Polymeric compositions have photochromic and blue-light filtering ability and are useful in the manufacture of ophthalmic medical devices. The polymeric compositions comprise a photochromic material incorporated into polymeric host materials and are activatable by blue light having a first wavelength range to become photochromic, and are thereby capable of absorbing blue light in a second wavelength range. Methods of making the compositions comprise incorporating a photochromic material into a polymeric host material.
聚合物组合物具有光致变色和蓝光过滤能力,并可用于制造眼科医疗器械。该聚合物组合物包括将光致变色材料并入聚合物基材料中,可以通过第一波长范围的蓝光激活变成光致变色,并且因此能够吸收第二波长范围的蓝光。制造该组合物的方法包括将光致变色材料并入聚合物基材料中。
