Description

Adjustable vision correction lens and glasses thereof Technical Field The application relates to the field of dimmable liquid crystals, in particular to a dimmable vision correction lens and glasses comprising the same. Background When the sun rays are strong and the condition that the sun rays are dazzled possibly exists, people can shield the dazzling rays by wearing sunglasses, so that the effect of normal object viewing can be achieved. The light transmittance of a general sunglasses is constant, and there is a problem in that the light transmittance cannot be adjusted according to different intensity of light. Furthermore, photochromic lenses appear in the market, and the traditional photochromic lenses realize chemical photochromic by adding silver halide, so that the lenses can automatically undergo chemical reaction to darken outdoors when meeting ultraviolet rays, and can automatically recover to a transparent state indoors or in places without ultraviolet rays, but the traditional photochromic lenses have the defects of low response speed and can not meet the requirement of rapid switching of the light transmittance of the dimming lenses. Currently, dimming liquid crystals are capable of realizing rapid response to the intensity change of light to adaptively change the light transmittance, and have been developed as a mainstream dimming tool. Attempts have been made to incorporate the dimming liquid crystal onto the vision correction lenses to facilitate the person in need of vision correction by (1) separately making the dimming liquid crystal into a dimming lens and then removably disposing it on the vision correction lens. The whole vision correction lens is complex and scattered in structure and inconvenient to use, and meanwhile, as the lens made of the dimming liquid crystal is positioned on the outer surface, the situation that the hand of a user contacts the lens and the lens is polluted or damaged often occurs. (2) The vision correcting lens is composed of two lenses to correct vision, and then the dimming liquid crystal is attached between the two lenses. In the above-mentioned mode, the optical center lines of two lenses need to be aligned in the production process of the vision correction lens, which is unfavorable for mass production, and meanwhile, the mode that the dimming liquid crystal is arranged between the two lenses can obviously increase the thickness of the whole vision correction lens, so that the whole vision correction lens is not attractive and inconvenient to use. Disclosure of Invention As described in the background section above, in view of one or more of the above problems, it is an object of the present application to provide a dimmable vision correction lens that has an attractive appearance, is comfortable to wear, and is suitable for mass production and manufacture. In order to achieve the above purpose, the present application is realized by the following technical scheme: The application provides a dimmable vision correction lens, which comprises a transparent protective layer, a flexible liquid crystal dimming layer and a vision correction lens which are laminated and laminated in sequence, wherein the joint surface of the flexible liquid crystal dimming layer and the vision correction lens is a convex surface of the vision correction lens; The curvature radius of the concave surface formed by the lamination of the transparent protective layer and the flexible liquid crystal dimming layer is R1, the curvature radius of the convex surface of the vision correction lens is R2, and the relationship between R1 and R2 is R2-50mm and R1 is less than or equal to R2 plus 50mm. In the adjustable vision correction lens, the transparent protective layer firstly plays roles of protecting the flexible liquid crystal dimming layer and preventing the flexible liquid crystal dimming layer from being polluted or scratched. The transparent protective layer is attached to the opposite side of the flexible liquid crystal dimming layer, which is far away from the vision correction lens, after the flexible liquid crystal dimming layer is attached to the convex surface of the vision correction lens, the curvature radius R1 of the concave surface of the transparent protective layer and the curvature radius R2 of the convex surface of the vision correction lens are guaranteed to meet the mathematical relation, and the arrangement is that the transparent protective layer and the flexible liquid crystal dimming layer almost have no influence on the vision correction effect of the vision correction lens, and further the transparent protective layer and the optical center line of the vision correction lens do not need to be aligned specially, so that the transparent protective layer and the vision correction lens are suitable for large-scale industrial production. Further, the thickness of the transparent protective layer is H, and the range of H is more than or equal to 0.1mm and less th
