MOLD CORE FOR PRODUCING CONTACT LENS HAVING TEAR DROP CIRCULATION PATHWAY IN ORDER TO ENHANCE OSMOSIS AND PROVIDES OXYGEN

摘要

A mold core for producing contact lens which has a tear drop circulation pathway is provided to supply and discharge moist to cornea and increase osmosis. A mold core for producing contact lens having tear drop circulation pathway to enhance osmosis function is formed by molding contact lens; forming concave surface of a first molding punch (24) through molding surface (22); forming a second molding punch having selectively protruded cornea contact protrusion; and molding a third molding punch.
