Abstract

1,129,688. Lenses. BAUSCH & LOMB Inc. Sept.26, 1966 [Oct.29, 1965], No.42936/66. Heading G2J. [Also in Division C3] A lens is obtained by polymerization in a suitably shaped mold of a mixture comprising (1) 75 to 90% of diethylene glycol bis (allyl carbonate), (2) 5 to 15% of an allyl -striazine, and (3) 5 to 20% of either a monoethylenically unsaturated manomer or an unsaturated polyester. The lens may be curved after removal from the mold. A diagram of a conventional mold used to produce the exemplified lenses is supplied.
