- Various contact lenses have been commercially manufactured for many years. Early contact lenses were made of hard materials and these lenses are still used in some applications today but are not suitable for all patients because of their poor fit. Since then, soft contact lenses based on hydrogels have been developed and are very popular today. These lenses can be manufactured by molding the lens in a mold. For example, it may include a first mold part having a convex surface corresponding to the back curved surface of the ophthalmic lens, and a second mold part having a concave surface corresponding to the front curved surface of the ophthalmic lens. To produce a lens using such a mold part, an uncured hydrogel lens composition is placed between the concave and convex surfaces of the mold part and then cured. After curing, the mold parts are separated according to typical practice, and the lens remains attached to one mold part. The release process removes the lens from the remaining mold parts.
