| abstract | [Constitution] Polycarbonate resin (A) 97 to 99.95% by weight and polystyrene resin (B) 0.05 to 3% by weight of polystyrene resin (B) having a weight average molecular weight of 1000 to 18000, 100 parts by weight of phosphorus antioxidant A polycarbonate resin composition (F) comprising 0.02 to 2 parts by weight of (C) and / or a phenolic antioxidant (D) and 0.15 to 0.9 parts by weight of an ultraviolet absorber (E) is molded. The spectacle lens has a total light transmittance of 85.0% or more at a thickness of 1.5 mm of the spectacle lens, a spectral transmittance of 400 nm of 2.0% or less, and a birefringence reduction rate. A spectacle lens characterized by being 5% or more. [Effect] Since the spectacle lens of the present invention is excellent in transparency, mechanical properties, heat resistance and hue stability, the hue may change or the resin itself may deteriorate even during the molding of the lens. In addition, UV rays that are harmful to human eyes can be cut efficiently. [Selection figure] None |
