Photochromic blue light filtering materials and ophthalmic devices |
摘要 |
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.
