Abstract

PURPOSE:To mold the plastic lens easily by a method wherein a sealing film is adhered around the periphery of two pieces of molds to form a cavity while liquid plastic material is poured into the cavity and is cured. CONSTITUTION:The cavity 18 is formed by adhering the sealing film 17 around the periphery of the side surfaces of the molds 9, 10 under a condition that the two pieces of the molds 9, 10 are held by mold holding equipments 11, 12. The plastic material containing liquid curable composition as the principal constituent thereof is poured into said cavity 18 and is cured to mold the plastic lens. The sealing film 17 such as a simple tape or the like is satisfactory in a sealing property, a heat resistance and a flexibility, further, it may be used in spite of the difference of the kind of the lens.
