1, the materials of contact lenses are: silicone hydrogel water and polymers including methyl methacrylate, 2- hydroxyethyl methacrylate, glycerol methacrylate, etc.

2. Contact lenses, also known as contact lenses, are lenses worn on the cornea of the eye to correct vision or protect the eyes. The material is mainly composed of silicon hydrogel water and polymers including methyl methacrylate, 2- hydroxyethyl methacrylate and glycerol methacrylate. Generally speaking, the central thickness of low water-containing lenses is relatively higher, and the central thickness of water-containing lenses will be designed to be thicker.
