A kind of anti-glare contact lens

Abstract

The invention discloses an anti-glare contact lens, which comprises a contact lens body, the contact lens body is made of silicon hydrogel, and includes an optical concave surface and an optical convex surface, wherein the optical convex surface has a central surface corresponding to the pupil and a central surface located around the central surface. surrounding surface; a first light reflective layer vacuum coated on the central surface; a second light reflective layer vacuum coated on the peripheral surface, the first light reflective layer being darker than the second light reflective layer; and vacuum coated on the first The light reflection layer and the multi-layer medium layer of the second light reflection layer. The present invention vacuum-coats the first light reflection layer and the second light reflection layer on the contact lens body, and matches with the iris of the pupil, so as to improve the anti-glare effect and avoid the troubles of single contact lenses and lack of anti-glare in the past.

Description

technical field [0001] The invention belongs to the technical field of contact lenses, in particular to an anti-glare contact lens. Background technique [0002] Lenses have been developed for a long time and are used in various fields such as optical instruments or glasses. Most of the lenses or glasses focus on shape design and optical lens functions. The prior art has so-called optical lenses of various materials, including plastics and glass. In order to meet the trend of lightness and thinness, spectacle lenses are generally made of plastic, which can be coated with films, such as anti-reflection film, anti-ultraviolet film, etc., but this kind of process requires a coating machine, such as a spin coater, to coat the film layer . And this kind of device is expensive, so it not only needs expensive instruments, but also adds many steps and man-hours. Because the film is coated on the surface of the lens, it is easy to scratch, and not the entire lens itself contains a...

Problems solved by technology

However, current contact lenses lack an anti-glare function for ordinary glasses, which cannot be compared with sun lenses.
