Abstract
PURPOSE:To produce a contact lens having high dimensional precision of shape with high mold releasability from a monomer having an optional compsn. by treating the surface of a casting mold consisting of an ethylene/vinyl alcohol copolymer to have water repellency then carrying out polymn. of the monomer after pouring the monomer in the casting mold. CONSTITUTION:An ethylene/vinyl alcohol copolymer is selected for a material of a casting mold, and the surface of the casting mold is treated so as to have water repellency. Then, a monomer is poured into the mold and polymerized in the mold. By this method, a soft contact lens having high dimensional precision of shape is produced with high mold releasability. Also, a hard contact lens requiring severer stand of dimensional precision of shape is produced with satisfactory mold releasability.
