Description

Technical Field

[0001] This manual relates to the field of wearable devices, and in particular to a pair of glasses. Background Technology

[0002] Augmented Reality (AR) glasses overlay virtual information onto a user's field of vision, enhancing their perception of the real world. Waveguide technology is commonly used in AR, but its high cost and low optical efficiency have hindered its large-scale industrial adoption. Non-waveguide technologies can directly use curved lenses to reflect images, but this method suffers from severe optical distortion due to curvature, requiring correction through optical design. This results in extremely complex and bulky optical mechanisms, and the relative positions and shapes of the optical engine, lenses, and the human eye must be highly stable. Any slight deformation or displacement can lead to image distortion or even defocusing, and the technology is poorly adaptable to users with different head shapes.

[0003] Therefore, it is desirable to provide glasses that can overlay virtual information onto the user's field of vision, adapt to different wearers' interpupillary distances, and have excellent optical performance and comfortable wear. Summary of the Invention

[0004] This specification provides one or more embodiments of eyeglasses, including: a frame, the frame including an eyeglass frame and temples; a light source disposed on the frame; and a planar reflective mirror, the planar reflective mirror being arranged at a distance from the light source, wherein a light beam emitted by the light source is reflected by the planar reflective mirror and enters the wearer's target eye, presenting a virtual image corresponding to the light beam in front of the eyeglasses; wherein the incident angle or incident position of the light beam on the planar reflective mirror is adjustable to adjust the position of the virtual image, ensuring that the light beam can enter the eyes of wearers with different interpupillary distances after reflection, expanding the applicability of the eyeglasses and improving the user experience of the eyeglasses.

[0005] In some embodiments, the glasses further include: a first movable component, the first movable component including a first static component and a first dynamic component, the first static component being fixed relative to the bracket, the first dynamic component being variable in position relative to the first static component, the light source being mounted on the first dynamic component, and the incident angle or incident position of the light beam emitted by the light source being adjusted by changing the position of the first dynamic component relative to the first static component, so as to adjust the position of the virtual image and ensure that the light beam can enter the eyes of wearers with different interpupillary distances after reflection.

[0006] In some embodiments, the first movable component includes a knob and a rotating shaft, the light source is connected to the rotating shaft, the knob is configured to adjust the position of the rotating shaft to adjust the incident position of the light beam, and the rotating shaft is configured to adjust the incident angle of the light beam. The aforementioned first movable component has a simple structure, avoiding excessive weight of the glasses and reducing the wearer's comfort.

[0007] In some embodiments, the glasses further include: a second movable component, the second movable component including a second static component and a second dynamic component, the second static component being fixed relative to the bracket, the second dynamic component being variable in position relative to the second static component, the planar reflective mirror being disposed on the second dynamic component, and the incident angle or incident position of the light beam emitted by the light source being adjusted by changing the position of the second dynamic component relative to the second static component, so as to adjust the position of the virtual image and ensure that the light beam can enter the eyes of wearers with different interpupillary distances after reflection.

[0008] In some embodiments, the light source includes a light source array, which includes multiple light source units, each of which can be addressed independently. The light source is configured to adjust the light emission state of the light source units in different regions of the light source unit array to adjust the incident angle or the incident position of the light beam, thereby avoiding the need for excessive mechanical structures in the glasses and ensuring the stability of the glasses during use.

[0009] In some embodiments, the light source includes an adjustable grating, which is configured to adjust the transmission pattern on the adjustable grating to adjust the incident angle or incident position of the light beam, thereby adjusting the position of the virtual image and ensuring that the light beam can enter the eyes of wearers with different interpupillary distances after reflection.

[0010] In some embodiments, the glasses are further configured to automatically adjust the incident angle or incident position of the light beam based on the wearer's pupil position, thereby reducing the difficulty of operating the glasses and ensuring that the light beam emitted by the light source can enter the pupil area of ​​the wearer's target eye after being reflected by the plane mirror, thus adapting to the use of wearers with different interpupillary distances and improving the adaptability of the glasses.

[0011] In some embodiments, the angle between the center of the virtual image and the visual axis of the target eye is between 0 and 50°. The visual axis of the target eye passes through the center of the target eye and is parallel to the wearer's sagittal axis, so that the virtual image is located in the middle area of ​​the target eye's field of vision, avoiding the need for the target eye to turn too much to see the virtual image and ensuring the wearer's comfort when using glasses.

[0012] In some embodiments, the glasses include a first lens and a second lens, both located on the outer side of the target eye. The planar reflective surface is disposed on the inner surface of the second lens, and the second lens is disposed on the inner side of the first lens. The inner side of the first lens is the side facing the wearer, and the inner surface of the second lens is the side facing the wearer, so as to ensure that the light beam emitted by the light source can enter the wearer's target eye after being reflected by the planar reflective surface.

[0013] In some embodiments, the eyeglasses include a third lens, the planar reflective surface being formed by an array of multiple planar micromirrors on the inner surface of the third lens, each planar micromirror being convex or concave relative to a spacer region surrounding it, wherein the inner surface of the third lens is the side of the third lens facing the wearer, and the spacer region is the area between every two planar micromirrors in the third lens, to ensure that the light beam emitted by the light source can be reflected by the planar reflective surface and enter the wearer's target eye.

[0014] In some embodiments, the eyeglasses include a fourth lens, the inner surface of which has a first planar region, and the outer surface of which has a second planar region. The first planar region and the second planar region are positioned opposite each other, and one of the first planar region and the second planar region constitutes the planar reflective mirror. The inner surface of the fourth lens is the surface of the fourth lens facing the wearer, and the outer surface of the fourth lens is the surface of the fourth lens facing away from the wearer, so as to ensure that the light beam emitted by the light source can enter the wearer's target eye after being reflected by the planar reflective mirror.

[0015] In some embodiments, the first planar region and another of the second planar regions constitute a transmissive mirror, and the reflectivity of the planar reflective mirror is higher than that of the transmissive mirror, thereby ensuring that the wearer can see the virtual image while avoiding any omissions in the external environment seen by the wearer.

[0016] In some embodiments, the eyeglasses further include a fifth lens, which is located on the outer side of the target eye, and the fifth lens is arranged on the outer side of the fourth lens. An air gap is reserved between the fifth lens and the fourth lens. The outer side of the fourth lens is the side of the fourth lens that is away from the wearer. The fifth lens can block the fourth lens to ensure the integrity of the eyeglasses as seen from the outside.

[0017] In some embodiments, the glasses include multiple light sources and multiple planar reflective mirrors. The light beam emitted by each light source is reflected by a planar reflective mirror and enters the wearer's target eye. The virtual images corresponding to the multiple light sources are displayed in different positions or with different content in front of the glasses, so as to increase the number of virtual images within the target eye's field of vision, meet the wearer's different needs, and improve the wearer's user experience.

[0018] In some embodiments, the virtual images corresponding to the beams emitted by the multiple light sources are displayed simultaneously or one or more of them are displayed according to instructions, so as to improve the autonomous control when using the glasses, meet the different needs of the wearer at different times, and improve the wearer's user experience.

[0043] To more clearly illustrate the technical solutions of the embodiments in this specification, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this specification. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0044] It should be understood that the terms “system,” “device,” “unit,” and / or “module” used herein are one way to distinguish different components, elements, parts, sections, or assemblies at different levels. However, if other terms can achieve the same purpose, they may be replaced by other expressions.

[0045] As indicated in this specification and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not specifically refer to the singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of expressly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0046] Flowcharts are used in this specification to illustrate the operations performed by the system according to embodiments of this specification. It should be understood that the preceding or following operations are not necessarily performed in exact order. Instead, the steps can be processed in reverse order or simultaneously. Furthermore, other operations can be added to these processes, or one or more steps can be removed from them.

[0047] It should be noted that in medicine, anatomy, and other fields, the human body can be defined by three basic planes: the sagittal plane, the coronal plane, and the horizontal plane, as well as three basic axes: the sagittal axis, the coronal axis, and the vertical axis. The sagittal plane is a section perpendicular to the ground along the anteroposterior direction of the body (e.g., from the chest to the back), dividing the body into left and right parts. The coronal plane is a section perpendicular to the ground along the lateral direction of the body (e.g., from the left shoulder to the right shoulder), dividing the body into anterior and posterior parts. The horizontal plane is a section parallel to the ground along the vertical direction of the body (e.g., from the top of the head to the soles of the feet), dividing the body into superior and inferior parts. Correspondingly, the sagittal axis is the axis along the anteroposterior direction of the body and perpendicular to the coronal plane; the coronal axis is the axis along the lateral direction of the body and perpendicular to the sagittal plane; and the vertical axis is the axis along the vertical direction of the body and perpendicular to the horizontal plane. The following descriptions of this instruction manual refer to the aforementioned orientations.

[0048] Figure 1 These are exemplary block diagrams of eyeglasses shown according to some embodiments of this specification.

[0049] The glasses 100 can overlay virtual images onto the field of vision of the wearer (hereinafter referred to as "the wearer"). The virtual images can be obtained from an external data source or from one or more components of the glasses 100.

[0050] In some embodiments, such as Figure 1 As shown, the glasses 100 includes a frame 110, a light source 120, a plane mirror 130, and a lens 140.

[0051] The bracket 110 can be used to support the various components in the glasses 100. For example, the bracket 110 can be used to support the light source 120.

[0052] The support 110 may include an eyeglass frame 111 and temples 112. For example, a light source 120 may be disposed on the aforementioned eyeglass frame 111 or temples 112. The support 110 may also include other components. For example, such as... Figure 2A , Figure 2B as well as Figure 2C As shown, the support 110 may also include a nose pad 113.

[0053] Light source 120 is used to emit a light beam containing a virtual image. Light source 120 may include a microdisplay and a lens assembly. The microdisplay may include multiple pixels, and the light beam emitted by these pixels contains the virtual image. The lens assembly may be a combination of a transmissive mirror and a reflective mirror, and can collimate the light emitted by each pixel on the microdisplay into a light beam at a preset angle. For example, the lens assembly can collimate the light emitted by each pixel into a parallel beam (or a nearly parallel beam). The light outlet shape of light source 120 can be circular, rectangular, or other shapes. When the light outlet shape of light source 120 is circular, the diameter of light source 120 can range from 5mm to 10mm. When the light outlet shape of light source 120 is rectangular, the diagonal length of light source 120 can range from 5mm to 10mm. This configuration avoids the virtual image being too small due to the size of light source 120, and also avoids the user's wearing experience being affected by the size of light source 120 being too large.

[0054] The aforementioned light source 120 is mounted on the bracket 110. In some embodiments, the light source 120 is mounted on one of the nose pad 113, the eyeglass frame 111, and the temple 112. Figure 2A , Figure 2B as well as Figure 2C As shown, the light source 120 can be respectively mounted on the nose pad 113, the eyeglass frame 111, and the temple 112. It is understood that when the light source 120 is positioned in different locations, the incident position of the beam emitted by the light source 120 is different. Correspondingly, the position where the virtual image corresponding to the beam is presented in front of the glasses 100 can be the same or different. For example, when multiple light sources 120 are positioned in different locations, the incident angle of the beam emitted by each light source 120 can be adjusted so that multiple light sources 120 present the virtual image corresponding to the beam emitted by each light source 120 at the same position in front of the glasses 100, thereby achieving the superposition of multiple virtual images. Through the aforementioned settings, the wearer can select different positions of the light source 120 as needed, ensuring the wearer's autonomy and improving the user experience.

[0055] In some embodiments, the relative position between the light source 120 and the bracket 110 is not adjustable. For example, the light source 120 may be welded or glued to the bracket 110.

[0056] In some embodiments, the relative position between the light source 120 and the bracket 110 is adjustable. Further details on how to adjust the relative position between the light source 120 and the bracket 110 can be found in the relevant description below.

[0057] The planar reflector 130 is a planar structure capable of reflecting the light beam emitted by the light source 120. The planar reflector 130 can be circular, rectangular, or other shapes.

[0058] In some embodiments, the planar reflective mirror 130 can be a total reflection mirror. The total reflection mirror can be achieved by coating a total reflection film on the inner surface of the spectacle lens 140, wherein the inner surface of the spectacle lens 140 is the surface of the spectacle lens 140 facing the wearer.

[0059] In some embodiments, the planar reflective mirror 130 can also be a semi-transparent and semi-reflective mirror. By setting a semi-transparent and semi-reflective mirror, the wearer can simultaneously see virtual images and real-world scenes in the field of view corresponding to the planar reflective mirror 130, thereby improving the realism of AR display. In some embodiments, the semi-transparent and semi-reflective mirror can be achieved by coating a semi-transparent and semi-reflective film on the inner surface of the eyeglass lens 140.

[0060] The plane mirror 130 can be mounted on the spectacle lens 140 in various ways. For more information on how the plane mirror 130 can be mounted on the spectacle lens 140, please refer to the relevant description below.

[0061] In some embodiments, the planar reflective mirror 130 and the light source 120 are arranged at intervals so that the light beam emitted by the light source 120 can illuminate the planar reflective mirror 130. After being reflected by the planar reflective mirror 130, the light beam enters the wearer's target eye, presenting a virtual image corresponding to the light beam in front of the glasses 100, thereby superimposing the virtual image into the wearer's field of vision. The aforementioned target eye can refer to the eye on the corresponding side of the support 110 where the light source 120 and the planar reflective mirror 130 are located. For example, the target eye can be the wearer's left eye, and correspondingly, the left support 110 is equipped with the light source 120 and the planar reflective mirror 130.

[0062] In some embodiments, the relative position between the planar reflective mirror 130 and the support 110 is not adjustable. For example, the planar reflective mirror 130 may be fixedly mounted on the spectacle lens 140, and the relative position between the spectacle lens 140 and the support 110 is not adjustable.

[0063] In some embodiments, the relative position between the planar reflective mirror 130 and the bracket 110 is adjustable. Further details regarding how the relative position between the planar reflective mirror 130 and the bracket 110 is adjusted can be found in the relevant description below.

[0064] In some embodiments, the incident angle or incident position of the light beam on the planar reflective mirror 130 is adjustable. By adjusting the aforementioned incident angle or incident position, the position of the virtual image can be adjusted to ensure that the light beam emitted by the light source 120 can enter the eyes of wearers with different interpupillary distances after being reflected by the planar reflective mirror 130.

[0065] In some embodiments, the glasses 100 can be configured in various ways to adjust the incident angle or position of the light beam on the planar reflector 130. For example, the incident angle or position of the light beam on the planar reflector 130 can be adjusted by adjusting the relative position between the planar reflector 130 and the support 110. As another example, the incident angle or position of the light beam on the planar reflector 130 can also be adjusted by adjusting the relative position between the light source 120 and the support 110. Yet another example is that the glasses 100 can be configured in other ways to adjust the incident angle or position of the light beam on the planar reflector 130. Further details on how to configure the glasses 100 to adjust the incident angle or position of the light beam on the planar reflector 130 can be found in the relevant description below.

[0066] The wearer can observe the external environment through the lens 140. The lens 140 can be made of transparent optical materials such as glass or resin. The lens 140 can include flat lenses and / or curved lenses (e.g., vision correction lenses). The lens 140 can also be a sunglasses lens, a polarized lens, or a smart photochromic lens, used to block some light and shield from strong light.

[0067] The spectacle lenses 140 can be respectively disposed on the eyeglass frames 111 in front of the wearer's eyes, and the eyeglass frames 111 in front of the wearer's eyes can be provided with one or more spectacle lenses 140. The number and type of spectacle lenses 140 disposed on the eyeglass frames 111 in front of the wearer's eyes can be the same or different.

[0068] It is understood that at least one lens 140 of the eyeglasses 100 is provided with a plane reflective mirror 130. For example, one lens 140 of the eyeglasses 100 is provided with a plane reflective mirror 130. Figure 3 The eyeglasses 100 shown have a first lens 141 on the frame 111 in front of one eye, and a first lens 141 and a second lens 142 on the frame 111 in front of the other eye. For example, each lens 140 on both sides of the eyeglasses 100 has a plane reflective mirror 130. The lens 140 on the side corresponding to the target eye will be described below in this specification.

[0069] In one embodiment, the spectacle lens 140 on the side corresponding to the target eye may include a first lens 141 and a second lens 142.

[0070] In another embodiment, the spectacle lens 140 on the side corresponding to the target eye may include a third lens 143.

[0071] In another embodiment, the spectacle lens 140 on the side corresponding to the target eye may include a fourth lens 144. Further details regarding the fourth lens 144 can be found in the related description below. In this embodiment, in addition to the fourth lens 144, the spectacle lens 140 on the side corresponding to the target eye may also include a fifth lens 145.

[0072] For a more detailed description of the embodiment of the spectacle lens 140 on the side corresponding to the target eye, please refer to the relevant description below this specification.

[0073] In some embodiments, the glasses 100 may also include other structures. For example, the glasses 100 may also include a processing device, which may be used to communicate with an external data source and one or more components in the glasses 100 to adjust the virtual image; the processing device may also be used to control the adjustment of the incident angle or incident position of the light beam on the planar reflective mirror 130.

[0074] Some embodiments of this specification, by setting up glasses 100 with adjustable incident angle or incident position of the light beam, can realize the adjustment of the position of the virtual screen, ensure that the light beam can enter the eyes of wearers with different interpupillary distances after reflection, expand the applicability of glasses 100, and improve the user experience of glasses 100.

[0075] In some embodiments, the angle between the center of the virtual image and the visual axis of the target eye ranges from 0° to 50°. The visual axis of the target eye passes through the center of the target eye and is parallel to the wearer's sagittal axis. Figure 3 As shown, the angle α between the center position P of the virtual image and the visual axis A of the target eye ranges from 0 to 50°. In some embodiments, the angle between the center position of the virtual image and the visual axis of the target eye ranges from 0 to 40°. In some embodiments, the angle between the center position of the virtual image and the visual axis of the target eye ranges from 0 to 30°. Through the aforementioned limitations, the virtual image can be positioned in the central region of the target eye's field of vision, preventing the target eye from needing to turn excessively to see the virtual image, thus ensuring the wearer's comfort when using glasses 100.

[0076] In some embodiments, the glasses 100 may include only a light source 120 and a planar reflective mirror 130. For example... Figure 3 As shown, the glasses 100 includes only a light source 120 and a plane reflective mirror 130. At this time, one of the wearer's eyes is the target eye. The light beam emitted by the light source 120 is reflected by the plane reflective mirror 130 and enters the wearer's target eye. A virtual image can be included within the field of vision of the target eye.

[0077] In some embodiments, the glasses 100 may further include a light source 120 and multiple planar reflective mirrors 130. For example, the glasses 100 may include a light source 120 detachably connected to the support 110 and multiple planar reflective mirrors 130 disposed at different positions. When the light source 120 is disposed at different positions on the support 110, the light beam emitted by the light source 120 is reflected by different planar reflective mirrors 130 and enters the wearer's target eye. At this time, a virtual image may be included within the field of vision of the target eye. When the position of the light source 120 on the support 110 changes, the position of the virtual image within the field of vision of the target eye may change. In some embodiments, multiple planar reflective mirrors 130 at different positions may be disposed on the lens 140 corresponding to the wearer's same eye. In some embodiments, multiple planar reflective mirrors 130 at different positions may also be disposed on the lens 140 corresponding to the wearer's different eyes, and correspondingly, the light source 120 may also be disposed on different sides of the support 110. It is understood that when the position of the light source 120 is changed from one side of the support 110 to the other side, the target eye changes. For example, when the position of the light source 120 is changed from the left bracket 110 to the right bracket 110, the target eye changes from the wearer's left eye to the wearer's right eye. Through the aforementioned settings, the position of the light source 120 can be changed, thereby adjusting the position of the virtual image within the target eye's field of vision to meet different needs of the wearer and improve the wearer's user experience.

[0078] In some embodiments, the glasses 100 may further include multiple light sources 120 and a planar reflective mirror 130. For example, the glasses 100 may include multiple light sources 120 disposed at different positions on the support 110 and a planar reflective mirror 130. The light beams emitted by the multiple light sources 120 at different positions are reflected by the planar reflective mirror 130 and enter the wearer's target eye. At this time, the field of vision of the target eye may include multiple virtual images. Through the aforementioned configuration, the number of virtual images within the field of vision of the target eye is increased to meet the different needs of the wearer and improve the wearer's user experience.

[0079] In some embodiments, the glasses 100 may further include multiple light sources 120 and multiple planar reflective mirrors 130. The light beam emitted by each light source 120 is reflected by a planar reflective mirror 130 and enters the wearer's target eye. Multiple virtual images corresponding to the multiple light sources 120 are displayed in different positions or with different content in front of the glasses 100. For example, the multiple planar reflective mirrors 130 can all be disposed on the lens 140 corresponding to one of the wearer's eyes, and correspondingly, the multiple light sources 120 are disposed on the support 110 on that side. In this case, one of the wearer's eyes is the target eye, and the multiple virtual images corresponding to the multiple light sources 120 are displayed in different positions or with different content within the target eye's field of vision. As another example, the multiple planar reflective mirrors 130 can be disposed on the lenses 140 corresponding to both of the wearer's eyes, and correspondingly, the multiple light sources 120 are disposed on the supports 110 on both sides. In this case, both of the wearer's eyes are the target eyes, and the multiple virtual images corresponding to the multiple light sources 120 are displayed in different positions or with different content within the field of vision of each target eye. Through the aforementioned configuration, the number of virtual images within the target eye's field of vision is increased to meet the wearer's different needs and improve the wearer's user experience.

[0080] In some embodiments, virtual images corresponding to the beams emitted by multiple light sources 120 are displayed simultaneously or, according to instructions, one or more of them are displayed. For example, multiple light sources 120 are configured to be used simultaneously, and correspondingly, virtual images corresponding to the beams emitted by the multiple light sources 120 are displayed simultaneously. As another example, the processing device can accept external control instructions and, according to the aforementioned instructions, control the beams emitted by one or more of the multiple light sources 120, thereby displaying one or more virtual images accordingly. The aforementioned configuration can improve the autonomous controllability of the glasses 100 during use, meet the different needs of the wearer at different times, and enhance the wearer's user experience.

[0081] The following section of this manual explains how to set and adjust the incident angle or incident position of the light beam emitted by the light source 120 on the plane mirror 130.

[0082] In some embodiments, the relative position between the light source 120 and the bracket 110 can be adjusted. By adjusting the relative position between the light source 120 and the bracket 110, the incident angle or incident position of the light beam emitted by the light source 120 on the plane reflecting mirror 130 can be adjusted.

[0083] In some embodiments, the light source 120 may be provided with a plug, and multiple positions of the bracket 110 may be provided with connectors adapted to the aforementioned plug. The light source 120 can be detachably connected to the connectors at multiple positions on the bracket 110 through the aforementioned plug, thereby adjusting the relative position between the light source 120 and the bracket 110.

[0084] In some embodiments, the glasses 100 includes a first movable component 150. The first movable component 150 includes a first static element and a first dynamic element. The first static element is fixed relative to the support 110, and the position of the first dynamic element relative to the first static element is variable. A light source 120 is mounted on the first dynamic element, and the incident angle or incident position of the light beam emitted by the light source 120 on the planar reflecting mirror 130 is adjusted by changing the position of the first dynamic element relative to the first static element.

[0085] For example, the first movable component 150 is a deformable metal (e.g., a nickel-titanium alloy sheet, a copper-based alloy sheet, an iron-based alloy sheet, an aluminum sheet, etc.), the first static component can be the part of the aforementioned deformable metal connected to the bracket 110, and the first dynamic component can be the remaining part of the deformable metal. The user (wearer or operator of the glasses 100) can control the first dynamic component in the deformable metal to deform and adjust the relative position between the light source 120 set on the first dynamic component and the first static component and the bracket 110, so as to adjust the incident angle or incident position of the light beam emitted by the light source 120 on the plane reflecting mirror 130.

[0086] In some embodiments, the first dynamic element includes a knob 151 and a rotating shaft 152, with the light source 120 connected to the rotating shaft 152. The knob 151 is configured to adjust the position of the rotating shaft 152 to adjust the incident position of the light beam, and the rotating shaft 152 is configured to adjust the incident angle of the light beam on the planar reflecting mirror 130. Figure 4 as well as Figure 5 As shown, the first static component may include a fixing component 155, and the first dynamic component may include a knob 151, a rotating shaft 152, a threaded rod 153, and a displacement block 154. The fixing component 155 can be fixed relative to the bracket 110. The threaded rod 153 can be disposed on the fixing component 155 and may have an external thread. The displacement block 154 may have an internal thread and may be threadedly connected to the threaded rod 153. The rotating shaft 152 can be disposed on the displacement block 154. The knob 151 can be disposed at both ends of the threaded rod 153. Rotating the knob 151 can drive the threaded rod 153 to rotate, and through the thread on the threaded rod 153 and the displacement block 154, the displacement block 154 can be driven to move along the extension direction of the threaded rod 153. The movement of the displacement block 154 along the extension direction of the threaded rod 153 can adjust the position of the rotating shaft 152 and the light source 120 disposed on the rotating shaft 152, thereby realizing the adjustment of the incident position of the light beam. The rotating shaft 152 can rotate around its rotation axis C. When the rotating shaft 152 rotates around the rotation axis C, it can drive the light source 120 set on the rotating shaft 152 to rotate around the rotation axis C, thereby adjusting the incident angle of the light beam on the plane reflecting mirror 130.

[0087] This specification describes how the first movable component 150, as described in the foregoing embodiments, can adjust the relative position between the light source 120 and the bracket 110, thereby adjusting the incident angle or incident position of the light beam emitted by the light source 120 on the plane reflecting mirror 130. Furthermore, the structure of the aforementioned first movable component 150 is simple, preventing the glasses 100 from becoming too heavy and reducing the wearer's comfort.

[0088] In some embodiments, the relative position between the planar reflector 130 and the bracket 110 can be adjusted. By adjusting the relative position between the planar reflector 130 and the bracket 110, the incident angle or incident position of the light beam emitted by the light source 120 on the planar reflector 130 can be adjusted.

[0089] In some embodiments, the glasses 100 may include a second movable component. The second movable component includes a second static member and a second dynamic member. The second static member is fixed relative to the support 110, and the position of the second dynamic member relative to the second static member is variable. A planar reflective mirror 130 is disposed on the second dynamic member. The incident angle or incident position of the light beam emitted by the light source 120 on the planar reflective mirror 130 is adjusted by changing the position of the second dynamic member relative to the second static member. For example, similar to the first movable component 150, the second movable component may also be a deformable metal. The user can control the deformation of the deformable metal to adjust the relative position between the planar reflective mirror 130 and the support 110, thereby adjusting the incident angle or incident position of the light beam emitted by the light source 120 on the planar reflective mirror 130. More information about deformable metals can be found in the relevant description above in this specification. For example, similar to the first movable component 150, the second dynamic component may also include a knob and a pivot. The planar reflector 130 is connected to the pivot. The knob is configured to adjust the position of the pivot to adjust the position of the planar reflector 130, thereby adjusting the incident position of the light beam. The pivot is configured to adjust the angle of the planar reflector 130, thereby adjusting the incident angle of the light beam on the planar reflector 130. More information about the knob and pivot can be found in the relevant description above in this specification.

[0090] This specification describes how the second movable component, as described in the foregoing embodiments, can adjust the relative position between the planar reflective mirror 130 and the bracket 110, thereby adjusting the incident angle or incident position of the light beam emitted by the light source 120 on the planar reflective mirror 130. Furthermore, the structure of the aforementioned second movable component is simple, preventing the glasses 100 from becoming too heavy and reducing the wearer's comfort.

[0091] In some embodiments, the light source 120 includes a light source array, which includes multiple light source units, each of which can be individually addressed. The light source is configured to adjust the emission state of the light source units in different regions of the light source unit array to adjust the incident angle or incident position of the light beam. A light source unit is the smallest constituent unit in the light source 120. The light source array is an array composed of multiple light source units. By adjusting the emission state of each light source unit in the light source array, the pattern of the virtual image corresponding to the light beam emitted by the light source 120, the position of the light beam emitted by the light source 120, etc., can be adjusted.

[0092] In some embodiments, the light source array is a micro LED array, and the corresponding light source unit is a micro LED.

[0093] In some embodiments, the light source array is a micro OLED array, and correspondingly, the light source unit is a micro OLED.

[0094] For example, such as Figure 6 as well as Figure 7 As shown, the light source array 121 can include 9*9 light source units, where each light source unit can be addressed independently. A box indicates that the corresponding light source unit does not emit light, and a colored block indicates that the corresponding light source unit emits light. When the light source array 121 consists of... Figure 6 Change to Figure 7 Correspondingly, the position of the light beam emitted by the light source array 121 changes, thereby adjusting the incident angle or incident position of the light beam on the planar reflecting mirror 130. The number and arrangement of the light source units emitting light each time can be fixed or variable. For example, the light source 120 can emit light through a preset light-emitting array 121-n in the light source array 121. Figure 6 as well as Figure 7 As shown, the preset light-emitting arrays 121-n can all be 3*3 light source unit arrays. For example, depending on the virtual image, the light source 120 can adjust the number and arrangement of the light-emitting units in the light source array 121.

[0095] Specifically, when using glasses 100, light can be emitted from only a portion of the light source units in the light source unit array of the microdisplay, and this portion of light can be collimated into a beam by the lens assembly. For example... Figure 8A As shown, when it is necessary to adjust the incident angle or incident position of the light beam on the plane mirror 130, the light source unit emitting the light in the light source unit array of the microdisplay can be adjusted to adjust the exit angle of the light beam, thereby adjusting the incident angle of the light beam on the plane mirror 130. Similarly, the incident position of the light beam can also be adjusted by adjusting the light source unit emitting the light in the light source unit array of the microdisplay to adjust the exit position of the light beam.

[0096] For example, such as Figure 8A As shown, the first preset light-emitting array 121-a is a light source unit that emits light in part of the light source array before adjustment, and the second preset light-emitting array 121-b is a light source unit that emits light in part of the light source array after adjustment. When the light source unit emitting light in the light source array is the first preset light-emitting array 121-a, the incident angle of the first preset light-emitting array 121-a on the plane reflecting mirror 130 is β, the incident position is Q1, and the virtual image presented in front of the glasses 100 is virtual image 1. For ease of description, the incident angle of the light source array on the plane reflecting mirror 130 can be the incident angle of the center position of the light source array on the plane reflecting mirror 130. When the light source unit emitting light in the light source array is adjusted from the first preset light-emitting array 121-a to the second preset light-emitting array 121-b located in the S2 direction of the first preset light-emitting array 121-a, if the S2 direction is on a different side from the direction of the target eye (for example, the S2 direction is on the left and the target eye is on the right), when the change angle of the incident angle of the second preset light-emitting array 121-b on the plane reflecting mirror 130 is γ, and the incident angle of the second preset light-emitting array 121-b on the plane reflecting mirror 130 is γ+β=δ, the incident position corresponding to the second preset light-emitting array 121-b will move towards the S1 direction (the S1 direction is opposite to the S2 direction), and the adjusted incident position is Q2. Q2 is located in the S1 direction of Q1. Correspondingly, the light beam emitted by the second preset light-emitting array 121-b will move along the S1 direction after being reflected on the plane reflecting mirror 130 to the wearer's position, thereby adapting to wearers with different interpupillary distances (for example, adapting to wearers with larger interpupillary distances). Because the incident angle of the second preset light-emitting array 121-b on the plane reflective mirror 130 is increased, the virtual image presented by the second preset light-emitting array 121-b in front of the glasses 100 is virtual image 2. When the distance between the virtual image and the plane reflective mirror 130 is set to be less than x, virtual image 2 is located in the S1 direction of virtual image 1; when the distance between the virtual image and the plane reflective mirror 130 is set to be equal to x, virtual image 2 overlaps with virtual image 1; when the distance between the virtual image and the plane reflective mirror 130 is set to be greater than x, virtual image 2 is located in the S1 direction of virtual image 1 and virtual image 2 is located in the S2 direction of virtual image 1, where x is the distance from the light-emitting position of the light source 120 to the plane reflective mirror 130.

[0097] The formula for calculating the interpupillary distance adjustment range by adjusting the light source units in the light source array is as follows: eyebox=(d+x)(tan(β+γ)-tan(β))

[0098] Wherein, eyebox is the interpupillary distance adjustment range corresponding to the light source unit in the light source array; d is the distance from the wearer's pupil to the plane mirror 130; x is the distance from the light emission position of the light source 120 to the plane mirror 130; β is the initial incident angle of the light beam emitted by the preset light emission array 121-n at one end of the light source array; and γ is the maximum deflection angle of the light beam exiting the light source array. The initial incident angle β can be determined by preset or detection, and γ can be determined based on the relevant settings of the light source array, the preset light emission array 121-n, and the initial incident angle β. For example, as... Figure 8B As shown, when the initial incident angle β is 30°, the maximum field of view F0V1 corresponding to the light source array is 30°, and the field of view FoV2 corresponding to the preset light-emitting array 121-n is 20°. Therefore, the maximum deflection angle γ of the beam exit angle in the light source array is 30° - 20° = 10°. If d+x is 20mm, that is, the sum of the distance from the light-emitting position of the light source 120 to the plane reflecting mirror 130 and the distance from the wearer's pupil to the plane reflecting mirror 130 is 20mm, then according to the aforementioned formula, the interpupillary distance adjustment range eyebox corresponding to the light-emitting unit in the light source array is 5.23mm.

[0099] Some embodiments of this specification adjust the light emission state of the light source units in different regions of the light source array 121, that is, adjust the number and / or position of the light emission of the light source units in the light source array. This can achieve the adjustment of the incident angle or incident position of the light beam on the plane reflecting mirror 130, avoid setting too many mechanical structures in the glasses 100, and ensure the stability of the glasses 100 during use.

[0100] In some embodiments, the FoV of the actual displayed image in the light source array can also be changed. It is understood that displaying an image with different FoV sizes results in different sizes of virtual image perceived by the wearer. Therefore, the FoV can be adjusted to enlarge or reduce the size of the virtual image. For example, the size of the virtual image perceived by the wearer can be reduced by decreasing the FoV, according to the wearer's needs.

[0101] In some embodiments, the light source 120 includes an adjustable grating, configured to adjust the transmission pattern on the adjustable grating to adjust the incident angle or incident position of the light beam on the planar reflective mirror 130. For example, the transmission pattern on the grating can be adjusted by adjusting one or more of the following: grating period, grating tilt angle, grating phase, and grating position, thereby adjusting the incident angle or incident position of the light beam on the planar reflective mirror 130. The aforementioned adjustable grating can be adjusted manually by a user or electrically under the control of a processing device. As another example, the transmission pattern of the grating can also be adjusted so that the grating blocks the light in the propagation path of the light emitted from the microdisplay according to the transmission pattern, allowing only the light beam corresponding to the portion of the transmission pattern to continue propagating, thereby adjusting the incident angle or incident position of the light beam on the planar reflective mirror 130.

[0102] In some embodiments, the glasses 100 can also automatically adjust the incident angle or incident position of the light beam on the plane reflecting mirror 130 based on the wearer's pupil position. For example, the processing device in the glasses 100 can acquire the wearer's pupil position, the position of the light source 120, and the position of the plane reflecting mirror 130, calculate how to adjust the adjustment parameters of the light source 120 and / or the plane reflecting mirror 130 using a preset algorithm, and control the corresponding components to adjust the incident angle or incident position of the light beam on the plane reflecting mirror 130 based on the adjustment parameters, so that most of the reflected light beam can enter the wearer's pupil. The aforementioned wearer's pupil position, the position of the light source 120, and the position of the plane reflecting mirror 130 can be obtained through user input or other means (e.g., automatic detection).

[0103] In some embodiments, the glasses 100 can adjust one or more of the following parameters: the relative position between the light source 120 and the support 110; the relative position between the plane mirror 130 and the support 110; the light emission state of the light source units in different regions of the light source array 121; and the adjustable grating of the light source 120, to adjust the incident angle or incident position of the light beam on the plane mirror 130. For example, the adjustment parameters may include the position coordinates of the light source units in the light source array 121 that need to emit light.

[0104] In some embodiments, the glasses 100 can adjust the incident angle or incident position of the light beam through one or more of the aforementioned settings.

[0105] For example, the glasses 100 may include only a first movable component 150 or a second movable component, and the incident angle or incident position of the light beam on the plane reflecting mirror 130 may be adjusted by the first movable component 150 or the second movable component. Alternatively, the glasses 100 may include both a first movable component 150 and a second movable component, and the incident angle or incident position of the light beam on the plane reflecting mirror 130 may be adjusted by the cooperation of the first movable component 150 and the second movable component.

[0106] In some embodiments of this specification, the glasses 100 can automatically adjust the incident angle or incident position of the light beam on the plane reflecting mirror 130 based on the wearer's pupil position, reducing the difficulty of operating the glasses 100 and ensuring that the light beam emitted by the light source 120 can enter the pupil area of ​​the wearer's target eye after being reflected by the plane reflecting mirror, thereby adapting to the use of wearers with different interpupillary distances and improving the adaptability of the glasses 100.

[0107] The following section of this manual explains how to set up the plane mirror 130.

[0108] It is understandable that the plane reflective mirror 130 can be provided on both sides of the eyeglasses 100, or only on one side of the eyeglasses 100. When the plane reflective mirror 130 is provided on only one side of the eyeglasses 100, the lens 140 on the side of the eyeglasses 100 that is not provided can be set according to the wearer's needs.

[0109] The following description will illustrate one embodiment of the setting of the spectacle lens 140 on the side corresponding to the target eye.

[0110] In one embodiment, the spectacle lens 140 may include a first lens 141 and a second lens 142, both located on the outer side of the target eye. A planar reflective mirror 130 is disposed on the inner surface of the second lens 142, and the second lens 142 is disposed on the inner side of the first lens 141. The inner side of the first lens 141 is the side facing the wearer, and the inner surface of the second lens 142 is the side facing the wearer.

[0111] In this embodiment, the second lens 142 can be arranged at a distance from the first lens 141. For example... Figure 3 As shown, one side of the second lens 142 can be disposed on the nose pad 113 and arranged at a distance from the first lens 141.

[0112] In this embodiment, the second lens 142 can also be directly disposed on the inner surface of the first lens 141. For example... Figure 18 As shown, the second lens 142 can be bonded to the inner surface of the first lens 141 using adhesive 170.

[0113] The width of the second lens 142 is smaller than the width of the first lens 141. The width of the first lens 141 is its dimension along the coronal axis, and the width of the second lens 142 is its dimension along the coronal axis. In this embodiment, the width of the second lens 142 can be greater than 5 mm. For example, the width range of the second lens 142 is 5 mm to 25 mm. Furthermore, the width range of the second lens 142 can be greater than 10 mm. For example, the width range of the second lens 142 is 10 mm to 20 mm. By limiting the width range of the second lens 142, it is possible to avoid the second lens 142 being too wide, affecting the overall weight of the glasses 100 and reducing the wearing comfort of the glasses 100; it is also possible to avoid the second lens 142 being too narrow, resulting in a displayable virtual image that is too small or unable to fully reflect the virtual image. The lens thickness of the second lens 142 ranges from 0.1 mm to 1 mm. The thickness of the second lens 142 is its dimension along the sagittal axis. Furthermore, the thickness of the second lens 142 ranges from 0.3 to 0.8 mm. Even further, the thickness of the second lens 142 ranges from 0.4 mm to 0.6 mm. By limiting the thickness range of the second lens 142, it is possible to prevent the second lens 142 from being too thick, which would reduce the wearing comfort of the glasses 100, and also to prevent the second lens 142 from being too thin, which would make it easily damaged.

[0114] Understandably, when the second lens 142 is bonded to the inner surface of the first lens 141 using adhesive 170, the width of adhesive 170 should be as small as possible while ensuring adhesive strength, to avoid affecting the target eye's field of vision. For example, the width of adhesive 170 can range from 0.01mm to 2mm. Another example is a further range of 0.05mm to 1mm. Yet another example is a further range of 0.1mm to 0.5mm.

[0115] The first lens 141 can be a curved lens or a flat lens. For example, the first lens 141 can be a curved lens for correcting vision.

[0116] The second lens 142 can be a planar lens. By setting the second lens 142 as a planar lens, it can be ensured that after the positions of the light source 120 and the planar reflecting mirror 130 change, the angle of the light beam emitted by the light source 120 after being reflected by the planar reflecting mirror 130 will not be deflected, there will be no optical distortion, and the clarity of the virtual image seen by the wearer will be guaranteed. The second lens 142 can also be a curved lens.

[0117] When the second lens 142 is a planar lens, a planar reflective mirror 130 can be obtained by coating a reflective film (e.g., a semi-transparent and semi-reflective film) on a portion or all of the inner surface of the second lens 142.

[0118] The planar reflecting mirror 130 can be formed by an array of multiple planar micromirrors on the inner surface of the second lens 142. In this case, the second lens 142 can be a planar lens or a curved lens. For more information on how the multiple planar micromirrors on the inner surface of the second lens 142 form the planar reflecting mirror 130, please refer to the description below of how the multiple planar micromirrors on the inner surface of the third lens 143 form the planar reflecting mirror 130.

[0119] In this embodiment, the width of the planar reflective mirror 130 disposed on the inner surface of the second lens 142 is 5mm to 25mm. The width of the planar reflective mirror 130 is its dimension along the coronal axis. In some embodiments, the width of the planar reflective mirror 130 disposed on the inner surface of the second lens 142 is 8mm to 20mm. In some embodiments, the width of the planar reflective mirror 130 disposed on the inner surface of the second lens 142 is 10mm to 15mm. By limiting the width of the planar reflective mirror 130 disposed on the inner surface of the second lens 142 to a suitable range, it is possible to avoid the planar reflective mirror 130 being too small to completely reflect the light beam, and also to avoid the planar reflective mirror 130 being too large, which would affect the wearer's comfort.

[0120] In this embodiment, the transmittance of the planar reflective mirror 130 disposed on the inner surface of the second lens 142 is 50% to 95%. In some embodiments, the transmittance of the planar reflective mirror 130 disposed on the inner surface of the second lens 142 is 60% to 90%. In some embodiments, the transmittance of the planar reflective mirror 130 disposed on the inner surface of the second lens 142 is 70% to 80%. By limiting the transmittance of the planar reflective mirror 130 disposed on the inner surface of the second lens 142 to a suitable range, it is possible to avoid the transmittance being too low and affecting the wearer's observation of the external environment, and it is also possible to avoid the transmittance being too high and affecting the imaging of the virtual image.

[0121] In another embodiment, the spectacle lens 140 includes a third lens 143, and a planar reflective surface 130 is formed by a plurality of planar micromirrors arrayed on the inner surface of the third lens 143. Each planar micromirror 1431 protrudes or is recessed relative to a spacer region 1432 surrounding it. The inner surface of the third lens 143 is the side of the third lens 143 facing the wearer, and the spacer region 1432 is the area between every two planar micromirrors 1431 in the third lens 143. For example, as... Figure 9 The eyeglasses 100 shown include a third lens 143, and a planar reflective mirror 130 is formed by a plurality of planar micromirrors on the inner surface of the third lens 143, each planar micromirror 1431 protruding relative to the spacer region 1432 surrounding the planar micromirror 1431.

[0122] In this embodiment, the planar micromirror 1431 can be a planar mirror or a curved mirror.

[0123] The planar micromirror 1431 can be circular, rectangular, or other shapes. For example, the planar micromirror 1431 can be configured as follows: Figure 10A The circle shown can also be set as follows: Figure 10B as well as Figure 10C The rectangle shown.

[0124] In this embodiment, the distance between adjacent planar micromirrors 1431 is 0.2 mm to 2 mm. In some embodiments, the distance between adjacent planar micromirrors 1431 is 0.3 mm to 1.6 mm. In some embodiments, the distance between adjacent planar micromirrors 1431 is 0.5 mm to 1.2 mm. These limitations prevent the distance between adjacent planar micromirrors 1431 from being too large, which would prevent the reflected light from forming a complete virtual image. They also prevent the distance between adjacent planar micromirrors 1431 from being too small, which would prevent the wearer from observing the external environment through the gap area 1432 between adjacent planar micromirrors 1431.

[0125] In this embodiment, the reflectivity of each planar micromirror 1431 is greater than the reflectivity of the adjacent spacer region 1432, ensuring that the light beam can be reflected on the planar micromirror 1431. For example, the planar micromirror 1431 may be coated with a semi-transparent, semi-reflective film or a total reflection film, while the adjacent spacer region 1432 is uncoated. Alternatively, the planar micromirror 1431 may be coated with a semi-transparent, semi-reflective film or a total reflection film, and the adjacent spacer region 1432 may also be coated with a semi-transparent, semi-reflective film, where the transmittance of the semi-transparent, semi-reflective film on the spacer region 1432 is greater than the transmittance of the film coated on the planar micromirror 1431.

[0126] In this embodiment, the transmittance of the planar micromirror 1431 can be 0–95%. Alternatively, the transmittance can be 0–50%. Or, it can be 0–20%. It is worth noting that the planar micromirror 1431 is small in size, and there is a gap 1432 between adjacent planar micromirrors 1431, allowing the wearer to observe the environment in front of them. Therefore, the smaller the size of the planar micromirror 1431, the less it obstructs the target's field of vision, and the easier it is for the wearer to fill in the parts obscured by the planar micromirrors 1431 through the gap 1432. Correspondingly, the transmittance of the planar micromirror 1431 can be set lower to improve the display effect of the virtual image. For example, when the width of the planar micromirror 1431 is 0.2 mm to 0.5 mm, the transmittance can be 0–20%. For example, when the width of the planar micromirror 1431 is 0.5 to 1 mm, the transmittance of the planar micromirror 1431 can be 20 to 50%. For another example, when the width of the planar micromirror 1431 is 1 to 2 mm, the transmittance of the planar micromirror 1431 can be 50 to 95%.

[0127] This specification will now describe another embodiment of the setting of the spectacle lens 140 on the side corresponding to the target eye.

[0128] In another embodiment, the spectacle lens 140 further includes a fourth lens 144, the inner surface of the fourth lens 144 having a first planar region 1441, the outer surface of the fourth lens 144 having a second planar region 1442, the positions of the first planar region 1441 and the second planar region 1442 corresponding, one of the first planar region 1441 and the second planar region 1442 constituting a planar reflective mirror 130, wherein the inner surface of the fourth lens 144 is the surface of the fourth lens 144 facing the wearer, and the outer surface of the fourth lens 144 is the surface of the fourth lens 144 facing away from the wearer.

[0129] like Figure 11 As shown, the regions of the fourth lens 144 other than the first planar region 1441 and the second planar region 1442 can be curved lenses. When the regions of the fourth lens 144 other than the first planar region 1441 and the second planar region 1442 are curved lenses, the connection between the other regions of the fourth lens 144 and the first planar region 1441 and the second planar region 1442 is a smooth curved transition to avoid optical distortion.

[0130] like Figure 12 As shown, the other regions in the fourth lens 144 besides the first planar region 1441 and the second planar region 1442 can also be planar lenses.

[0131] In this embodiment, a semi-transparent and semi-reflective film is coated on the planar reflective mirror 130. The reflectivity of the aforementioned semi-transparent and semi-reflective film can be 5% to 50%. Further, the reflectivity of the aforementioned semi-transparent and semi-reflective film is 10% to 30%. Even further, the reflectivity of the aforementioned semi-transparent and semi-reflective film is 15% to 25%. Through the aforementioned settings, the planar reflective mirror 130 can reflect the light beam emitted by the light source 120, thereby ensuring the clarity of the virtual image seen by the wearer. At the same time, it can also ensure that the wearer can see the external environment through the planar reflective mirror 130, avoiding any gaps in the external environment seen by the wearer and enhancing the augmented reality experience.

[0132] The areas of the fourth lens 144 other than the first planar area 1441 and the second planar area 1442 may be uncoated or coated with an anti-reflective coating to prevent other areas on the inner surface of the fourth lens 144 from reflecting ambient light into the target eye and causing glare.

[0133] In this embodiment, the other of the first planar region 1441 and the second planar region 1442 can constitute a transmissive mirror, and the reflectivity of the planar reflective mirror 130 is higher than that of the transmissive mirror. For example, as Figure 11 As shown, the first planar region 1441 constitutes the planar reflecting mirror 130, and the second planar region 1442 constitutes the transmitting mirror.

[0134] In this embodiment, an anti-reflective coating may be applied to the transmissive mirror to prevent multiple reflections of the light beam from causing ghosting and to ensure the clarity of the virtual image seen by the wearer.

[0135] In this embodiment, such as Figure 13 As shown, in addition to the fourth lens 144, the spectacle lens 140 may also include a fifth lens 145. Both the fifth lens 145 and the fourth lens 144 are located on the outer side of the target eye, and the fifth lens 145 is arranged on the outer side of the fourth lens 144. An air gap M is reserved between the fifth lens 145 and the fourth lens 144. The outer side of the fourth lens 144 is the side of the fourth lens 144 that is away from the wearer.

[0136] Understandably, when the spectacle lens 140 only includes the fourth lens 144, the first planar region 1441 and the second planar region 1442 are directly visible from the outside, affecting the aesthetics of the spectacle 100. Directly making the other of the first planar region 1441 and the second planar region 1442 a curved surface would cause the first planar region 1441 and the second planar region 1442 to form a convex lens, resulting in distortion of the final virtual image. By placing a fifth lens 145 outside the fourth lens 144, the fourth lens 144 can be obscured, ensuring the integrity of the spectacle lens as seen from the outside. Simultaneously, it can prevent the first planar region 1441 and the second planar region 1442 from forming a convex lens and causing distortion of the virtual image.

[0137] In this embodiment, the reflectivity of the fifth lens 145 can be reduced, for example, by coating the fifth lens 145 with an anti-reflection film to avoid ghosting caused by multiple reflections of the light beam. In this embodiment, the absorptivity of the fifth lens 145 can also be increased, for example, by tinting the fifth lens 145 to increase its absorptivity and prevent light leakage when the light beam illuminates the fourth lens 144. The fifth lens 145 can be coated with an anti-reflection film and tinted simultaneously to meet different needs. It is worth noting that when light passes through a lens (e.g., the fifth lens 145), the lens can transmit, absorb, and reflect the aforementioned light; correspondingly, the sum of the transmittance, absorptivity, and reflectivity of each lens is 1. Therefore, the settings of the fifth lens 145 can be adjusted based on the application requirements of the glasses 100 in different scenarios. For example, when it is necessary to reduce light leakage in the glasses 100, the transmittance of the fifth lens 145 needs to be relatively reduced; correspondingly, the absorptivity and / or reflectivity of the fifth lens 145 can be further increased by adjusting at least one of the tinting or coating settings. For example, when it is necessary to improve the clarity of the external environment when the wearer uses glasses 100, it is necessary to relatively increase the transmittance of the fifth lens 145. Correspondingly, the absorption rate and / or reflectance of the fifth lens 145 can be further reduced by adjusting at least one of the settings of dyeing and coating.

[0138] The fifth lens 145 can be a curved lens. For example, the fifth lens 145 can be a vision-correcting lens, which, when the wearer observes the external environment through the fifth lens 145, can correct the vision of the target eye. In some embodiments, the fifth lens 145 can also be a planar lens.

[0139] In this embodiment, the size range of the air gap M can be 0 to 0.5 mm. In some embodiments, the size range of the air gap M can be 0.02 to 0.3 mm. In some embodiments, the size range of the air gap M can be 0.05 to 0.2 mm. By limiting the size range of the air gap M, it is possible to avoid the air gap M being too large, causing the lens 140 to be too thick and heavy, affecting wearing comfort; it is also possible to avoid the air gap M being too small, causing the fifth lens 145 to rub against the fourth lens 144 and resulting in damage.

[0140] In this embodiment, in addition to the fifth lens 145 and the fourth lens 144, the spectacle lens 140 may also include other lenses. For example... Figure 14 As shown, in addition to the fifth lens 145 and the fourth lens 144, the spectacle lens 140 may also include a sixth lens 146. The aforementioned sixth lens 146 can be disposed inside the fourth lens 144, with an air gap reserved between the sixth lens 146 and the fourth lens 144. The inside of the fourth lens 144 is the side of the fourth lens 144 closest to the wearer. This arrangement prevents damage to the fourth lens 144 from affecting the display effect of the virtual image. Similar to the fifth lens 145, the sixth lens 146 can also be a curved lens or a flat lens. For example, both the fifth lens 145 and the sixth lens 146 can be vision-correcting lenses. Correspondingly, when the wearer views the virtual image through the sixth lens 146, the sixth lens 146 can correct the vision of the target eye. By setting both the fifth lens 145 and the sixth lens 146 as vision-correcting lenses, optical correction can be performed on the target eye while the wearer observes the external environment and the virtual image, ensuring that the wearer can clearly see the external environment and the virtual image.

[0141] In the aforementioned embodiments of the spectacle lens 140 configuration corresponding to each target eye, when the spectacle lens 140 includes a double-layer lens, the thickness of each layer of the spectacle lens 140 can range from 0.3mm to 2mm. When the spectacle lens 140 includes three or more layers of lenses, the thickness of each layer of the spectacle lens 140 can range from 0.1mm to 1mm. This configuration avoids the spectacle lens 140 being too thin and easily damaged, and also avoids the spectacle lens 140 being too thick and heavy, which would affect wearing comfort.

[0142] In the aforementioned embodiments of the spectacle lens 140 configuration corresponding to each target eye, when the spectacle lens 140 includes multiple lenses, at least a portion of the multiple lenses are peripherally connected. For example, at least a portion of the fourth lens 144 and the fifth lens 145 are peripherally connected. When the multiple lenses are peripherally connected, the air gaps between the multiple lenses can be filled with dry air free of moisture or inert gases such as nitrogen or argon. When the multiple lenses are partially peripherally connected, microchannels can be created between the air gaps between the multiple lenses and the external atmospheric environment to allow for free airflow.

[0143] When the spectacle lens 140 includes multiple lenses, the multiple lenses can be encapsulated in various ways.

[0144] For example, such as Figure 13 as well as Figure 15 As shown, the periphery of the fourth lens 144 and the fifth lens 145 can be bonded together with adhesive 170. The adhesive 170 can be set at the outer contour edge between the fourth lens 144 and the fifth lens 145. Through the aforementioned setting, multi-layer lenses can be easily assembled, and the balance between the air gap between the multi-layer lenses and the external air pressure can be maintained to avoid lens deformation.

[0145] For example, such as Figure 16 As shown, most of the area between the fourth lens 144 and the fifth lens 145 can be bonded with transparent adhesive 170, leaving only the air gap between the second plane area and the inner surface of the fourth lens 144. At this time, the multilayer lens has the highest strength and is not easily damaged.

[0146] For example, such as Figure 17 As shown, the fourth lens 144 and the fifth lens 145 can be clamped and fixed by the clamping member 160. The aforementioned clamping member 160 can be the eyeglass frame 111 itself, or it can be an additional clamping structure. With the aforementioned configuration, the lenses (e.g., the fifth lens 145) can be easily replaced as needed to achieve different effects (e.g., color correction, refractive correction, polarization, UV protection, photochromic lenses, etc.), increasing the wearer's autonomy and choice.

[0147] It is worth noting that multi-layered lenses can be encapsulated using one or more of the aforementioned methods. For example, the peripheral sides of the fourth lens 144 and the fifth lens 145 can be bonded together using adhesive 170, and the fourth lens 144 and the fifth lens 145 can be clamped and fixed by the clamping member 160, thereby improving the stability of the encapsulation of the fourth lens 144 and the fifth lens 145.
