发明名称 Method of manufacturing polarized spectacle lens
摘要 A film of a plastic material fusible with a lens-forming material and having a high light transmissivity is bonded and laminated, with an adhesive, to a polarizing sheet having a polarization coefficient of 99.0% or higher and a light transmissivity of 40% or higher. The resultant laminate is hot-pressed into a shape similar to an aimed lens. The hot-pressed laminate is placed in a lens forming mold cavity, and a lens-forming resin which has been colored or of which light transmissivity has been adjusted to a desired transmissivity is injected into the cavity to thereby form a polarized lens.
