Abstract
Description
[Technical Field]
[0001] This application claims priority to U.S. Provisional Application No. 62 / 210,024, filed August 26, 2015, the entire disclosure of which is incorporated herein by reference.
[0002] The present invention relates generally to corrective lenses for use in eyewear, such as eyeglasses, protective eyewear, goggles, etc. More particularly, the disclosed systems and methods relate to lenses having a first portion forming a shield or periphery of optically correct material and at least one protrusion permanently disposed on the first portion to form the corrective lens. As configured above, the device allows the periphery of the first portion of the lens to form a unitary structure suitable for engagement with an eyewear frame, goggle, or other lens frame. [Background technology]
[0003] For hundreds of years, people with vision problems have relied on corrective eyewear. Typically, these vision problems are due to physical characteristics of the person's eyes that require corrective lenses. To this day, such corrective lenses have been provided to users in need. The basic nature of lens polishing to refocus the image captured by the user's eyes in a manner that provides clearer vision on the receptor back surface of the eye has advanced to correct problems other than myopia or hyperopia. However, the basic premise of placing lenses in front of the user's eyes to refocus incoming light still exists today.
[0004] The constructional properties of corrective lenses may not be satisfactory, especially in combination with safety or protective eyewear. For example, corrective lenses for users with high hyperopia who require very thick lenses for vision correction are not well suited for use with protective eyewear such as goggles. Furthermore, the periphery of such thick lenses limits their engagement with eyeglass frames.
[0005] Additionally, problems arise when individuals with nearsightedness, farsightedness, or other vision problems attempt to wear protective goggles, such as those in the military who wear goggles, or those who wear sports goggles for activities such as skiing, motorcycle riding, etc. The problems with corrective lenses discussed above also pose problems for individuals whose jobs require them to wear safety goggles.
[0006] In the past, users of such eyeglasses had no choice but to fit their eyeglasses into the gaps of goggles or safety glasses to protect their eyes. In this combination, the user must view their surroundings through both the goggle lenses and their own lenses, which are positioned between the goggle lenses and their face. This can result in poor visibility due to fogging, glare caused by the interaction of spaced reflective surfaces, image shadows caused by spaced lenses, or other problems caused by the interaction of at least one goggle lens with a spaced eyeglass lens.
[0007] The prior art has provided solutions to some of the above-mentioned problems. For example, U.S. Patent No. 6,299,949 (Quintana) is progressive in its concept of providing an integrated corrective lens and a panoramic or occluding lens, but the disclosed integrated structure leaves room for improvement. While U.S. Patent No. 6,299,949 discloses a novel concept for forming an ophthalmic lens using two protrusions extending from one side of a first panoramic lens, it does not address the risk of cracking along the periphery of the protrusions at their intersection with the front panoramic lens. Furthermore, reflections of light entering through the sidewalls of the protrusions and adjacent their intersection with the front panoramic lens, as disclosed in U.S. Patent No. 6,299,949, can cause refractive properties such as coloration of light that can be annoying to users. Furthermore, when used in goggles that form a sealed cavity in front of the user's face, the variable thickness of the panoramic lens with the protrusions or its occluding region can cause thermal problems by retaining heat in the thicker regions during formation. Furthermore, there is no prior art disclosure of how to polish the small protrusions on a curved panoramic shield to the required quality to correct the wearer's vision.
[0008] Therefore, there remains a need for a corrective lens that can be formed on the surface of a thin panoramic lens, where the intersection of the periphery of the protruding material from which the ophthalmic lens is formed and the planar front panoramic lens is configured to prevent cracking and fatigue failure due to age and temperature differences. The apparatus provides a geometry that can be used to form single lenses for eyewear, dual lens configurations for protective eyewear and sports / protective goggle devices, and horizontal and vertical progressive lenses. Furthermore, instead of a large, highly curved panoramic lens surrounding the protrusion, the apparatus and method provide a protrusion on the front panoramic lens that can be machined into a corrective lens using conventional lens grinding machinery.
[0009] The foregoing examples of related art and associated limitations are intended to be illustrative and non-exclusive, and are not intended to imply any limitations on the inventions described herein and in the claims. Various limitations of the relevant prior art will become apparent to those skilled in the art upon reading and understanding the following description and accompanying drawings. [Prior art documents] [Patent documents]
[0010] [Patent Document 1] U.S. Patent No. 8,814,349 Summary of the Invention [Problem to be solved by the invention]
[0011] It is an object of the present invention to provide a first curved or panoramic lens monolithic structure in which at least one cuttable protrusion is formed on the ophthalmic lens.
[0012] Another object of the present invention is to provide a one-piece structure in which the first lens on which the protrusion is formed surrounds the protrusion with a thin cross-section of optical material that can fit into the frame, thereby preventing the user from being prescribed a thick lens.
[0013] Another object of the present invention is to eliminate or at least minimize the possibility of cracks occurring in thin anterior or panoramic lenses at the intersection of the outer peripheral sidewall of the protrusion and the portion of the panoramic lens where the protrusion is formed.
[0014] Another object of the present invention is to form protrusions on the surface of large curved lenses that can be machined using conventional lens polishing machines, regardless of the large, curved first lens portion that surrounds the protrusions.
[0015] Another object of the present invention is to provide a protrusion formed in one piece with a surrounding panoramic primary lens that is shaped to be cut into horizontal and vertical progressive lenses.
[0016] These and other objects, features, advantages, and advantages of the lens invention and system of the present invention over the prior art that will become apparent from the following description are achieved by the improvements described in this specification and the following detailed description, which fully disclose the invention but are not intended to be limiting in any way. [Means for solving the problem]
[0017] The present invention is a monolithically formed lens characterized by a first lens portion formed in a generally concave panoramic shape and having a plurality of protrusions on a rear surface thereof, the protrusions being permanently connected to a first surface of the first lens portion and having a shape defined by a raised peripheral edge, the cross-sectional thickness of the first lens portion curving around and surrounding the protrusions being less than the cross-sectional thickness of the region bounded by the outer peripheries of the protrusions rising from the interior or first side of the first lens portion.
[0018] In a preferred embodiment of the device, the radius of the first lens portion or shield may be slightly different to better accommodate the central portion of the shield where the protrusions are located, further reducing distortion. For example, the radius of the first lens portion or shield may be 75 mm, which is the typical radius of the front surface of the shield or first lens portion. However, the central portion where the protrusions extend may be 65 mm (thinner). This slightly thinner arc in the central portion has been found to increase the range of prescribable correction. However, the difference in radius is not noticeable to the naked eye, and the first portion or shield generally retains its original shape, providing aesthetics and compatibility with conventional frames and goggle housings.
[0019] This first lens portion is optically correct over its entire surface, has thinner peripheral regions on either side of the central portion that are optically correct, and has a very thin cross-section so that it can fit within an eyeglass frame or goggles, but is also suitable for fitting over the temples to form a shield.
[0020] In all embodiments of the device according to the invention, the intersection of the outer periphery of the sidewall defining the shape of the protrusion used to form the lens and the first surface of the first lens portion is preferably not an intersection of two perpendicular planes, nor an intersection consisting of a straight line extending from the sidewall surface of the protrusion.
[0021] In all embodiments of the device according to the invention, the intersection of the outer peripheral sidewall of the protrusion that defines the shape of the protrusion is preferably formed such that the line extending through the sidewall from the intersection with the first face of the first lens portion is non-linear, and the portion of the sidewall that extends to the edge of the machinable surface of the protrusion changes direction relative to the remainder of the sidewall.
[0022] In all embodiments of the device according to the invention, the one or more protrusions engage the surrounding optically correct panoramic lens so that they are permanently connected to each other, forming a unitary structure with minimal, if any, optical distortion, and the connection with the at least one protrusion is preferably achieved by molding the protrusion and the first lens portion or shield defining the panoramic lens together.
[0023] When forming a unitary structure, the protrusion and first lens portion or shield may be molded as an integral unit, or the protrusion may be co-molded with the first lens portion. When co-molding, the protrusion is pre-formed and then connected to the mold for the first lens portion where the first surface of the protrusion melts and bonds to the protrusion to form the unitary structure.
[0024] As previously mentioned, the intersection between the outer peripheral sidewall of the protrusion and the central portion of the first lens portion is preferably not perpendicular. Therefore, when molding or forming the integrated first lens portion and protrusion structure, the intersection is preferably curved or angled. Furthermore, experiments have shown that this minimizes distortion and light reflection problems, so the angled or curved intersection forming the connection is preferably small in width and protrudes no more than 1 millimeter above the surface of the first lens portion.
[0025] Furthermore, in the case of a goggle or eyeglass frame that includes a curved first lens portion or shield with multiple protrusions that engage the frame, a polarizing layer may be placed between the material forming the first lens portion and the protrusions that can be machined to form the corrective lenses, thereby polarizing the light reaching the wearer. This may be achieved by layering the first lens portion.
[0026] Additionally, the shape of the protrusion defined by the sidewall intersecting the first surface of the first lens portion may be as described herein or may have any other shape that allows for cutting of the progressive lens for the user, such as a wider diameter adjacent the two ends of the curved first lens portion and narrowing towards the middle, as shown.
[0027] This preferred shape allows a portion of the protrusion to extend near the bridge of the nose and well below the temples and nose. This elongated rectangular shape, with the curved portion extending from the nose to the lower edge, allows the progressive lens to be formed horizontally from the top to the bottom and laterally from the nose to the temples, enabling the formation of a progressive lens that is highly customizable for the user. The peripheral portion of the first lens portion is very thin compared to the integral portion of the protrusion and first lens portion, allowing the resulting lens or shield to be configured to the user.
[0028] Additionally, a preferred example of a removable tool engagement member that may be formed as part of the integral lens is shown. By forming the tool engagement member to extend perpendicularly from the axis of the integral lens at its central portion and engage independently or removably, the removable protrusion member can be used to engage the integral structure with a lens machining device to machine the raised protrusion surface to form a corrective lens. As previously mentioned, this tool engagement and the integral structure of the first lens and protrusion overcomes the problem associated with the prior art in which a large, curved, panoramic first lens portion prevents engagement with a lens grinder in a conventional manner. After at least one protrusion surface has been properly machined into a corrective lens, the protrusion member can be removed by breaking off any frangible portions or cutting off the side edges.
[0029] Finally, the unitary lenses of the present invention are particularly well suited for forming protective eyewear, sports goggles, and the like, since the plurality of raised portions may permanently engage and extend onto the first surface of the first lens portion surrounding the raised portions, providing a goggle with a large, panoramic design having a thin edge, and the unitary construction prevents fogging, etc. Additionally, as previously mentioned, a wafer or layer of polarizing film may be disposed between the lenses or within the protrusions that are preformed and then co-molded to the first lens portion, thereby providing the user with polarized eyewear for severe glare conditions.
[0030] In all embodiments, the first lens portion and at least one protrusion surrounding the mating protrusion may both be formed from polycarbonate plastic or other optically suitable polymeric or plastic material such as a monomeric plastic or a "high index" plastic.
[0031] In view of the above, before describing in detail at least one preferred embodiment of eyewear according to the present invention, it is to be understood that the present invention is not limited in its application to the detailed construction and arrangement of steps set forth in the following description or illustrated drawings. Those skilled in the art will recognize, upon reading this disclosure, that the integrated lenses according to the present invention described herein are capable of other embodiments and of being practiced and carried out in various ways. Furthermore, the terminology and terminology used herein is for the purpose of description and not of limitation.
[0032] Thus, it will be appreciated that those skilled in the art will be readily able to design and implement the disclosed system and eyewear device by utilizing the concepts underlying the present disclosure as a foundation. It is therefore important to understand that the claims of this application are intended to cover equivalent structures and methods as long as they do not depart from the spirit and scope of the present invention.

DETAILED DESCRIPTION OF THE INVENTION
[0034] Other aspects of the present invention can be readily understood by reference to the accompanying drawings and the following detailed description, both of which are not intended to be limiting.
[0035] Referring to Figures 1-19, in which like structure is designated by like numerals, Figure 1 illustrates an embodiment of a device 10 having a unitary lens comprising a first lens portion 12 having a first surface 14 and at least one, and as shown, preferably a plurality of, protrusions or projections 16 extending from the first surface 14. The projections 16 have a shape defined by a periphery formed by sidewalls 18 that extend away from an intersection 20 with the first surface 14 of the first lens portion 12 at a first end of the sidewall 18. The sidewalls 18 of each of the projections 16 extend to a tip at an intersection with an edge of a protruding surface 22 formed within the periphery defined by the sidewalls 18. The protruding surfaces 22 are suitable for forming an ophthalmic lens for correcting the vision of a user or wearer.
[0036] 1 shows a particularly preferred shape of the protrusions 16. As shown, the diameter of each of the two protrusions 16 is wider at the portions adjacent to the two ends of the curved first lens portion 12 and is narrower at the end adjacent to the middle portion.
[0037] This preferred shape allows a portion of the protrusion 16 to extend to the bridge of the nose while also extending well below the temples and nose. This elongated rectangular shape curves from the nose side of the protrusion 16 to the lower edge adjacent both ends of the first lens portion 12, allowing the protrusion 16 to be used to form progressive lenses and prescription eyewear. The resulting progressive lenses are highly customizable both horizontally from top to bottom and laterally from the nose to the temples.
[0038] Figure 2 shows the opposite or second side of the first lens portion 12 shown in Figure 1. A novel aspect of the disclosed device 10 is the unitary construction in which an ophthalmic lens is formed on the protrusion 16 that protrudes from the first side 14 of the first lens portion 12, such that when viewed from the second surface 24, the second surface 24 appears unshadowed, even when a filter material is inserted as described below.
[0039] 3 illustrates a perspective view of the device 10 shown in FIG. Each of the illustrated plurality of two protrusions 16 has a shape defined by the perimeter of a sidewall 18 extending from an intersection 20 with the first surface 14 of the first lens portion 12. As illustrated, the cross-sectional thickness of the first lens portion 12 is very thin and surrounds the formed protrusion 16. As previously discussed, the integral structure of the protrusion 16 and first lens portion 12 is formed by integrally molding the protrusion 16 and the lens portion 12, or by co-molding a formed protrusion 16 into a mold for the first lens portion 12 to melt and form the protrusion 16 into the structure of the first lens portion 12.
[0040] 4 is a cross-sectional view of the device of FIGS. 1 and 3, showing the integral structure of the first lens portion 12 and the protrusion 16. The intersection 20 of the sidewall 18, which forms the periphery and defines the shape of the protrusion 16, with the first surface 14 of the first lens portion 12 is preferably non-linear. As previously mentioned, the non-linear intersection 20 of the sidewall 18 with the first surface 14 is of utmost importance. By non-linear, we mean that a line extending along the surface of the sidewall 18 between the raised surface 22 and its connection with the intersection 20 does not intersect a line or plane on the first side of the first lens portion.
[0041] Alternatively, at or adjacent the intersection 20, the surface of the sidewall 18 deviates from a flat or straight surface and has an angled or curved portion in the surface communicating between the sidewall 18 and the first surface 14. While the angled intersection of Figure 4c and the curved intersection of Figure 4a are currently particularly preferred for non-linear communication between the first surface 14 and the sidewall 18, the other shapes of intersections shown in Figures 4b-4d are also examples of non-linear communication of the sidewall 18 at or adjacent the first surface 14.
[0042] FIG. 4 a shows the curved surface at the intersection 20 of the sidewall 18 that defines the shape of the protrusion 16 and the first surface 14 of the first lens portion 12 .
[0043] FIG. 4 b shows the inverted curved surface of the intersection 20 of the sidewall 18 that defines the shape of the protrusion 16 and the first surface 14 of the first lens portion 12 .
[0044] FIG. 4 c shows the beveled surface of the intersection 20 of the sidewall 18 and the first surface 14 of the first lens portion 12 that defines the shape of the protrusion 16 .
[0045] Figure 4d shows the intersection 20 in the shape of a curved relief on the outer peripheral edge of the side wall 18, which extends below the first end of the side wall 18 and, depending on the first surface 14, extends to the outer periphery of the protrusion 1.
[0046] 4a and 4b, an intersection formed by a curved surface extending between the first end of the side wall and the first surface of the first lens portion, an intersection formed by a slanted surface extending between the first end of the side wall and the first surface of the first lens portion, and an intersection formed by a recess extending below the first end of the first side wall 18 and dependent on the first surface 14 of the first lens portion 12. By forming a non-linear intersection as described above, cracks can be prevented.
[0047] FIG. 5 illustrates another embodiment of a one-piece lens construction apparatus 10 according to the present invention. Shown is a curved, panoramic first lens portion 12 and two circular protrusions 16 extending from the first surface 14 of the curved first portion 12 of the lens to be formed. The perimeter intersection 20 of both of the illustrated side walls 18 is preferably non-linear, as previously described. Also shown is a centrally located tool engagement member 28 for operably engaging the first lens portion 12 along a side edge. The tool engagement member may be used with any of the embodiments of the apparatus according to the present invention.
[0048] FIG. 6 is an opposite view of the one-piece lens structure shown in FIG. 5, showing the second side 24 and the tool engagement member 28 centrally located between the two side edges 13 of the first lens portion 12 and extending perpendicular to the horizontal axis extending between the two side edges 13.
[0049] 7 shows a perspective view of this configuration. As shown, the tool engagement member 28 is centrally located between the two ends 13 of the first lens portion 12 and extends generally perpendicular to an axis 17 that extends across the first lens portion 12 between the ends or temple ends of the first lens portion 12. As previously mentioned, the tool engagement member 28 is suitable for engagement with conventional eyeglass grinding machines that are incompatible with or unable to engage when forming goggle lenses.
[0050] 8 shows a sports or protective goggle embodiment 33 of the device 10 according to the invention. The arrangement shown in FIGS. 9 to 12 can be engaged with the goggle frame shown in FIG.
[0051] FIG. 9 shows a first lens portion 12 having two protrusions 16 and a second lens 31 that is adjacently engaged with a gap on the second surface 24 of the first lens portion 12 to engage the goggles of FIG. 8.
[0052] Figure 10 shows an embodiment of the device 10 similar to that shown in Figure 9 and engageable within the goggle frame 33 shown in Figure 8, for example. In this figure, the cavity-forming second lens 31 is positioned adjacent to the lens-machinable raised surface 22 of the protrusion 16.
[0053] Figure 11 shows another embodiment of goggles or protective eyewear that is configured to minimize fogging in the same manner as Figures 9, 10, and 12. As shown, a mating second lens 31 having a protrusion 35 is configured and engageable such that the protrusion 35 fits adjacent to and fills the gap with the sidewall 18 of the formed protrusion 16 of the first lens 12.
[0054] FIG. 11 shows another embodiment of the device that fits onto goggles that minimize fogging in the same manner as FIGS. 9, 10, and 12, and a fitting lens having a protrusion configured to fit adjacent to the sidewall of the formed protrusion of the first lens.
[0055] 12 shows an embodiment of the device that, like other embodiments of the invention, forms a unitary lens structure consisting of a first lens portion 12 and a protrusion 16. This embodiment of the device is well suited for engagement with an eyeglass frame, as the thinner cross-section of the first lens portion 12 surrounding the thicker area where the protrusion 16 rises provides a better fit to the frame.
[0056] 12, showing the peripheral intersection 20 of the sidewall 18 and the first surface 14 of the first lens portion 12. As shown, the sidewall 18 defines an elliptical protrusion 16 extending from the first surface 14 of the first lens portion 12.
[0057] FIG. 14 is a cross-sectional view of the device shown in FIGS. 12 and 13, illustrating a preferred non-linear intersection 20 between the side wall 18 and the first surface 14 of the first lens portion 12, which is preferred in all embodiments of the device according to the present invention.
[0058] 15a-15d show various non-linear shapes for the intersection 20 between the sidewall 18 and the first surface 14 of the first lens portion 12. Those shown are highly preferred to avoid linear intersections that are prone to cracking.
[0059] Figure 16 shows a one-piece lens device 10 formed to engage with an eyeglass frame, with a thicker protrusion 16 surrounded by a thinner first lens portion 12, allowing for vision prescriptions requiring thicker lenses and also allowing the formed lens device 10 to engage with more fashionable eyewear when the wearer must use such thick lenses for vision correction. Figure 17 shows an embodiment similar to that of the device 10 shown in Figure 16, but with a rectangular panoramic first lens portion 12.
[0060] Figures 18 and 19 illustrate when it may be desirable or necessary to filter the field of view in any of the embodiments of the device 10. Figure 18 illustrates the integrated lens device 10 with a polarizing or other filtering layer 36 engaged between the protrusion 16 and the second side 24 of the first lens portion 12. In Figure 19, the polarizing or other filtering layer 36 is disposed across the first lens portion 12, between the first surface 14 and the second surface 24 of the first lens portion 12.
[0061] While all of the essential characteristics and features of the software-enabled employment management and verification system have been disclosed and described herein with reference to specific embodiments, it is clear that the above disclosure contemplates any modifications, variations, and substitutions, and that features or steps of the present invention may be used without the corresponding use of other features or steps without departing from the scope of the invention as described. It is also understood that those skilled in the art may make various substitutions, changes, and modifications without departing from the spirit or scope of the invention.
