IPC: G02F1/17
Filed: 1991-06-07
Abstract: PURPOSE:To obtain the contact lens having a light control function capable of effectively protecting the eyes against excessive light by mixing a specific light control dye with a specific plastic material monomer, polymerizing the mixture to a polymer and grinding and polishing the polymer. CONSTITUTION:The spironaphthoxazine light control dye expressed by formula I is dissolved at 0.001 to 5.0wt.% into the monomer mixture composed of 50 to 80 pts.wt. methyl methacrylate, 10 to 30 pts.wt. acryl ester 9 (or methacryl ester) expressed by formula II, 10 to 30 pts.wt. diacryl ester (or dimethacryl ester) expressed by formula III, and 3 to 20 pts.wt. alpha methyl styrene. After this soln. is polymerized, the polymer is ground and polished, by which the contact lens is obtd. This contact lens develops a color swiftly to incident light to control the transmittance. The lens fades swiftly to restore the original state on weakening of the incident light, thereby protecting the eyes against the excessive light.
