Abstract
1339150 Spectacle lenses VERGO S A 9 Dec 1971 [14 Dec 1970] 57203/71 Heading G2J [Also in Division B5] Spectacle lenses etc. made from organic, polarizing material are formed by placing a previously curved, rigid polarizing screen coated with adhesive in a mould, filling the mould with a polymerizable liquid monomer, polymerizing the monomer, opening the mould and withdrawing the lens. The screen may be cut from a laminated sheet and curved by shaping under high frequency, ultrasonics or in vacuo and may be a film of polyvinyl alcohol coated on both sides with a protecting layer of cellulose ester. The adhesive may be of the cellulose, vinyl, epoxy or polyurethane type. The mould may comprise two matrices e.g. of polished steel or glass and an elastic packing held by a gripper e.g. of spring steel. The monomer may be a vinyl monomer e.g. a styrene, acrylic or allyl derivative, or a polycondensable prepolymer such as urea-formaldehyde or phenol formaldehyde and may contain pigment, polymerisation or polycondensation catalysts and/or ultraviolet or infrared absorbents.
