摘要: A plastics material mold for casting a contact lens from curable material. Disposable male and female members (20,22;50,51) define cavity each having curved surface (21,23;52,54) molding respective optical of the lens, member shoulder (26,53) which is slidable fit with generally cylindrical, e.g. frusto-conical, (25,55) on to permit relative movement during curing without substantially affecting quality molded surfaces. The sliding are relatively simple accuracy thus edge (29) eventual cast be formed reliably accurately.
