Plastic lens composition and method for the production thereof |
摘要 |
A method for making a plastic lens and a plastic lens made thereby. The method comprises disposing a liquid monomer or a monomer mixture and a photosensitive initiator into a mold cavity and directing ultraviolet light to act on the lens forming material in the cavity to produce a lens therefrom. The liquid monomer mixture may include one or more of diethylene glycol bis(allyl)-carbonate, bisphenol A diallyl carbonate, 1,6 hexanedioldimethacrylate, trimethylol propane triacrylate, tetraethylene glycol diacrylate, tripropylene glycol diacrylate, tetrahydrofurfurylmethacrylate, tetrahydrofurfuryl acrylate and styrene. The photosensitive initiator may be selected from the group of 2-hydroxy-2-methyl-1- phenyl-propan-1-one and 1-hydroxycyclohexyl phenyl ketone.
