CA 2007536

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