Problems solved by technology

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 applied on the surface of the lens, it is easy to scratch, and not the entire lens itself contains anti-ultraviolet material, which has limited effect

Abstract

A method of forming a contact lens includes a step of preparing a base material and halide material, followed by mixing the halide material into the base material when the molding process is performed to allow the halide material in the contact lens.

Description

technical field [0001] The invention relates to a contact lens, in particular to a filterable infrared 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 anti-ultraviolet...
