摘要： Described are photochromic ocular devices such as contact lenses and intraocular lenses made of an organic polymeric material and at least one photochromic material capable upon exposure to actinic radiation to change from a less ultraviolet radiation absorbing unactivated form to a more ultraviolet radiation absorbing activated form. The photochromic ocular device is capable upon exposure to actinic radiation to exhibit a ratio of greater than 0.5:1.0 of increased ultraviolet radiation absorbance to increased visible radiation absorbance as measured in the Ultraviolet Photochromic Performance Test described herein.

For example, various non-limiting embodiments disclosed herein provide a photochromic material, such as an indeno-fused naphthopyran, which comprises a group that extends the pi-conjugated system of the indeno-fused naphthopyran bonded at the 11-position of thereof. Further, the photochromic materials according to certain non-limiting embodiments disclosed herein may display hyperchromic absorption of electromagnetic radiation as compared to conventional photochromic materials and/or may have a closed-form absorption spectrum that is bathochromically shifted as compared to conventional photochromic materials. Other non-limiting embodiments relate to methods of making the ophthalmic devices comprising photochromic materials.

摘要： Described are contact lenses having photochromic materials within the central or pupillary area of the lens and methods for manufacturing such lenses. In one method, a photochromic amount of at least one photochromic material is added to the pupillary region of a casting mold containing a polymerizable monomer that can be at least partially cured before and/or after the addition. Another method involves providing an amount of polymerizable photochromic monomer for the pupillary region and an amount of polymerizable non-photochromic monomer for the remainder of the contact lens in a casting mold. The photochromic and non-photochromic monomers can differ by their degree of polymerization, viscosity and/or density.
