Plastic lens |
| abstract |
ABSTRACT OF THE DISCLOSURE A plastic lens of a stepped segment having an excellent surface hardness can be obtained at high molding efficiency from cast polymerization of a 95-50% by weight diethylene glycol bisallyl carbonate and 5-50% by weight of a monomer selected from methyl, ethyl, cyclohexyl, glycidyl acrylates and diacrylates, and 0.1 to 25% by weight of a second monomer selected from diacrylates and dimethacrylates of diethylene glycol, triethylene glycol and tetraethylene glycol. The % by weight are based on the weight of diethylene glycol bisallyl carbonate and the first monomer. |
