The present invention relates to a polycarbonate resin having a specific melt index capable of selectively and effectively blocking ultraviolet rays while having excellent stiffness and transparency, and a method for producing a polyhydroxyalkanoate resin composition comprising a 2-hydroxybenzotriazole derivative and a hydroxyphenyl-1,3,5-triazine A polycarbonate resin composition for a lens comprising at least one compound selected from the group consisting of a benzoxazole derivative and a coumarin derivative, and a polycarbonate resin prepared therefrom. Accordingly, the polycarbonate resin composition has not only superior rigidity and transparency but also has an improving effect on ultraviolet rays and an ultraviolet shielding effect, and the polycarbonate resin produced therefrom has various forms such as sports goggles, It can be easily applied to lens material. |
