摘要
There is provided a mold comprising a male and a female mold member fabricated from thermoplastic polymeric materials which, in very thin sections are flexible under polymerization conditions, but, under said conditions are sufficiently inflexible in thick sections to retain their shape and surface characteristics. Said mold is provided, on either the male or the female member with a thin rim which, during the polymerization process, flexes and permits the old members to approach each other and compensate for the shrinkage that occurs during polymerization. Said thin rim further forms the edge of the finished lens.
