perspective view) of the optical system in a first configuration (e.g., an uncoupled state), and Figure 1B is a second perspective view (e.g., a rear perspective view) of the Figure 1A optical system in a second configuration (e.g., a coupled state).

[0048] As Figure 1A and Figure 1B shown, the optical system 100 includes an optical article 101 and an eye-wear device 130. In some implementations, the optical article 101 may be configured to be coupled to the eye-wear device 130, such as sunglasses. As further described herein, the optical article 101 is configured to removably couple with the eye-wear device 130. By way of illustration, and not limitation, the optical article 101 may include prescription lenses (e.g., "attachment" prescription lenses) that are configured to be coupled to the eye-wear device 130, such as a pair of sunglasses.

[0049] Referring to Figure 1A , the optical article 101 includes an optical member 102 and one or more attachment devices 104 (e.g., one or more attachment members). The optical member 102 may include or correspond to one or more lenses, such as prescription lenses, non-prescription lenses, magnifying lenses, etc. As shown, the optical member 102 corresponds to a single lens, such as a single prescription lens corresponding to one of the user's eyes. In other implementations, the optical member 102 may include or correspond to multiple prescriptions, such as a first prescription for the user's first eye and a second prescription for the user's second eye.

[0050] The optical component 102 includes a first end 106 and a second end 108 opposite the first end 106. In some implementations, the first end 106 may correspond to the right side, and the second end 108 may correspond to the left side. Additionally or alternatively, the optical component may include a third end 110 (e.g., the top side) and a fourth end 112 (e.g., the bottom side). The optical component 102 also includes a first surface 114 and a second surface 116 (as Figure 1B shown). The first surface 114 may include or correspond to the front surface (e.g., the first lens surface), and the second surface 116 may include or correspond to the rear surface (e.g., the second lens surface).

[0051] In some implementations, the optical component 102 may include a single optical component, such as a single prescription lens. Although the optical system 100 is shown as having one optical component 102, in other implementations, the optical system 100 may include multiple optical components (e.g., 102). In some such implementations, one or more of the optical components (e.g., 102) may have the same prescription or different prescriptions. For example, the first optical component may correspond to the user's right eye, and the second optical component may correspond to the user's left eye. The first optical component may correspond to a first prescription (or no prescription), and the second optical component may correspond to a second prescription (or no prescription).

[0052] One or more attachment devices 104 are configured to enable the optical component 102 (e.g., the optical article 101) to be coupled to (e.g., removably coupled to) the eye-wear device 130. One or more attachment devices 104 may be directly or indirectly coupled to the optical component 102. As Figure 1A shown, the optical article 101 includes a first attachment device 104 (as indicated by the solid line box). The optical article 101 may also include an optional second attachment device 104 (as indicated by the dashed line box). In some implementations, the optical article 101 may include a first attachment device (e.g., 104) positioned at the first end 106 and a second attachment device (e.g., 104) positioned at the second end 108. Although described as having one attachment device (and an optional second attachment device), this description is not intended to be limiting, and the optical article 101 may have one, two, three, four, or more attachment devices (e.g., 104). As illustrative but non-limiting examples, one or more attachment devices 104 may include or correspond to magnets, mounting brackets, adhesives, cavities, protrusions, a portion of Velcro (e.g., hooks and / or loops), friction devices, adhesives, male / female connectors (e.g., protrusions or recesses), other fasteners (e.g., pins, hooks, and loops, etc.), the like, or combinations thereof.

[0053] The eyewear device 130 may include or correspond to an eyeglass product (e.g., an eyeglass article), sunglasses, safety glasses, or goggles. As shown, the eyewear device 130 includes a frame 132 (e.g., a frame rim), one or more lenses 134, a nose pad 136, one or more attachment devices 138 (e.g., one or more attachment members), and one or more temple arms 140. Although the eyewear device 130 is described as including each of the frame 132, one or more lenses 134, the nose pad, and one or more temple arms 140, in other implementations, the eyewear device may not include one or more of the frame 132, one or more lenses 134, the nose pad, and one or more temple arms 140. In a particular implementation, the eyewear device 130 includes sunglasses, and one or more lenses 134 (such as non-prescription lenses) include tinted lenses and / or polarized lenses, by way of illustrative and non-limiting example.

[0054] The frame 132 may include a plurality of rims for receiving, holding, retaining, and / or supporting the lenses 134. Although the frame 132 is shown as having rims surrounding the lenses 134, this should not be considered limiting, and it should be understood that the rims may not completely surround the lenses 134. In some implementations, the nose pad 136 may be defined by a portion of the frame configured to rest on the user's nose when the user is wearing the eyewear device 130. Although described as including the nose pad 136, in other implementations, the eyewear device 130 may not include a nose pad.

[0055] One or more attachment devices 138 are configured to be coupled to (e.g., removably coupled to) or cooperate with one or more attachment devices 104 of the optical article 101. For example, a first attachment device 138 may be configured to selectively or removably couple the optical article 101 to the eyewear device 130. For example, a first attachment device (e.g., 138) of the eyewear device 130 may be configured to couple to and form an interface connection with a first attachment device (e.g., 104) of the optical article 101. By way of illustration, a first attachment device (e.g., 138) of the eyewear device 130 may contact a first attachment device (e.g., 104) of the optical article 101 to couple the optical article 101 to the eyewear device 130. Additionally or alternatively, a second attachment device (e.g., 138) of the eyewear device 130 may be configured to couple to and form an interface connection with a second attachment device (e.g., 104) of the optical article 101. In some implementations, one or more attachment devices 138 are configured such that multiple optical articles (e.g., 101) can be coupled to the eyewear device 130, such as a first optical article (e.g., 101) positioned relative to a first lens (e.g., 134) and a second optical article (e.g., 101) positioned relative to a second lens (e.g., 134). In a particular implementation, the eyewear device includes at least one attachment device 138 that is configured such that a first optical member and a second optical member of a single optical article can be removably coupled to the eyewear device 130.

[0056] (Multiple) attachment devices 138 may be positioned along a portion of the frame 132, such as along the eyewire, the bridge, the nose pad 136, etc., or a combination thereof, as illustrative and non-limiting examples. For example, one attachment device 138 may be positioned on one side of the lens 134, and another attachment device 138 may be positioned on the opposite side of the lens. As illustrative and non-limiting examples, one or more attachment devices 138 may include or correspond to magnets, mounting brackets, adhesives, cavities, protrusions, a portion of Velcro (e.g., hooks and / or loops), friction devices, adhesives, male / female connectors (e.g., protrusions or recesses), other fasteners (e.g., pins, hooks and loops, etc.), the like, or a combination thereof. In a particular implementation, one or more attachment devices 138 include magnets coupled to the frame 132 at a location near the temple 140 and include mounting cavities defined in the frame 132 and / or the nose pad 138. It should be noted that when one or more attachment devices 138 include magnets, the magnets may be positioned within a cavity of the frame 132 such that the interface surface of the magnet does not extend or protrude beyond the surface of the frame 132. Additionally or alternatively, the magnets may be embedded within the frame 132.

[0057] ReferenceFigure 1B The optical article 101 is coupled to the eyewear device 130. In some implementations, each attachment device 104 can be coupled to a corresponding attachment device 138 at a connection point to secure the optical article 101 to the frame 132. The connection point can define an interface between components (e.g., 101 and 130), such as a magnetic interface, a mechanical interface, or both). One or more attachment devices 104 can be positioned on the optical article 101 such that each attachment device 104 (among the one or more attachment devices 104) is aligned with a corresponding attachment device 138 of the eyewear device 130 to couple the optical article 101 to the eyewear device 130 in a predetermined orientation. For example, the optical article 101 can be configured to be coupled to the eyewear device 130 such that the optical article covers an existing lens (e.g., 134) of the eyewear device 130 from the rear of the lens.

[0058] During operation, a first optical article (e.g., 101) is coupled to the rear portion of the eyewear device 130 relative to a first lens (e.g., 134) of the frame 132. For example, a first attachment device (e.g., 104) of the first optical article (e.g., 101) can be coupled to a first attachment device (e.g., 138) of the frame 132. After the first optical article (e.g., 101) is coupled to the rear portion of the eyewear device 130 relative to the first lens (e.g., 134) of the frame 132, the first optical article (e.g., 101) is separated from the rear portion of the eyewear device 130 relative to the first lens (e.g., 134) of the frame 132.

[0059] In some implementations, a second optical article (e.g., 101) is coupled to the rear portion of the eyewear device 130 relative to a second lens (e.g., 134) of the frame 132. For example, a second attachment device (e.g., 104) of the second optical article (e.g., 101) can be coupled to a second attachment device (e.g., 138) of the frame 132. After the second optical article (e.g., 101) is coupled to the rear portion of the eyewear device 130 relative to the second lens (e.g., 134) of the frame 132, the second optical article (e.g., 101) is separated from the rear portion of the eyewear device 130 relative to the second lens (e.g., 134) of the frame 132.

[0060] In an implementation where the eyewear device 130 includes sunglasses and the optical article 101 includes prescription lenses, the optical article 101 can be selectively coupled and decoupled by the user. In this way, the optical article 101, including the prescription lenses, can be attached and removed by the user. Accordingly, the optical article 101 can be capable of selectively transforming the eyewear device (e.g., sunglasses) into prescription sunglasses. This can allow an individual who switches between prescription eyewear and contact lenses to wear the same pair of sunglasses by easily removing or attaching the optical article 101 from the sunglasses (e.g., 130).

[0061] In some implementations, the optical article 101 is configured to be used with the eyewear device 130. In such implementations, the optical article 101 includes an optical member 102, such as a single optical member, having a first surface 114 and a second surface 116. In some implementations, the first surface 114 includes or corresponds to the front surface, and the second surface 116 includes or corresponds to the rear surface. The optical article 101 can include one or more attachment devices 104 configured to couple (e.g., removably couple) the optical article 101 to the eyewear device 130. For example, the optical article 101 can be configured to couple to the rear side of the frame 132 of the eyewear device. In a particular implementation, the attachment device (e.g., 104) can include a magnet coupled to the optical member 102 and configured to couple to the frame (e.g., 132) of the eyewear device (e.g., 130). Additionally or alternatively, the attachment device (e.g., 104) can include a mounting bracket coupled to the optical member 102 and configured to couple to the nose pad of the frame (e.g., 132) of the eyewear device (e.g., 130).

[0062] In additional implementations, the optical article 101 is configured to be used with the eyewear device 130 and includes an optical member 102, such as a single optical member, having opposing first lens surface 114 and second lens surface 116. The optical article 101 can include: a magnet (e.g., 104) coupled to the optical member 102 and configured to couple to the frame 132 of the eyewear device 130; a mounting bracket (e.g., 104) coupled to the optical member 102 and configured to couple to the frame 132 of the eyewear device 130; or both.

[0063] In one or more implementations, the optical article 101 can include a support structure coupled to the optical member 102, as at least referenced herein Figure 2Ais further described. The size, shape, or both of the support structure are based on one or more characteristics of the frame 132 of the eye-wear device 130. In some such implementations, the optical member 102 is coupled to a magnet (e.g., 104) via the support structure, and the mounting bracket (e.g., 104) is coupled to or integral with the support structure and has both the magnet and the mounting bracket. Additionally or alternatively, the optical member 102 includes a channel formed through a side surface of the optical member 102. The side surface may be positioned between a first surface 114 and a second surface 116. In such an implementation, at least a portion of the support structure may be positioned within the channel.

[0064] In one or more implementations, the optical member 102 includes a prescription lens and is configured to be coupled to the user-facing side (e.g., the rear side) of the frame 132 using a magnet (e.g., 104a) and a mounting bracket (e.g., 104b). Additionally or alternatively, the optical member 102 may be configured to be coupled to the eye-wear device 130 such that when the user is wearing the eye-wear device, the optical member 102 is positioned between the frame 132 and the user of the eye-wear device.

[0065] In some one or more implementations, the eye-wear device 130 includes a frame 132 having a first side and a second side. The second side may be the user-facing side. In some such implementations, the frame 132 includes a nose pad 136 that includes: a cavity configured to receive a mounting bracket arm (e.g., 104) of the optical article 101; a magnet coupled to the second side and configured to be coupled to a magnet (e.g., 104) of the optical article 101; or a combination thereof. In a particular implementation, to couple the optical member 102 to the frame 132, the magnet (e.g., 104) is configured to be positioned within a first cavity of the frame 132, at least a portion of the mounting bracket (e.g., 104) is configured to be positioned within a second cavity of the frame 132, or both are performed. Some implementations include one or more lenses 134 coupled to the optical frame 132, where each of the one or more lenses (e.g., 134) is different from the optical member 102. The eye-wear device 130 may be a device selected from the group consisting of: an eyewear product, an eyewear article, sunglasses, safety glasses, or goggles.

[0066] In one or more implementations, the optical member 102 includes a first portion and a second portion, as at least referenced Figures 3A to 3CAs described. For example, the first part may include a lens having a first surface 114 and a second surface 116. The second part may extend from a side surface of the first part. In some such implementations, the side surface is positioned between the first surface 114 (e.g., the first lens surface) and the second surface 116 (e.g., the second lens surface). The second part may be coupled to, in contact with, or include one or more attachment devices 104. For example, the second part may be coupled to, in contact with, or include a magnet, a mounting bracket, or both.

[0067] Accordingly, system 100 provides an eye wear device 130 and one or more optical articles 101 (e.g., one or more prescription attachments) that can be selectively coupled / decoupled with the eye wear device 130. Accordingly, system 100 can advantageously provide versatility to the eye wear device 130 such that a user does not need to have both prescription and non-prescription forms of the eye wear device, which can beneficially reduce the user's cost. Accordingly, the optical article 101 can enable the management of different prescriptions such that the optical article can be replaced for a corresponding eye change prescription. It should also be noted that in implementations where the optical article 101 includes a single optical component (e.g., a single prescription lens), the optical article 101 (or two optical articles) can have a reduced weight compared to an optical article that includes two optical components (e.g., two prescription lenses).

[0068] Reference Figures 2A to 2D , views of one or more components of an example of an optical article are shown. For example, Figure 2A an example of an optical article 200 is shown, Figure 2B an optical component 202 of the optical article 200 is shown, Figure 2C a side view of the optical component 202 is shown, and Figure 2D an example of a support structure 260 is shown. The optical article 200 may include or correspond to the optical article 101.

[0069] As Figure 2A shown, the optical article 200 includes an optical component 202, one or more attachment devices 204 (e.g., 204a, 204b), and a support structure 260 (e.g., a frame or a ring). The optical component 202 and the attachment devices 204 may respectively include or correspond to the optical component 102 and one or more attachment devices 104.

[0070] The optical component 202 can be coupled to the support structure 260. For example, when the annulus is coupled to the optical component, the support structure 260 can surround (e.g., encircle) at least a portion of the optical component 202. As shown, the exposed portion of the support structure 260 has a distance 207 (e.g., width) extending outward from the perimeter of the optical component 202. In some implementations, one or more attachment devices 204 are coupled to or defined by the support structure 260, such as one or more attachment devices 204 being coupled to the exposed portion 261 of the support structure 260. One or more attachment devices 204 can be coupled to or integral with the support structure 260. As shown, one or more attachment devices 204 include a first attachment device 204a and a second attachment device 204b. Although the optical article 200 (e.g., the support structure 260) is shown as having two attachment devices 204 (e.g., 204a, 204b), in other implementations, the optical article 200 (e.g., the support structure 260) can include fewer than two attachment devices or more than two attachment devices.

[0071] Reference Figure 2B and Figure 2C , an optical component 202 is shown. For illustration, Figure 2B an optical component 202 of the optical article 200 without the support structure 260 is shown. The optical component 202 can have any suitable shape, such as the optical component 202 can be spherical, toric, aspherical, etc., or a combination thereof, as illustrative and non-limiting examples. In some implementations, the optical component 202 includes a lens (e.g., a prescription lens). As shown, a first end 206 is opposite a second end 208. The first end 206 and the second end 208 can respectively include or correspond to the first end 106 and the second end 108.

[0072] Reference Figure 2C , a side view of the optical component 202 is shown. The optical component 202 includes a first surface 210 (e.g., a front surface) and a second surface 212 (e.g., a rear surface). The first surface and the second surface are opposite lens surfaces of the optical component 202. In some implementations, each of the first surface 210 and the second surface 212 can be concave, convex, or planar. The optical component also includes one or more side surfaces, such as a first side surface 221 and a second side surface 222. The first side surface 221 can extend from the first surface 210 and can intersect the first surface 210 at a first edge 231. The second side surface 222 can extend from the second surface 212 and can intersect the second surface 212 at a second edge 232.

[0073] The optical member 202 may include a channel 218 configured to receive at least a portion of the support structure 260. The channel 218 (e.g., a groove) may be defined by a third side surface 223 (e.g., a channel bottom wall), a third surface 224 (e.g., a first channel side wall), and a fourth surface 225 (e.g., a second channel wall). The third surface 224 may extend from the second side surface 222 and may intersect the second side surface 222 at a third edge 233. The third side surface 223 may extend between the third surface 224 and the fourth surface 225. The third side surface 223 may intersect the third surface 224 to form a first corner and may intersect the fourth surface 225 to form a second corner. The fourth surface 225 may extend from the first side surface 221 and may intersect the first side surface 221 at a fourth edge 234. In some implementations, the optical member 202 may not include the first side surface 221 such that the first surface 210 and the fourth surface 225 intersect to form an edge. Although the channel 218 is shown and described as having corners (e.g., a rectangular shape), in other implementations, the channel may have different shapes such as U-shaped, V-shaped, oval, curved, smooth, wavy, other shapes, or combinations thereof, by way of illustrative and non-limiting examples.

[0074] The channel 218 may extend along a portion (e.g., at least a portion) or all of the perimeter of the optical member 202. The channel may be positioned between the first surface 210 and the second surface 212. In some implementations, the distance between the first surface 210 and the fourth surface 225 is the same as the distance between the second surface 212 and the third surface 224. In implementations, the distance between the first surface 210 and the fourth surface 225 is different from (e.g., greater than or less than) the distance between the second surface 212 and the third surface 224. The position of the groove relative to the first lens surface 210 may depend on the prescription (RX) of the optical member and / or the configuration of the frame of the eye wear device (e.g., 130). For example, the channel 218 may be positioned such that the gap (e.g., spacing) between the optical member 202 (e.g., an RX lens) and the lens of the eye wear device (e.g., 134) is minimized.

[0075] As Figure 2CAs shown, the channel 218 may have a depth 240 measured from the first side surface 221 or the second side surface 222. In some implementations, the depth 240 of the channel 218 is the maximum depth between the third side surface 223 and the first side surface 221 or between the third side surface 223 and the second side surface 222. The depth 240 may be greater than or equal to 0.1 mm, such as greater than or equal to 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm or greater, or between any two of them. In some implementations, the depth 240 of the channel 218 may vary. By way of illustration, the depth 240 may vary according to the interface pattern between the optical member 202 and the support structure 260.

[0076] The channel 218 may define a width 242 measured between the third surface 224 and the fourth surface 225. The width may be greater than or equal to 0.2 mm, such as greater than or equal to 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm or greater, or between any two of them. In some implementations, the width 242 of the channel 218 may vary. By way of illustration, the width 242 may vary according to the interface pattern between the optical member 202 and the support structure 260.

[0077] Reference Figure 2D , an example of the support structure 260 of the optical article 200 is shown. The support structure 260 may include an inner surface 262 and an outer surface 264. The distance 268 between the inner surface 262 and the outer surface 264 may be greater than or equal to the distance 207. The inner surface 262 may have a profile that is configured to interface (e.g., match) with a surface of the optical member, such as the third side surface 223, the third surface 224, the fourth surface 225, or a combination thereof. When the support structure 260 is coupled to the optical member 202, at least a portion of the support structure 260 may be positioned within the channel 218. For example, the support structure 260 may include an annular body having an inner surface 262 configured to engage the channel 218 and an outer surface 264 configured to extend away from the optical member 202 when a portion of the support structure is positioned within the channel 218. In some implementations, the support structure 260 may include an elastic material, metal, polymer (e.g., plastic), or a combination thereof, by way of illustrative and non-limiting examples.

[0078] The size, shape, or both of the support structure 206 are based on one or more characteristics of the eye-wear device (e.g., 130). In some implementations, the outer surface 264 can facilitate the engagement of the optical article 200 with the frame 230. By way of illustration, the outer surface 264 can be customized to engage the frame of a particular style and / or brand of eye-wear device. For example, the outer surface 264 of the support structure 206 can be defined by the geometry of the frame 232. As another example, the shape and size of the outer surface 264 can be determined to be supported by the frame, and the shape and size of the inner surface 262 can be determined to be at least 1 mm within an opening of the frame (such as a lens opening).

[0079] In some implementations, the support structure 206 can be fabricated separately from the optical member 202. By way of illustration, the inner surface 262 of the support structure 206 can be fabricated to snap or clip into the channel 218 such that the annulus and the optical member 202 can be frictionally coupled together. In other implementations, the support structure 206 and the optical member 202 can be integral (e.g., fabricated together). For example, the support structure 206 can be formed with the optical member 202 via an injection process (e.g., injection molding). Alternatively, the support structure 260 can be removably coupled to the optical member 202 such that different support structures (e.g., 260) can be coupled to the optical member to enable the optical member 202 to be coupled to different eye-wear devices.

[0080] In some implementations, the support structure 260 can be transparent to allow for optimal visibility, while in other implementations, the support structure can be colored to provide customization and aesthetic appeal. For example, the support structure 260 can be the same color as the frame (e.g., 132), or a different color (e.g., an accent color) to serve as a style element.

[0081] One or more attachment devices 204 can be configured to structurally couple the optical member 202 to the eye-wear device. As shown, a first attachment device 204a and a second attachment device 204b are coupled to the support structure 260. As an illustrative, non-limiting example, the first attachment device 204a can include a magnet, and the second attachment device 204b can include a protrusion, such as a mounting bracket. Additionally or alternatively, at least one attachment device 204 can be configured to non-structurally (e.g., chemically, magnetically, electromagnetically, etc.) couple the optical member 202 to the eye-wear device.

[0082] In some implementations, the optical article 200 is configured to be used with an eyewear device 130. In such an implementation, the optical article 200 includes an optical member 202, such as a single optical member, having a first surface 210 and a second surface 212. In some implementations, the first surface 210 includes or corresponds to a front surface, and the second surface 212 includes or corresponds to a rear surface. The optical article 202 may include one or more attachment devices 204 configured to couple (e.g., removably couple) the optical article 200 to the eyewear device. For example, the optical article 200 may be configured to couple to the rear side of the frame of the eyewear device. In some implementations, the optical article 200 further includes a support structure 260. In a particular implementation, the optical member 202 is coupled to at least one attachment device 204 via the support structure 260. Additionally or alternatively, at least a portion of the support structure 260 may be positioned within a channel of the optical member 202.

[0083] In additional implementations, the optical article 200 is configured for use with an eyewear device 230 and includes: an optical member 202 having opposing first lens surface 210 and second lens surface 212; a magnet (e.g., 204a) coupled to the optical member 202 and configured to couple to the frame of the eyewear device; and a mounting bracket (e.g., 204b) coupled to the optical member 202 and configured to couple to the frame of the eyewear device. In some implementations, the optical article 200 may include a single optical member (e.g., 202).

[0084] In one or more implementations, the optical member 202 includes a channel 218 formed via one or more side surfaces of the optical member 202. The one or more side surfaces are positioned between the first surface 210 and the second surface 212. In some implementations, the optical member 202 includes a prescription lens and is configured to couple to the user-facing side of an eyewear device (e.g., 130).

[0085] In one or more implementations, the optical article 200 further includes a support structure 260 that is coupled to the optical member 202. The size, shape, or both of the support structure (e.g., 260) are based on one or more characteristics of the frame of the eyewear device. In some implementations, at least a portion of the support structure 260 is positioned within the channel 218 of the optical member 202. Additionally or alternatively, the optical member 202 may be coupled to one or more attachment devices 204 via the support structure 260. By way of illustration, the optical member 202 may be coupled to a magnet, a mounting bracket, or both via the support structure 260. For example, the magnet, the mounting bracket, or both may be in contact with or integral with the support structure 260. The magnet may be configured to be positioned within a first cavity of the frame. At least a portion of the mounting bracket is configured to be positioned within a second cavity of the frame.

[0086] The optical member 202 and the support structure 260 may be utilized Figures 2A to 2D such that the support structure 260 couples the optical member 202 to the eyewear device, allowing the optical member 202 to be used with a wide range of prescriptions. For example, for a highly negative prescription, the radius of the lens (e.g., the optical member 202) is small, and the distance between the lens and the eye is small. As a result, the eyelashes may potentially touch the prescription lens. Using the support structure 260 allows for the use of a highly negative prescription lens (e.g., the optical member 202) by increasing the width between the inner surface and the outer surface of the support structure 260 (e.g., 262 and 264). Similarly, the support structure 260 may be designed to couple a highly positive prescription lens to the eyewear device 230 without the optical member 202 interfering with the lens of the eyewear device (e.g., 134) or the wearer's eyelashes. In other words, the support structure 260 (or the exposed portion of the support structure 260 when coupled to the optical member 202) may be customized based on the prescription of the optical member 202 and the frame of the eyewear device (e.g., 132). Additionally, the support structure 260 allows for the easy replacement of a broken or damaged lens (e.g., 202). The user may attach or remove the support structure 260 to easily replace the optical member 202 without the need for professional services provided by, for example, an optician, an ophthalmologist, an optometrist, etc.

[0087] Reference Figures 3A to 3C is made to Figure 3A which shows views of one or more components of an example of an optical article. For example, Figure 2B shows an example of an optical article 300, Figure 2C shows a side view to illustrate one or more aspects of the optical member 202, and

[0088] Reference Figure 3A ,The optical article 300 may include an optical component 302 and one or more attachment devices 304 (e.g., a first attachment device 304a and a second attachment device 304b). The optical component 320 may include or correspond to the optical components 102, 202. The one or more attachment devices 304 may include or correspond to the attachment device 104 and / or the attachment device 204 (e.g., a first attachment device 204a, a second attachment device 204b).

[0089] The optical article 300 may include a single optical lens (e.g., a prescription lens for the eye). The optical component 302 may include a first end 306 and a second end 308. In some implementations, the optical article 300 includes: a first portion 316 that includes or corresponds to the optical component 302; and a second portion that includes or corresponds to an extension portion. The one or more attachment devices 304 may be coupled to the extension portion. For example, the one or more attachment devices 304 may be in contact with or integral with the second portion. As Figure 3A shown, at least one attachment device 304 is positioned at each of the first end 306 and the second end 308, such as the first attachment device 304a is positioned at the first end 306 and the second attachment device 304b is positioned at the second end 308. However, it should be noted that the one or more attachment devices 304 may be positioned at different locations on the optical article 300. Although the optical article 300 is described as having two attachment devices 304, in other implementations, the optical article may include fewer or more than two attachment devices 304.

[0090] Reference Figure 3B and Figure 3C show a side view of the optical article 300 and a portion 314 of the side view. It should be noted that one or more aspects of the optical article 300, such as the one or more attachment devices 304, are not shown in Figure 3B and Figure 3C .

[0091] The optical article 300 includes a first surface 310 (e.g., a front surface) and a second surface 312 (e.g., a rear surface). Each of the first surface 310 and the second surface 312 can be concave, convex, or planar. The optical article 300 also includes one or more side surfaces, such as a first side surface 321 and a second side surface 322. The first side surface 321 can extend from the first surface 210 and can intersect the first surface 310 at a first edge 331. The second side surface 322 can extend from the second surface 312 and can intersect the second surface 312 at a second edge 332. The optical article 300 can also include a third surface 323. The third surface 323 can extend from the second surface 322 and can intersect the second surface 322 to form a third edge 333. Additionally or alternatively, the third surface 323 can extend from the first surface 321 and can intersect the first surface 321 at a corner. The first side surface 321 and the third surface 323 can form a flange (e.g., a step or a shelf) of the optical article 300.

[0092] The optical member 202 can include a channel 218 configured to receive at least a portion of the support structure 260. The channel 218 (e.g., a groove) can be defined by a third side surface 223 (e.g., a channel bottom wall), a third surface 224 (e.g., a first channel side wall), and a fourth surface 225 (e.g., a second channel wall). The third surface 224 can extend from the second side surface 222 and can intersect the second side surface 222 at a third edge 233. The third side surface 223 can extend between the third surface 224 and the fourth surface 225. The third side surface 223 can intersect the third surface 224 to form a first corner and can intersect the fourth surface 225 to form a second corner. The fourth surface 225 can extend from the first side surface 221 and can intersect the first side surface 221 at a fourth edge 234. In some implementations, the optical member 202 can not include the first side surface 221 such that the first surface 210 and the fourth surface 225 intersect to form an edge.

[0093] As shown, the maximum lateral dimension of the second side surface 322 is greater than the maximum lateral dimension of the first side surface 31. The first side surface 321 and the second side surface 322 are connected via a third surface 323. The third surface 323 may extend along a plane that is substantially orthogonal to the first sidewall 321 and the second sidewall 322. In some implementations, the third surface 323 is parallel to at least a portion of each of the first surface 310 and the second surface 312. The first side surface 321 and the third surface 326 may cooperate to define a flange along the perimeter of the optical member 302 such that the flange may cooperate with the frame of the eye-wear device to orient the optical member 300 (e.g., the optical article 300) within the frame. As an illustrative but non-limiting example, the size and / or shape of the flange may be based on one or more dimensions of the frame and may be formed in the optical article 300 using a milling machine (such as a three-axis milling machine). In some implementations, the frame is scanned or traced with an optician's tracing device and the flange is fabricated based on the completed scan / trace. For example, a similar enlargement may be performed to accurately orient the optical member 202 within the frame (e.g., 132).

[0094] In some implementations, the third surface 233 may define a width 327 measured between the first surface 321 and the second surface 322 in a direction perpendicular to the second side surface 332, the width being greater than or equal to 0.1 mm, such as greater than or equal to 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm or greater, or between any two of them. In some implementations, for proper support on the frame, the width 327 of the optical member 302 is at least 1 mm. Additionally or alternatively, the first surface 321 may have a thickness 242 measured from the first surface 310 to the third surface 323, the thickness being greater than or equal to 0.05 mm, such as greater than or equal to 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm or greater, or between any two of them. In some implementations, the thickness 242 is greater than or equal to the width 327. Additionally or alternatively, the thickness 242 (e.g., the depth of the flange) may be selected at a position where 310 is close to the surface of the lens of the frame (of the eye-wear device) without contacting the surface of the lens. For example, the distance between the first surface 310 and the surface of the lens of the frame may be less than or equal to 1 mm, such as less than or equal to 0.5 mm or 0.25 mm.

[0095] Note that one or more attachment devices 304 may be coupled to and / or in contact with the second surface 322 and / or the third surface 323. For example, a mounting bracket may be coupled to the second surface 322. As another example, a magnet may be coupled to the third surface 323.

[0096] In some implementations, the optical article 300 may be configured for use with an eyewear device. In some implementations, the optical article 300 includes an optical component 302, such as a single optical component, having opposing first and second lens surfaces (e.g., 310 and 312). In some implementations, the optical article 300 includes a magnet (e.g., 304a) coupled to the optical component 302 and configured to be coupled to a frame (e.g., 132) of an eyewear device (e.g., 130). In some implementations, the optical article 300 includes a mounting bracket (e.g., 304a) coupled to the optical component 302 and configured to be coupled to a frame of an eyewear device.

[0097] In some implementations, the optical article 300 includes: a first portion 312 that includes a lens having first and second lens surfaces (e.g., 310 and 312); and a second portion that extends from a side surface (e.g., 321) of the first portion 316. The side surface may be located between the first and second lens surfaces (e.g., 310 and 312). The second portion may be coupled to or include one or more attachment devices 304, such as a mounting bracket (e.g., 304a), a magnet (e.g., 304b), or a combination thereof, by way of illustrative and non-limiting example. For illustration, a mounting bracket (e.g., 304a) may be coupled to the optical component 302 and configured to be coupled to a frame of an eyewear device. Additionally or alternatively, a magnet (e.g., 304b) may be coupled to the optical component 302 and configured to be coupled to a frame of an eyewear device.

[0098] In one or more implementations, the optical component 302 includes a prescription lens. The optical component 302 may be configured to be coupled, such as via one or more attachment devices 304, to the user-facing side of a frame (e.g., 132).

[0099] Figures 3A to 3CThe optical article 300 can be used to allow the optical component 302 to be used with one or more eyewear devices. The optical article 300 having a flange formed by at least one side surface of the optical component 302 can enable a small gap to exist between the first surface 310 of the optical component 302 and the lens (e.g., 134) of the eyewear device. This positioning can make the use of the optical article 300 less noticeable compared to an eyewear device without the optical article 300. Additionally or alternatively, compared to the optical article 200, the optical article 300 includes an integrated design such that the number of components is reduced, which can be fabricated faster, reduce costs, and can have tighter tolerance control, thereby providing a secure fit between the optical article 300 and the frame.

[0100] Now referring to Figures 4A to 4D , a view showing one or more examples of the eyewear device 400 is shown. Figure 4A A rear perspective view of the eyewear device 400 is shown. Figures 4B to 4D A rear view showing an example of an eyewear device coupled to a different optical article is shown.

[0101] Referring to Figure 4A , the eyewear device 400 can include or correspond to the eyewear device 130. The eyewear device 400 can include or correspond to, by way of illustrative and non-limiting examples, eyewear products, glasses, spectacle articles, sunglasses, safety glasses, goggles (e.g., safety goggles, ski goggles, diving goggles, etc.), and the like.

[0102] As shown, the eyewear device 430 includes a frame 432, one or more lenses 434, a nose pad 436, and one or more attachment devices 438. The frame 432, lenses 434, nose pad 436, and one or more attachment devices 436 can respectively include or correspond to the frame 132, lenses 134, nose pad 136, and one or more attachment devices 136. As shown, the lenses 434 and the attachment devices 438 are coupled to or defined by the frame 432. In some implementations, one or more attachment devices 438 can be integral with or integrated into the frame 432.

[0103] The frame 432 is configured to receive, hold, secure, and / or support one or more lenses 434 such that the lenses can be aligned relative to each other or arranged side by side for placement in front of the wearer's respective eyes when the eyewear device is worn. The frame 432 can include a first side 442, a second side 444, one or more cavities 446, one or more lens rims 448, a bridge 450, and nose pads 436. As shown, the first side 442 is opposite the second side 444. In an implementation where the user wears the eyewear device 430, the second side 444 is the side facing the user (e.g., closer to the user's eyes).

[0104] The frame 432 can include one or more lens rims (or lens rim frames) 448 that are configured to receive, hold, secure, and / or support each of the one or more lenses 434. As shown, the frame 432 can include two lens rims 448a, 448b arranged side by side. Each of the two lens rims 448a, 448b can be a full lens rim. For example, each lens rim 448a, 448b can include an annular body that defines a closed opening in which a component (e.g., the lens 434) can be placed. In some implementations, the lens rim 448 can be configured to receive optical articles such as optical article 101, optical article 200, or optical article 300. According to various implementations, the lens rim 448 can also be a half lens rim, or the frame 432 can be without any lens rims. Accordingly, the frame 432 can be a full-frame, half-frame, or rimless frame.

[0105] The frame 432 can also include a bridge 450. The bridge 450 can be a part of the frame 432 that extends between the two lens rims 448a and 448b. In some implementations, the bridge 450 can be connected to the lenses 434. Accordingly, the bridge 450 can be positioned between the first lens and the second lens 434. Further, when the eyewear device 430 is worn, the bridge 450 can be above the wearer's nose.

[0106] The frame 432 can also include nose pads 436. In some implementations, the nose pads 436 can be defined by a part of the second side 444, while in other implementations, the nose pads 436 can include a member that is coupled to the second side 444 of the frame 432 and extends away from the second side. The nose pads 436 can be defined by the lens rims 448, or coupled to the lens rims. As shown, the frame 432 can include two nose pads 436 defined by a part of each lens rim 448. In some implementations, the nose pads 436 can be defined by the user-facing side (e.g., the second side 444) of the lens rim 448 that is directly below the bridge 450. Although described as having nose pads 436, in other implementations, the frame 432 can be without nose pads 436.

[0107] In some implementations, the frame 432 can include one or more attachment devices 446 (e.g., one or more attachment features). For example, the one or more attachment features 446 can include or correspond to one or more attachment devices 138. By way of illustration, the one or more attachment devices 446 can include one or more cavities (e.g., recesses) defined on a second side 444 of the frame 342. Each of the one or more attachment features 446 can be configured to couple to an attachment device of an optical article (e.g., 101, 200, 300) to couple the frame 432 and the optical article. As shown, the frame includes a first attachment device 446a (e.g., a magnet) and a second attachment device 446b (e.g., a cavity). It should be noted that the one or more attachment devices 446 can additionally or alternatively be located on the lens rim 448 and / or the bridge 450. The attachment device 446 can be located at any suitable location of the frame 432. In this way, at least one optical article can be coupled to the frame 432 such that the optical article covers the corresponding lens (e.g., 434). It should also be noted that the one or more attachment devices 446 do not affect the comfort of the user or the frame when the frame is worn by the user without being coupled to one or more optical articles.

[0108] In some implementations, the first attachment device 446a can include a magnet, a cavity, a protrusion, or a combination thereof. For example, the magnet can be located within the cavity, and the opening of the cavity can have a protrusion. The first attachment device 446a can be configured to receive a mating attachment device of an optical article, which is configured to interface with the first attachment device 446a. In some implementations, the second attachment device 446b can include a cavity configured to receive a protrusion (e.g., a mounting bracket) of an optical article.

[0109] Now referring Figures 4B to 4D , an example of an optical article 400 is shown coupled to a frame 432 of an eye-wear device 430 (e.g., sunglasses). For example, Figure 4B an optical article 470 is shown coupled to the frame 432, Figure 4C an optical article 480 is shown coupled to the frame 432, and Figure 4D an optical article 490 is shown coupled to the frame 432.

[0110] Referring Figure 4B and Figure 4C , Figure 4B and Figure 4CThe optical articles 470 and 480 may include or correspond to the optical article 200. For example, the optical article 470 may include one or more attachment mechanisms 204 (e.g., 204a, 204b), an optical member 202 (e.g., 202a), and a support structure 260 (e.g., 260a). The optical article 480 may include one or more attachment mechanisms 204 (e.g., 204a, 204b), an optical member 202 (e.g., 202b), and a support structure 260 (e.g., 260b). Each of the optical articles 470, 480 may be coupled to a location on the frame 432 corresponding to the user's left eye. Compared with Figure 4C the exposed portion of the support structure 260b of Figure 4B the exposed portion of the support structure 260a of Figure 4C the optical member 202b of Figure 4B the optical member 202a of Figure 4B and Figure 4C illustrate that different support structures (e.g., 260) may be used to enable different sized optical members (e.g., 202) to be used with the same eyewear device 400. The size and shape of each support structure (e.g., 260) may be selected for a particular optical member (e.g., 202) and a particular frame (e.g., 432). Additionally or alternatively, the size of each support structure (e.g., 260) may be determined by a prescription lens (such as an optical member), and / or by the positioning of the optical member relative to the user's corresponding eye.

[0111] Referring to Figure 4D , the optical article 490 may include or correspond to the optical article 300. For example, the optical article 490 may include an optical member 302 (e.g., 302a) and one or more attachment devices 304 (e.g., 304a, 304b). The optical article 490 may be coupled to a location on the frame 432 corresponding to the user's right eye.

[0112] In some implementations, the eyewear device 430 is configured to be coupled to an optical article (e.g., 101, 200, 300, 470, 480, 490), an optical component 402. In some implementations, the eyewear device 430 includes a frame 432 having a first side 442 and a second side 444, the second side being the user-facing side. The frame 432 includes one or more attachment devices 446. For example, the one or more attachment devices may include: a cavity configured to receive a mounting bracket arm of the optical article; a magnet coupled to the second side and configured to magnetically couple with a magnet of the optical article; or both. Additionally or alternatively, the eyewear device 430 may include one or more lenses 434 coupled to the optical frame 432, each of the one or more lenses being different from the optical article 402. The eyewear device 430 may include a device selected from the group consisting of: an eyewear product, an eyewear article, sunglasses, safety glasses, or goggles.

[0113] Accordingly, Figures 4A to 4D An illustrative example of an eyewear device 400 for use with one or more optical articles (e.g., 101, 200, 300, 470, 480, 490) is provided. For illustration, the eyewear device 400 may be coupled to a single optical article or multiple articles, such as a first optical article (e.g., 101, 200, 300, 470, 480, 490) corresponding to the left eye and a second optical article (e.g., 101, 200, 300, 470, 480, 490) corresponding to the right eye. Accordingly, a user may be able to use one or more optical articles (e.g., prescription attachments) with one or more eyewear devices, and a particular eyewear device may be used with various optical articles. Thus, an optical system (e.g., 100) including such optical articles (e.g., 101, 200, 300, 470, 480, 490) and eyewear devices (e.g., 130, 400) may provide versatility for multiple users while still being able to be customized for each user's prescription lens needs.

[0114] The foregoing disclosed optical systems, optical articles, and / or eyewear devices may be designed and configured as computer files stored on a computer-readable medium. Some or all of these files may be provided to a manufacturing process for manufacturing electro-optical systems, optical articles, and / or eyewear devices based on such files. Figure 5 An example of a system 500 for manufacturing an optical system, an optical article, and / or an eyewear device is depicted.

[0115] Optical device information 502 (e.g., optical system information, optical article information, and / or eyewear device information) is received at a research / design computer 506. The optical device information 502 can include design information representing at least one physical characteristic of an optical device (e.g., an optical system, an optical article, and / or an eyewear device) (such as optical system 100, optical article 101, 200, 300, 470, 480, 490, or eyewear device 130, 400). For example, the optical device information 502 can include measurements of one or more of the optical articles 101, 200, 300, 470, 480, 490 (e.g., optical components, attachment devices, support structures, extensions, flanges, etc.) or the eyewear devices 130, 400 (e.g., frames, attachment devices, nose pads, temple arms, bridge pieces, etc.), and these measurements are input via a user interface 504 coupled to the research / design computer 506. The research / design computer 506 includes a processor 508 coupled to a computer-readable medium (e.g., a computer-readable storage device) (such as a memory 510), such as one or more processing cores. The memory 510 can store computer-readable instructions that are executable to cause the processor 508 to transform the optical device information 502 into a design file 512. The design file 512 can include information indicating the design of an optical device (e.g., one or more optical devices or components), such as measurements of one or more of the optical articles 101, 200, 300, 470, 480, 490 (e.g., optical components, attachment devices, support structures, extensions, flanges, etc.) or the eyewear devices 130, 400 (e.g., frames, attachment devices, nose pads, temple arms, bridge pieces, etc.). The design file 512 can be in a format that can be used by other systems to perform manufacturing, as further described herein.

[0116] The design file 512 is provided to the manufacturing computer 514 to control manufacturing equipment during the manufacturing process of the material 520. The manufacturing computer 514 includes a processor 516 (e.g., one or more processors) (such as one or more processing cores) and a memory 518. The memory 518 may include executable instructions, such as computer-readable instructions or processor-readable instructions executable by a computer (such as the processor 516). The executable instructions may enable the processor 516 to control the manufacturing equipment during the manufacturing process of the material 520, such as by sending one or more control signals or data. In some implementations, the manufacturing system (e.g., an automated system that performs the manufacturing process) may have a distributed architecture. For example, a high-level system (e.g., the processor 516) may issue instructions to be executed by the controllers of one or more low-level systems (e.g., individual parts of the manufacturing equipment). The low-level systems may receive the instructions, issue sub-commands to lower-level modules or process tools, and may transmit status back to the high-level system. Thus, multiple processors (e.g., the processor 516 and one or more controllers) may be distributed in the manufacturing system.

[0117] The manufacturing equipment includes a first manufacturing equipment 522, a second manufacturing equipment 524, and an assembly equipment 526. The first manufacturing equipment 522 is configured to form an optical component, such as an optical component (e.g., 102, 202, 202a, 202b, 302, 302a) formed from the material 520 (such as a sheet). The optical component may be formed by drilling, cutting, etching, milling, molding, injection, etc. The second manufacturing equipment 524 is configured to form an eyewear device (e.g., 130, 400) from the material 520. The eyewear device may be formed by drilling, cutting, etching, milling, molding, injection, etc.

[0118] The assembly equipment 526 is configured to assemble the manufactured parts into one or more devices. For example, the optical component may be assembled with one or more attachment devices to form an optical article. As another example, an optical article including an optical component may be coupled to an eyewear device.

[0119] Manufacturing operations are performed on the material 520 to form one or more optical devices 528 (e.g., one or more optical devices - optical articles, eyewear devices, or both). For example, one or more optical devices 528 may include or correspond to optical articles 101, 200, 300, 470, 480, 490 (e.g., optical components, attachment devices, support structures, extensions, flanges, etc.) or eyewear devices 130, 400.

[0120] System 500 enables the manufacture of one or more optical devices as described herein. For example, the one or more optical devices can include an eyewear device and / or one or more optical articles (e.g., one or more prescription attachments) that can be selectively coupled / decoupled to / from the eyewear device. Accordingly, system 500 can advantageously form one or more optical devices to provide versatility to the eyewear device such that a user does not need to own both prescription and non-prescription forms of the eyewear device, which can beneficially reduce the cost to the user.

[0121] Reference Figure 6 , shows an example of a method of forming one or more optical devices. Method 600 can be performed by one or more components of system 500 (as non-limiting examples, optical articles 101, 200, 300, 470, 480, 490 (e.g., optical members, attachment devices, support structures, extensions, flanges, etc.) or eyewear device 130, 400).

[0122] Method 600 includes forming, at 602, an optical member having opposing first and second lens surfaces. The optical member can include or correspond to optical articles 101, 200, 300, 470, 480, 490. In some implementations, the optical member is a single optical member of an optical article. Additionally or alternatively, forming the optical member can include molding, casting, surface machining, milling, edging, laser etching, grinding, etc. or a combination thereof, as illustrative and non-limiting examples.

[0123] Method 600 further includes coupling, at 604, a magnet to the optical member, the magnet being configured to couple to a frame of the eyewear device. For example, the magnet can include or correspond to an attachment device (e.g., 104, 204, 304). In some implementations, the magnet can be attached to a first side of the optical member. By way of illustration, the magnet can be coupled (e.g., attached and / or implanted) near or adjacent to a perimeter of the first side of the optical member.

[0124] Method 600 includes providing, at 606, a mounting bracket coupled to the optical member, the mounting bracket being configured to couple to a frame of the eyewear device. For example, the mounting bracket can include or correspond to (e.g., 104, 204, 304). In some implementations, providing a mounting bracket coupled to the optical member includes machining the mounting bracket. By way of illustration, the mounting bracket can be machined by milling or edging a side surface of the optical member.

[0125] Although method 600 has been described as including coupling magnets (e.g., at 604) and providing mounting brackets (e.g., at 604), one or both of them may optionally be performed or not performed. In such an implementation, method 600 may include coupling one or more attachment devices to the optical member. The one or more attachment devices may include or correspond to magnets, mounting brackets, adhesives, cavities, protrusions, a portion of Velcro (e.g., hooks and / or loops), friction devices, adhesives, male / female connectors (e.g., protrusions or recesses), other fasteners (e.g., pins, hooks and loops, etc.), the like, or combinations thereof.

[0126] In some implants, forming the optical member at 602 includes forming an optical member that includes a first end, a second end, a first lens surface, a second lens surface, and a side surface. Additionally or alternatively, forming the optical member at 602 may include forming a receiving sheet and forming the optical member from the sheet.

[0127] In an implementation of method 600, forming the optical member may include machining at least a portion of the optical member. By way of illustration, machining may include edging, milling, laser etching, etc. In some such implementations, prior to forming the optical member, method 600 may include tracing the frame of the eye wear device (e.g., 432) or receiving design information (e.g., dimensional data) of the frame of the eye wear device or design information corresponding to the frame of the eye wear device.

[0128] In some implementations, method 600 may include forming a support structure. The support structure may include or correspond to 260. Forming the support structure may include forming an annulus, such as support structure 260 (e.g., the annulus). In some such implementations, method 600 may further include forming a channel in a side surface of the optical member. The side surface may be positioned between a first lens surface and a second lens surface. The channel may include or correspond to channel 218. In some such implementations, method 600 may include positioning at least a portion of the support structure within the channel. The optical member may be coupled to a magnet, a mounting bracket, or both via the support structure. For example, coupling the magnet may include coupling the support structure to the optical member. Additionally or alternatively, providing a mounting bracket may couple the support structure including the mounting bracket to the optical member. In some implementations, a first support structure may be coupled to the optical member and may be separated from the optical member. After the first support structure is separated from the optical member, a second support structure may be coupled to the optical material. The first support structure corresponds to a first eye-wear device and may include one or more attachment devices configured to couple with corresponding attachment devices of the first eye-wear device. The first eye-wear device may be different from the second eye-wear device. The second support structure corresponds to a second eye-wear device and may include one or more attachment devices configured to couple with corresponding attachment devices of the second eye-wear device.

[0129] In some implementations of method 600, forming the optical member further includes forming a first portion that includes a lens having a first lens surface and a second lens surface. In some such implementations, forming the optical member further includes forming a second portion extending from a side surface of the first portion. The side surface may be positioned between the first lens surface and the second lens surface. In some implementations, the first portion and the second portion are formed using a milling machine. In some such implementations, the optical member may be coupled to a magnet, a mounting bracket, or both via the second portion. By way of illustration, the magnet may be coupled to the second portion, the mounting bracket may be included in the second portion, or both may be performed. Additionally or alternatively, providing a mounting bracket may include forming the mounting bracket from a received sheet that forms the optical member.

[0130] In some implementations, method 600 may optionally or alternatively include forming a frame of an eye-wear device and / or forming an eye-wear device. For example, forming one or more parts of an eye-wear device may not include forming an optical article and / or may not include forming an optical component. The frame may have a first side and a second side (e.g., a user-facing side). In some implementations, forming the frame may include forming or coupling one or more attachment devices. For example, forming or coupling one or more attachment devices may include: coupling a magnet to the second side, forming a cavity, or both. The magnet of the frame may be configured to couple with a magnet of the optical article. The cavity may be configured to receive at least a portion of a mounting bracket of the optical article. In some such implementations, the cavity may be defined by the frame of the eye-wear device. Additionally or alternatively, the cavity may be defined by a nose pad of the frame. In some such implementations, the nose pad is coupled to the frame or is integral with the frame.

[0131] Accordingly, method 600 enables the fabrication of one or more components of an optical system. For example, method 600 enables the fabrication of an optical component that is removably coupled to a frame of an eye-wear device such that a single optical component covers a corresponding lens of the eye-wear device. Fabrication of such an optical component may allow for the use of standard lens fabrication techniques to fabricate the optical article. Additionally, the optical component may be lightweight, quick and simple to assemble, and provide customization for different users and / or different eye-wear devices. For example, the optical component may be customized to correspond to a particular vision prescription of a user and / or the type of frame of an eye-wear device. Accordingly, the optical component is independent for each eye of a user and can easily manage very different prescriptions between a user's two eyes.

[0132] The foregoing specification and examples provide a complete description of the structure and use of illustrative implementations. Although certain implementations have been described above with a certain degree of particularity or with reference to one or more individual implementations, many changes may be made by those skilled in the art to the disclosed implementations without departing from the scope of the invention. Thus, the various illustrative implementations of the methods and systems are not intended to be limited to the particular forms disclosed. Instead, they include all modifications and alternatives falling within the scope of the claims, and implementations other than those shown may include some or all of the features of the depicted implementations. For example, an element may be omitted or combined into an integrated structure and / or a connection may be substituted.
