Abstract
Various non-limiting embodiments of the present disclosure relate to ophthalmic devices comprising photochromic materials comprising a reactive substituent. For example, the present disclosure contemplates ophthalmic devices comprising photochromic materials, such as photochromic naphthopyrans and indeno-fused naphthopyrans having a reactive substituent comprising a reactive moiety linked to the photochromic naphthopyran by one or more linking groups. In certain non-limiting embodiments, the reactive moiety comprises a polymerizable moiety. In other non-limiting embodiments, the reactive moiety comprises a nucleophilic moiety. Other non-limiting embodiments of the present disclosure relate to methods of making the photochromic ophthalmic device, wherein the photochromic ophthalmic devices comprise the photochromic naphthopyrans described herein.
