Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor fall within the scope of protection of the present application.

[0042] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed or can optionally include other steps or units inherent to the process, method, product or device.

[0043] The technical schemes in the embodiments of the present application will be described below in combination with the drawings.

[0044] It should be noted that, for the sake of illustration, in the embodiments of the present application, the same reference signs represent the same parts, and for the sake of brevity, detailed description of the same parts is omitted in different embodiments.

[0045] Astigmatism is a kind of abnormal refraction of the eye, which is related to the curvature of the cornea. After parallel light enters the eye, due to the unequal refractive power of the eyeball on different meridians, it cannot be collected at a point (focal point), and a clear image cannot be formed. This condition is called astigmatism. Astigmatism eyes cannot form a clear image by adjusting or moving the target between the eyes. Only by wearing appropriate cylindrical lenses can a clear image be formed on the retina. According to the manifestation, astigmatism can be divided into regular astigmatism and irregular astigmatism. Usually only regular astigmatism can be corrected by lenses, and irregular astigmatism can only be corrected by surgery. Among them, regular astigmatism is divided into simple myopic / hyperopic astigmatism and compound myopic / hyperopic astigmatism. Among them, simple myopic / hyperopic astigmatism can be directly corrected by cylindrical lenses, and according to the different needs of correcting simple myopic astigmatism and simple hyperopic astigmatism, it corresponds to negative cylindrical lenses and positive cylindrical lenses respectively. Compound myopic / hyperopic astigmatism needs to be corrected by cylindrical lenses and concave / convex lenses. Simple myopic astigmatism refers to one main meridian falling on the retina, and the other meridian focusing infinitely in front of the retina. Simple hyperopic astigmatism refers to one main meridian falling on the retina, and the other meridian focusing infinitely behind the retina. Compound myopic astigmatism refers to two perpendicular meridians focusing in front of the retina, but the focusing positions are different. Compound hyperopic astigmatism refers to two perpendicular meridians focusing behind the retina, but the focusing positions are different.

[0046] The correction degree of the current myopic astigmatism lens or hyperopic astigmatism lens is usually fixed, so a pair of lenses can only be used for one user and cannot be used for multiple users. When multiple users need to be used, multiple lenses need to be prepared, which greatly reduces the user experience.

[0047] See Figures 1 to 3 The embodiment of the present application provides a kind of astigmatism lens 100, it includes light transmission layer 10, elastic layer 30, first fluid 50 and adjusting mechanism 70. Elastic layer 30 is arranged on one side of the light transmission layer 10, and with the light transmission layer 10 enclosed into accommodating cavity 101;The first fluid 50 is sealed in the accommodating cavity 101;The adjusting mechanism 70 includes adjusting piece 71, the adjusting piece 71 is arranged on the surface of the elastic layer 30 away from the light transmission layer 10, the adjusting piece 71 includes multiple adjusting subpieces 711, the multiple adjusting subpieces 711 are sequentially arranged, so that the adjusting piece 71 is annular structure, the height of the multiple adjusting subpieces 711 can be adjusted;When the height of the multiple adjusting subpieces 711 changes according to preset rule, the multiple adjusting subpieces 711 extrude the elastic layer 30, so that the elastic layer 30 is deformed, to adjust the astigmatism degree of the astigmatism lens 100.

[0048] The astigmatic lens 100 of the embodiment of the present application can be applied to myopia glasses, hyperopia glasses, astigmatism glasses, augmented reality glasses and other wearable devices for correcting refractive errors.

[0049] Optionally, as shown in the initial state, the accommodation cavity 101 is filled with the first fluid 50, and the elastic layer 30 is in a flat state (i.e., the integrated lens does not have astigmatism). Figure 2

[0050] The astigmatic lens 100 of the embodiment of the present application adjusts the heights of the plurality of adjustment sub-components 711 so that the heights of the plurality of adjustment sub-components 711 change according to a preset rule, so that each adjustment sub-component 711 exerts different degrees of extrusion on the elastic layer 30, different positions of the elastic layer 30 move relative to the light-transmitting layer 10 by different degrees, and different degrees of extrusion are exerted on the first fluid 50. Under the joint action of the adjustment component 71 and the first fluid 50, the elastic layer 30 deforms. By controlling the change rule of the heights of the plurality of adjustment sub-components 711, the surface shape and curvature of the surface of the elastic layer 30 away from the light-transmitting layer 10 can be adjusted, so that the astigmatism can be continuously adjusted. Thus, a pair of glasses can be suitable for different users, and when applied to wearable devices such as augmented reality glasses (AR glasses), there is no need to customize different refractive correction lenses for different users, the range of suitable users is wider, and the user experience can be better improved.

[0051] Optionally, the astigmatic lens 100 is a cylindrical lens, the astigmatic lens 100 has an axis position, the cylindrical surface of the surface of the elastic layer 30 away from the light-transmitting layer 10, and the heights of the plurality of adjustment sub-components 711 change according to a preset rule to adjust the direction of the axis position of the astigmatic lens 100. In other words, by adjusting the height change trend of the plurality of adjustment sub-components 711, the direction of deformation of the elastic layer 30 is adjusted, so that the direction of the axis position of the astigmatic lens 100 is adjusted. Different astigmatic users have different directions of astigmatism (i.e., different directions of axis position), so even if the astigmatism of the lens is the same, the lens cannot be suitable for users with different axis positions of astigmatism. The astigmatic axis position of the astigmatic lens 100 of the present application can be adjusted as needed, so that it is suitable for users with different axis positions and different astigmatism, and the range of application is wider. The term "axis position" represents the direction of astigmatism. Astigmatism glasses need to be accurately and stably placed on the axis position to be corrected to ensure clear vision, so the more comprehensive the "axis position" provided by the astigmatism glasses is, the better the effect of correcting astigmatism will be.

[0052] ​Optionally, the adjustable myopic astigmatism power De1 of the astigmatic lens 100 ranges from 0° to 700°. Specifically, De1 can be, but is not limited to, 0°, 25°, 50°, 75°, 100°, 125°, 150°, 175°, 200°, 225°, 250°, 275°, 300°, 325°, 350°, 375°, 400°, 425°, 450°, 475°, 500°, 525°, 550°, 575°, 600°, 625°, 650°, 675°, 700°, etc. The higher the adjustable myopic astigmatism power of the astigmatic lens 100, the greater the curvature of the surface of the elastic layer 30 away from the light-transmitting layer 10.

[0053] Optionally, the adjustable hyperopic astigmatism power De2 of the astigmatic lens 100 ranges from 0° to 700°. Specifically, De2 can be, but is not limited to, 0°, 25°, 50°, 75°, 100°, 125°, 150°, 175°, 200°, 225°, 250°, 275°, 300°, 325°, 350°, 375°, 400°, 425°, 450°, 475°, 500°, 525°, 550°, 575°, 600°, 625°, 650°, 675°, 700°, etc. The higher the adjustable hyperopic astigmatism power of the astigmatic lens 100, the greater the curvature of the surface of the elastic layer 30 away from the light-transmitting layer 10.

[0054] In some embodiments, the refractive index n1 of the light-transmitting layer 10, the refractive index n2 of the elastic layer 30, and the refractive index n3 of the first fluid 50 satisfy the following relationships:

[0055] 0.95≤n1 / n2≤1.05;

[0056] 0.95≤n1 / n3≤1.05;

[0057] 0.95≤n2 / n3≤1.05.

[0058] Specifically, n1 / n2 can be, but is not limited to, 0.95, 0.96, 0.97, 0.98, 0.99, 1.01, 1.02, 1.03, 1.04, 1.05, etc. n1 / n3 can be, but is not limited to, 0.95, 0.96, 0.97, 0.98, 0.99, 1.01, 1.02, 1.03, 1.04, 1.05, etc. n2 / n3 can be, but is not limited to, 0.95, 0.96, 0.97, 0.98, 0.99, 1.01, 1.02, 1.03, 1.04, 1.05, etc.

[0059] The closer the refractive index n1 of the light-transmitting layer 10, the refractive index n2 of the elastic layer 30, and the refractive index n3 of the first fluid 50, the less likely the refraction occurs when the light passes through the interface between the light-transmitting layer 10 and the first fluid 50, and the interface between the first fluid 50 and the elastic layer 30. Therefore, the closer the refractive index n1 of the light-transmitting layer 10, the refractive index n2 of the elastic layer 30, and the refractive index n3 of the first fluid 50, the better.

[0060] In an embodiment, the refractive index n1 of the light-transmitting layer 10, the refractive index n2 of the elastic layer 30, and the refractive index n3 of the first fluid 50 are equal.

[0061] Optionally, the outer periphery of the elastic layer 30 is connected with the light-transmitting layer 10 to form a closed accommodation cavity 101, and the accommodation cavity 101 is filled with the first fluid 50.

[0062] The elastic modulus E1 of the light-transmitting layer 10 is in the range of E1≥50Gpa. Specifically, the elastic modulus E1 of the light-transmitting layer 10 can be, but is not limited to, 50Gpa, 53Gpa, 55Gpa, 60Gpa, 70Gpa, 80Gpa, 90Gpa, 100Gpa, etc. The elastic modulus E1 of the light-transmitting layer 10 should not be too low. When the elastic modulus of the light-transmitting layer 10 is too low, it is difficult to ensure that the light-transmitting layer 10 always remains flat and does not deform during the adjustment of the astigmatism power of the astigmatism lens 100. The greater the elastic modulus E1 of the light-transmitting layer 10, the thinner the light-transmitting layer 10 can be made, which is more conducive to the lightness and thinness of the astigmatism lens 100. However, as the elastic modulus of the light-transmitting layer 10 increases, the requirements for the material of the light-transmitting layer 10 become higher, which increases the cost of the light-transmitting layer 10.

[0063] Optionally, the light-transmitting rate of the light-transmitting layer 10 is greater than or equal to 85%. Further, the light-transmitting rate of the light-transmitting layer 10 is greater than or equal to 90%. Further, the light-transmitting rate of the light-transmitting layer 10 is greater than or equal to 95%. Specifically, the light-transmitting rate of the light-transmitting layer 10 can be, but is not limited to, 85%, 88%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, etc. The higher the light-transmitting rate of the light-transmitting layer 10, the better the visual effect of the integrated lens 100.

[0064] Optionally, the material of the light-transmitting layer 10 can be, but is not limited to, at least one of polymethyl methacrylate (PMMA), polycarbonate (PC), glass, sapphire, etc. These materials are generally light-transmitting, can make the astigmatism lens 100 have better color uniformity and better appearance, and are easy to obtain a light-transmitting layer 10 with an elastic modulus greater than 50Gpa.

[0065] Optionally, the thickness of the light-transmitting layer 10 ranges from 1 mm to 4 mm. Specifically, the thickness of the light-transmitting layer 10 can be, but is not limited to, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm. If the thickness of the light-transmitting layer 10 is too thin, the light-transmitting layer 10 is prone to deformation or damage during the adjustment of the astigmatism of the astigmatism lens 100. If the thickness of the light-transmitting layer 10 is too thick, the weight and thickness of the astigmatism lens 100 are increased, which is not conducive to the lightness and thinness of the astigmatism lens 100. In the embodiments of the present application, when a numerical range a to b is mentioned, unless otherwise specified, it means that the end point value a is included and the end point value b is included. For example, the thickness of the light-transmitting layer 10 ranges from 1 mm to 4 mm, which means that the thickness of the light-transmitting layer 10 can be any value between 1 mm and 4 mm, including the end point 1 mm and the end point 4 mm.

[0066] In some embodiments, the elastic layer 30 has a first surface 32 facing away from the light-transmitting layer 10, and the adjustable radius of curvature R of the first surface 32 in the direction perpendicular to the axial position ranges from R≥0.065 m. Further, the adjustable radius of curvature R1 of the second surface 32 in the direction perpendicular to the axial position ranges from 0.065 m≤R1≤1.84 m. Specifically, the adjustable radius of curvature R1 of the second surface 32 in the direction perpendicular to the axial position can be, but is not limited to, 0.065 m, 0.08 m, 0.1 m, 0.3 m, 0.5 m, 0.8 m, 1.0 m, 1.2 m, 1.4 m, 1.6, 1.84 m, 2.0 m, 3.0 m, 5 m, 8 m, etc. The smaller the radius of curvature, the greater the curvature, and the higher the myopic astigmatism or hyperopic astigmatism degree that the astigmatism lens 100 can adjust.

[0067] In some embodiments, the elastic modulus E2 of the elastic layer 30 ranges from 10 Mpa≤E2≤100 Mpa. Specifically, the elastic modulus E2 of the elastic layer 30 can be, but is not limited to, 10 Mpa, 20 Mpa, 30 Mpa, 40 Mpa, 50 Mpa, 60 Mpa, 70 Mpa, 80 Mpa, 90 Mpa, 100 Mpa, etc. The elastic modulus of the elastic layer 30 should not be too large or too small. If the elastic modulus of the elastic layer 30 is too large, it increases the difficulty of adjusting the astigmatism degree of the astigmatism lens 100. If the elastic modulus of the elastic layer 30 is too small, the elastic layer 30 is obviously affected by external forces such as gravity, for example, due to inertia factors (such as inertia generated by the movement of the elastic layer 30 when adjusting the height of the adjusting sub-component 711), which causes the elastic layer 30 to deform and makes it difficult to maintain the shape of the elastic layer 30, thereby affecting the adjustment of the astigmatism degree of the astigmatism lens 100.

[0068] Optionally, the elastic layer 30 is light-transmissive, and the light transmittance of the elastic layer 30 is greater than or equal to 85%. Further, the light transmittance of the elastic layer 30 is greater than or equal to 90%. Further, the light transmittance of the elastic layer 30 is greater than or equal to 95%. Specifically, the light transmittance of the elastic layer 30 can be, but is not limited to, 85%, 88%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, etc. The higher the light transmittance of the elastic layer 30, the better the visual effect of the astigmatic lens 100.

[0069] Optionally, the material of the elastic layer 30 can be, but is not limited to, at least one of polydimethylsiloxane (PDMA), polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), etc. These materials are generally light-transmissive, which can make the astigmatic lens 100 have better overall color uniformity and better appearance.

[0070] Optionally, the thickness of the elastic layer 30 ranges from 50 μm to 300 μm in the direction of the stacking of the elastic layer 30 and the light-transmissive layer 10. Further, the thickness of the elastic layer 30 ranges from 100 μm to 200 μm. Specifically, the thickness of the elastic layer 30 can be, but is not limited to, 50 μm, 60 μm, 70 μm, 80 μm, 100 μm, 120 μm, 150 μm, 180 μm, 200 μm, 220 μm, 250 μm, 280 μm, 300 μm, etc. If the elastic layer 30 is too thin, the middle position of the elastic layer 30 is prone to sagging when the astigmatic power is adjusted, and it is difficult to maintain the ideal cylindrical surface. If the elastic layer 30 is too thick, it is difficult to control the deformation of the elastic layer 30 through the adjusting sub-piece 711, which increases the difficulty of astigmatic power adjustment.

[0071] Optionally, the light-transmissive layer 10 and the elastic layer 30 can be bonded together by welding (e.g., after the light-transmissive layer 10 and the elastic layer 30 are bonded, high temperature and high pressure are applied to melt the materials of the light-transmissive layer 10 and the elastic layer 30, and then the light-transmissive layer 10 and the elastic layer 30 are combined together), hot melt adhesive, light-cured glue (UV glue), optical adhesive (OCA glue), etc. When the materials of the light-transmissive layer 10 and the elastic layer 30 are PMMA or PC, the light-transmissive layer 10 and the elastic layer 30 can be bonded by welding, and when the materials of the light-transmissive layer 10 and the elastic layer 30 are other materials, the light-transmissive layer 10 and the elastic layer 30 can be bonded together by hot melt adhesive, light-cured glue (UV glue), optical adhesive (OCA glue), etc.

[0072] Optionally, the first fluid 50 can be, but is not limited to, at least one of dimethyl silicone oil, polyethylene glycol (such as PEG200), and the like. Optionally, the refractive index of the first fluid 50 is greater than 1.4, and specifically, the refractive index of the first fluid 50 can be, but is not limited to, 1.4, 1.43, 1.45, 1.48, 1.50, 1.53, 1.45, 1.48, 1.60, 1.62, 1.65, 1.67, 1.7, and the like.

[0073] Please refer to Figure 4 and Figure 5 In some embodiments, the first surface 32 is a convex cylindrical surface (as shown in Figure 4 ) or a concave cylindrical surface (as shown in Figure 5 ). The adjusting member 71 has a second surface 72 facing the elastic layer 30. When the heights of the plurality of adjusting sub-members 711 change according to a predetermined rule so that the second surface 72 is a concave cylindrical surface, the plurality of adjusting sub-members 711 press and deform the elastic layer 30 so that the first surface 32 is a convex cylindrical surface, and the astigmatic lens 100 is used to correct simple hyperopic astigmatism. When the heights of the plurality of adjusting sub-members 711 change according to a predetermined rule so that the second surface 72 is a convex cylindrical surface, the plurality of adjusting sub-members 711 press and deform the elastic layer 30 so that the first surface 32 is a concave cylindrical surface, and the astigmatic lens 100 is used to correct simple myopic astigmatism. By independently adjusting the height of each adjusting sub-member 711, the surface of the adjusting member 71 facing the elastic layer 30 is a convex cylindrical surface or a concave cylindrical surface, and the curvature of the convex cylindrical surface or the concave cylindrical surface is adjusted, so that the elastic layer 30 is deformed to press the first fluid 50, and the surface of the elastic layer 30 away from the light-transmitting layer 10 is a complementary concave cylindrical surface or convex cylindrical surface, thereby adjusting the astigmatism and the axis. The adjusting method is simple and easy to implement.

[0074] Optionally, the overall structure of the adjusting member 71 is a ring structure, that is, the plurality of adjusting sub-members 711 are arranged in sequence to form a ring structure. The second surface 72 is a concave cylindrical surface. Understandably, the surface of the ring structure of the adjusting member 71 facing the elastic layer 30 forms a concave cylindrical surface. The heights of the adjusting sub-members 711 at both ends of the concave are higher, which will press the elastic layer 30 more to move towards the direction close to the light-transmitting layer 10, while the height of the adjusting sub-members 711 in the middle of the concave is lower, and the elastic layer 30 at the position in the middle of the concave moves away from the light-transmitting layer 10, so that the first surface 32 is a convex cylindrical surface.

[0075] Similarly, the second surface 72 is a convex cylindrical surface, and it can be understood that the surface of the annular structure of the adjusting member 71 facing the elastic layer 30 forms a cylindrical surface protruding towards the elastic layer 30. The adjusting sub-member 711 in the middle of the protrusion has a higher height, which can press the elastic layer 30 more to move towards the transparent layer 10, while the height of the two ends of the protrusion is lower, and the elastic layer 30 at the position of the two ends of the protrusion is moved away from the transparent layer 10, so that the first surface 32 is a concave cylindrical surface.

[0076] It can be understood that during the adjustment of the astigmatism power of the astigmatism lens 100, the adjusting member 71 always bears against the elastic layer 30, in other words, the adjusting member 71 always adheres to the elastic layer 30. Therefore, the curvatures of the first surface 32 and the second surface 72 are equal.

[0077] Please refer to Figures 6 to 8 In some embodiments, when the astigmatism lens 100 is used to correct astigmatism, the plurality of adjusting sub-members 711 includes oppositely arranged first and second adjusting sub-members 711a and 711b, and oppositely arranged third and fourth adjusting sub-members 711c and 711d, and the line connecting the first and second adjusting sub-members 711a and 711b intersects the line connecting the third and fourth adjusting sub-members 711c and 711d. The change trend of the height of the plurality of adjusting sub-members 711 is the same in the direction from the third adjusting sub-member 711c to the first adjusting sub-member 711a, in the direction from the third adjusting sub-member 711c to the second adjusting sub-member 711b, in the direction from the fourth adjusting sub-member 711d to the first adjusting sub-member 711a, and in the direction from the fourth adjusting sub-member 711d to the second adjusting sub-member 711b, and the change trend is gradually increasing or gradually decreasing.

[0078] In other words, as shown in Figure 7 and Figure 8 When the change trend is gradually decreasing, the height of the plurality of adjusting sub-members 711 gradually decreases in the direction from the third adjusting sub-member 711c to the first adjusting sub-member 711a, in the direction from the third adjusting sub-member 711c to the second adjusting sub-member 711b, in the direction from the fourth adjusting sub-member 711d to the first adjusting sub-member 711a, and in the direction from the fourth adjusting sub-member 711d to the second adjusting sub-member 711b, at this time, the second surface 72 is a convex cylindrical surface, the first surface 32 is a concave cylindrical surface, and the astigmatism lens 100 is used to adjust myopic astigmatism. As shown in Figure 9As shown, when the change trend is gradually increasing, the height of the plurality of adjustment sub-pieces 711 gradually increases in the direction from the third adjustment sub-piece 711c to the first adjustment sub-piece 711a, in the direction from the third adjustment sub-piece 711c to the second adjustment sub-piece 711b, in the direction from the fourth adjustment sub-piece 711d to the first adjustment sub-piece 711a, and in the direction from the fourth adjustment sub-piece 711d to the second adjustment sub-piece 711b. At this time, the second surface 72 is a concave cylindrical surface, and the first surface 32 is a convex cylindrical surface. The astigmatic lens 100 is used to adjust far vision astigmatism. By adjusting the height of the plurality of adjustment sub-pieces 711, not only can the correction of any astigmatism degree (myopic astigmatism and hyperopic astigmatism) be achieved, but also the direction of the axis can be adjusted to achieve the correction of astigmatism of any axis.

[0079] In an embodiment, the line connecting the first adjustment sub-piece 711a and the second adjustment sub-piece 711b is perpendicular to the line connecting the third adjustment sub-piece 711c and the fourth adjustment sub-piece 711d.

[0080] It can be understood that the plurality of adjustment sub-pieces 711 are arranged in sequence to form a ring structure composed of a plurality of cavities containing the second fluid, forming a hollow ring cavity structure.

[0081] Optionally, the plurality of adjustment sub-pieces 711 are closely arranged on the surface of the elastic layer 30 away from the light-transmitting layer 10 and enclosed to form a ring structure.

[0082] Optionally, the plurality of adjustment sub-pieces 711 are spaced apart from the outer periphery of the elastic layer 30 by a certain distance, so that when the astigmatic lens 100 is assembled to the carrier of the wearable device, the part of the elastic layer 30 from the adjustment sub-piece 711 to the outer periphery can closely fit the inner wall of the carrier. Optionally, the spacing distance between the adjustment sub-piece 711 and the outer periphery of the elastic layer 30 ranges from 1 mm to 5 mm; specifically, it can be, but is not limited to, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc.

[0083] Optionally, each adjustment sub-piece 711 can be adhered to the elastic layer 30 by hot melt adhesive, light-cured glue (UV glue), optical glue (OCA glue), etc.

[0084] Optionally, the number of adjustment sub-pieces 711 is greater than or equal to 24. Further, the number of adjustment sub-pieces 711 ranges from 24 to 128; specifically, it can be, but is not limited to, 24, 28, 32, 36, 40, 44, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, and the like. The more the number of adjustment sub-pieces 711, the higher the adjustment accuracy of the astigmatism power of the astigmatism lens 100, but the more the number, the more complex the process.

[0085] Optionally, the material of the adjustment sub-piece 711 can include, but is not limited to, at least one of polydimethylsiloxane (PDMS), polycarbonate (PC), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), and the like.

[0086] Optionally, the material of the adjustment sub-piece 711 can include, but is not limited to, at least one of polydimethylsiloxane (PDMS), polycarbonate (PC), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), and the like.

[0087] Optionally, the adjustment sub-piece 711 can be an elastic balloon, and the wall thickness of the elastic balloon ranges from 0.01 mm to 0.3 mm; specifically, it can be, but is not limited to, 0.01 mm, 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, and the like. If the wall thickness of the elastic balloon is too thin, it will affect the service life of the astigmatism lens 100 and is not conducive to the stability of the astigmatism power of the astigmatism lens 100. If the wall thickness of the elastic balloon is too thick, it will increase the thickness and weight of the astigmatism lens 100, which is not conducive to the lightness and thinness of the astigmatism lens 100.

[0088] In some embodiments, the height h of each of the adjusting sub-members 711 can be adjusted in the range of 0.2mm≤h≤3mm along the stacking direction of the light-transmitting layer 10, the elastic layer 30 and the adjusting member 71. Specifically, the height h of each of the adjusting sub-members 711 can be, but is not limited to, 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2.0mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3.0mm. The smaller the height of the adjusting sub-members 711 can be adjusted, the smaller the astigmatism degree of the astigmatism lens 100 can be corrected, and the higher the height of the adjusting sub-members 711 can be adjusted, the higher the astigmatism degree of the astigmatism lens 100 can be adjusted. However, when the height of the adjusting sub-members 711 can be adjusted exceeds a certain value, the thickness of the astigmatism lens 100 will be increased, which is not conducive to the miniaturization of the astigmatism lens 100.

[0089] Please refer to Figure 10 and Figure 11 In some embodiments, the adjusting mechanism 70 further comprises an actuator 73 configured to adjust the volume of each of the adjusting sub-members 711 according to a preset rule, so as to adjust the height of the adjusting sub-members 711 along the stacking direction of the light-transmitting layer 10, the elastic layer 30 and the adjusting member 71. The volume of the adjusting sub-members 711 is controlled by the actuator 73, so as to control the height of the adjusting sub-members 711. The adjusting method is simple and easy to implement.

[0090] In some embodiments, the adjusting sub-members 711 are elastic balloons (e.g. elastic air bags), and the adjusting mechanism 70 further comprises a second fluid (not shown in the figure) and a plurality of valves 75. The second fluid is located in the adjusting sub-members 711. Each of the valves 75 is connected to one of the adjusting sub-members 711, and different valves 75 are connected to different adjusting sub-members 711. The actuator 73 is connected to the plurality of valves 75. When the actuator 73 and the plurality of valves 75 are both opened, the actuator 73 is configured to adjust the amount of the second fluid in the adjusting sub-members 711, so as to adjust the volume of the adjusting sub-members 711, thereby changing the height of the adjusting sub-members 711 according to a preset rule, and achieving the adjustment of the astigmatism degree of the astigmatism lens 100.

[0091] The term "connected" in the present application can mean that two components are directly connected, or that two components are connected through a pipe or a pipeline.

[0092] Optionally, when the astigmatism lens 100 is in an initial state, each of the elastic air bags is in a semi-inflated state. At this time, the size of each of the elastic air bags is the same, and therefore, the elastic layer 30 is also in a planar state, and the astigmatism lens 100 does not have an astigmatism degree.

[0093] When the actuator 73 injects the second fluid into the adjusting sub-member 711 (i.e. the elastic balloon), the amount of the second fluid in the adjusting sub-member 711 increases, the volume of the adjusting sub-member 711 expands, and the height increases. When the actuator 73 extracts the second fluid from the adjusting sub-member 711, the amount of the second fluid in the adjusting sub-member 711 decreases, the volume of the adjusting sub-member 711 shrinks, and the height decreases. By controlling the amount of the second fluid in the adjusting sub-member 711, the adjusting sub-member 711 expands or shrinks, i.e. the volume of the adjusting sub-member 711 changes, so as to control the height of the adjusting sub-member 711. The method is simple and easy to implement. In addition, each adjusting sub-member 711 is provided with a valve 75, and by controlling the opening degree of the valve 75, the height of each adjusting sub-member 711 can be independently controlled.

[0094] Please refer to Figure 6 and Figure 7 Specifically, when the astigmatic lens 100 is used to adjust the myopic astigmatism (for example, 90° axis astigmatism), the 8th adjusting sub-member 711, the 9th adjusting sub-member 711, the 24th adjusting sub-member 711 and the 25th adjusting sub-member 711 are all filled with the second fluid (for example, filled with gas), because the adjusting sub-members 711 expand, the elastic layer 30 is pressed to move towards the light-transmitting layer 10, the second fluid of the 1st adjusting sub-member 711, the 16th adjusting sub-member 711, the 17th adjusting sub-member 711 and the 32nd adjusting sub-member 711 are all released, the adjusting sub-members 711 shrink, and the elastic layer 30 moves away from the light-transmitting layer 10, the adjusting sub-members 711 in the middle part change uniformly, so that the surface of the adjusting member 71 facing the elastic layer 30 changes uniformly. At this time, the first surface 32 of the elastic layer 30 forms a smooth concave cylindrical surface, and the simple myopic astigmatism can be corrected. Conversely, if the astigmatic lens 100 is used to adjust the hyperopic astigmatism (for example, 90° axis astigmatism), the 1st adjusting sub-member 711, the 16th adjusting sub-member 711, the 17th adjusting sub-member 711 and the 32nd adjusting sub-member 711 are all filled with the second fluid (for example, filled with gas), because the adjusting sub-members 711 expand, the elastic layer 30 is pressed to move away from the light-transmitting layer 10, the second fluid of the 8th adjusting sub-member 711, the 9th adjusting sub-member 711, the 24th adjusting sub-member 711 and the 25th adjusting sub-member 711 are all released, the adjusting sub-members 711 shrink, and the elastic layer 30 moves towards the light-transmitting layer 10, the adjusting sub-members 711 in the middle part change uniformly, so that the surface of the adjusting member 71 facing the elastic layer 30 changes uniformly. At this time, the first surface 32 of the elastic layer 30 forms a smooth convex cylindrical surface, and the simple hyperopic astigmatism can be corrected. Figure 6 and Figure 9As shown, when the astigmatism lens 100 is used to adjust the hyperopic astigmatism (for example, 90° axis astigmatism), the 1st adjusting sub-piece 711, the 16th adjusting sub-piece 711, the 17th adjusting sub-piece 711 and the 32nd adjusting sub-piece 711 are all filled with the second fluid (for example, filled with gas), due to the expansion of the adjusting sub-piece 711, the elastic layer 30 is pressed to be close to the light-transmitting layer 10, the second fluid of the 8th adjusting sub-piece 711, the 9th adjusting sub-piece 711, the 24th adjusting sub-piece 711 and the 25th adjusting sub-piece 711 is all released, the adjusting sub-piece 711 shrinks, drives the elastic layer 30 to move away from the light-transmitting layer 10, the adjusting sub-piece 711 in the middle part changes uniformly, the surface of the adjusting piece 71 facing the elastic layer 30 changes uniformly, at this time, the first surface 32 of the elastic layer 30 forms a smooth convex cylindrical surface, and the myopic astigmatism can be corrected. By changing the amount of the second fluid (for example, gas) in each adjusting sub-piece 711 (such as an elastic air bag), the shape of the first surface 32 of the elastic layer 30 can be adjusted arbitrarily, the astigmatism degree can be adjusted, and even the adjustment state of the pure myopic astigmatism to the adjustment state of the pure hyperopic astigmatism can be changed. In addition, since the astigmatism degree of each person also has the difference of the axis position, the change of the arbitrary astigmatism axis position can also be realized by using the technical solution.

[0095] Optionally, the second fluid can be gas or liquid. When the second fluid is gas, the actuator 73 is a micro gas pump. When the second fluid is liquid, the actuator 73 can be a micro liquid pump or a micro pump. The "micro gas pump" refers to a gas conveying device with small volume, whose working medium is gas, and which is mainly used for gas sampling, gas circulation, vacuum adsorption, vacuum pressure preservation, air extraction, air inflation, pressure increase and other purposes. The "micro liquid pump" is a piezoelectric pump which realizes the movement of the third fluid 36 by using the piezoelectric principle.

[0096] Optionally, the number of the actuator 73 can be one or more, and the number of the actuator 73 is less than or equal to the number of the adjusting sub-piece 711. When the number of the actuator 73 is one, the actuator 73 is connected to each valve 75 respectively. When the number of the actuator 73 is more than one, each actuator 73 is connected to multiple adjusting sub-pieces 711, different actuators 73 are connected to different adjusting sub-pieces 711, and multiple actuators 73 cooperate to adjust the height of the multiple adjusting sub-pieces 711. The fewer the number of the actuator 73 is, the more conducive to the light and thin of the astigmatism lens 100, but the lower the adjustment efficiency of the astigmatism lens 100 is when the astigmatism lens 100 adjusts the astigmatism. The more the number of the actuator 73 is, the higher the adjustment efficiency of the astigmatism lens 100 is when the astigmatism lens 100 adjusts the astigmatism, but it is not conducive to the light and thin of the astigmatism lens 100.

[0097] For example, when the number of actuators 73 is two and the number of adjustment sub-members 711 is 32, one of the actuators 73 is in communication with 16 of the adjustment sub-members 711, and the other of the actuators 73 is in communication with the remaining 16 of the adjustment sub-members 711. For another example, when the number of actuators 73 is four and the number of adjustment sub-members 711 is 32, each of the actuators 73 is in communication with 8 of the adjustment sub-members 711, and different actuators 73 are in communication with different adjustment sub-members 711.

[0098] Optionally, the valve 75 can be, but is not limited to, a micro electro-controlled valve 75, a micro electromagnetic valve 75, etc.

[0099] Referring to Figure 12 and Figure 13 , the present application also provides an integrated lens 100, which comprises the astigmatic lens 100 described in the above embodiments of the present application and an optical waveguide assembly 210, wherein the optical waveguide assembly 210 is arranged on one side of the astigmatic lens 100.

[0100] The integrated lens 100 of the present application integrates the functions of simple myopic astigmatism, simple hyperopic astigmatism and AR, and the astigmatism power and axis position are adjustable. The multiple functions are integrated into one lens, which not only can be applied to more users, but also is more miniaturized and lightweight.

[0101] As shown in Figure 12 , in some embodiments, the optical waveguide assembly 210 is arranged on the side of the light-transmitting layer 10 away from the adjustment member.

[0102] As shown in Figure 13 , in some other embodiments, the optical waveguide assembly 210 is arranged on the side of the adjustment member 71 away from the light-transmitting layer 10. Specifically, the optical waveguide assembly 210 is arranged on the surface of the adjustment member 71 away from the light-transmitting layer 10. The optical waveguide assembly 210 supports the adjustment member 71, and the surface of the optical waveguide assembly 210 facing the astigmatic lens 100 is a plane, so that the surface of the adjustment member 71 away from the elastic layer 30 always remains in a plane state.

[0103] Referring to Figure 14 and Figure 15 , in some embodiments, the optical waveguide assembly 210 comprises a first protective sheet 211, an optical waveguide sheet 213 and a second protective sheet 215 which are sequentially stacked and spaced apart. The first protective sheet 211 is arranged away from the astigmatic lens compared with the second protective sheet 215; and the first protective sheet 211 and the second protective sheet 215 are used for protecting the optical waveguide sheet 213.

[0104] Optionally, the light waveguide sheet 213 comprises a light transmission part 2131, a light in-coupling part 2133 and a light out-coupling part 2135. The light in-coupling part 2133 and the light out-coupling part 2135 are arranged on the surface of the light transmission part 2131 facing the first protective sheet 211. The light in-coupling part 2133 is configured to receive the optical signal entering the light waveguide sheet 213 and couple the optical signal into the light transmission part 2131. The light transmission part 2131 is configured to transmit the optical signal. The light out-coupling part 2135 is configured to receive the optical signal transmitted by the light transmission part 2131 and couple the optical signal out of the light waveguide sheet 213. The light out-coupling part 2135 can also be configured to expand the optical signal in one or two dimensions. The light waveguide sheet 213 is fragile and easily broken when falling or being hit. The first protective sheet 211 and the second protective sheet 215 arranged on the opposite surfaces of the light waveguide sheet 213 can effectively protect the light waveguide sheet 213 and prolong the service life of the light waveguide sheet 213.

[0105] Optionally, the light waveguide sheet 213 can be a geometric waveguide or a diffractive waveguide, but is not limited thereto. The diffractive waveguide can be a surface relief grating or a volumetric holographic grating.

[0106] Optionally, when the light waveguide sheet 213 is a diffractive waveguide sheet 213, the light in-coupling part 2133 is a in-coupling grating and the light out-coupling part 2135 is a out-coupling grating. In some embodiments, when the light waveguide sheet 213 is a diffractive waveguide sheet 213, the light waveguide sheet 213 further comprises a turning grating. The turning grating, the light in-coupling part 2133 and the light out-coupling part 2135 are arranged on the same surface of the light transmission part 2131. When the light waveguide sheet 213 is a geometric waveguide sheet 213, the light in-coupling part 2133 is a reflecting surface or a reflecting prism, and the light out-coupling part 2135 is a half-transmission half-reflection mirror array.

[0107] Optionally, the first protective sheet 211 and the second protective sheet 215 can be adhered to the opposite sides of the light waveguide sheet 213 by an adhesive frame (not shown) such as a UV adhesive, an optical adhesive (OCA), a heat-resistant adhesive, a hot-melt adhesive, a double-sided adhesive, a foam adhesive, etc. In addition, the adhesive frame can also be used to arrange the first protective sheet 211 and the second protective sheet 215 away from the light waveguide sheet 213 to form an air layer, so that the optical signal can better undergo total reflection when transmitting in the light waveguide sheet 213. It should be noted that the adhesive frame is arranged on the outer periphery of the first protective sheet 211 and the second protective sheet 215.

[0108] Optionally, the material of the first protective sheet 211 includes at least one of polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), reinforced glass, sapphire, and the like.

[0109] Optionally, the material of the second protective sheet 215 includes at least one of polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), reinforced glass, sapphire, and the like.

The first bearing portion 313 supports the adjustment piece 71 so that the surface of the adjustment piece 71 facing the first bearing portion 313 always maintains a planar state during the astigmatic adjustment process. It can be understood that the plurality of adjustment sub-pieces 711 are sequentially arranged around the inner wall of the support portion 311, and each adjustment sub-piece 711 is adhesively arranged with the inner wall of the support portion 311.

Understandably, the plurality of adjusting sub-members 711 are arranged in sequence around the inner wall of the support part 311, and each adjusting sub-member 711 is arranged in close contact with the inner wall of the support part 311.

[0122] Please refer to Figure 20 When the wearable device 300 comprises the integrated lens 200, and the adjusting member 71 is closer to the light waveguide assembly 210 than the transparent layer 10, the surface of each adjusting sub-member 711 facing the inner wall of the support part 311 can be adhesively arranged with the inner wall of the support part 311 by means of hot melt adhesive, light-cured adhesive (UV adhesive), optical adhesive (OCA adhesive), etc. The surfaces of the plurality of adjusting sub-members 711 facing the inner wall of the second protective sheet 215 abut against the second protective sheet 215, and the second protective sheet 215 supports the adjusting member 71, so that the surface of the adjusting member 71 facing the second protective sheet 215 always remains planar during the astigmatism adjustment process.
