Abstract

The moulding of hydrophilic hydrogel contact lenses from a reactive monomer mixt comprises interposing cooperating concave and convex mould faces about a cavity to form contact lens blanks. At least one of the mould faces is treated with a transient wetting agent to facilitate wetting of the face with the monomer mixt and to provide lens blanks with reduced lens hole and puddle defects. Also claimed is the moulding of contact lens blanks including filling a concave lens mould with a reactive monomer mixt, and juxtaposing with it in mating moulding relation a convex lens mould. At least one of the optical surfaces of the moulds is pretreated with water vapour to condense an even coating of moisture on it to enhance wettability of the optical surface to the reactive monomer mixt.
