High energy light blocking compounds and ophthalmic devices containing these compounds are described. In particular, a hydroxybibenzobenzotriazole structure with polymerizable functionality is described, which blocks high-energy light and is visible and transparent. The hydroxybiphenylbenzotriazole structure can be incorporated into ophthalmic devices, such as hydrogel contact lenses, to protect the eyes from high-energy light radiation. |
