Contact lens material with stain resistance |
| abstract |
(57) [Summary] [Purpose] To improve the stain resistance of contact lenses and improve the balance of physical properties. [Structure] A copolymer comprising a bifunctional organosiloxane macromer and / or a copolymerizable monomer having a specific structure and molecular weight. [Effect] This contact lens material has a stain resistance that is equal to or higher than that of the PMMA hard lens, and has an excellent balance of physical properties such as oxygen permeability. |
