Various non-limiting embodiments disclosed herein relate to ophthalmic devices comprising photochromic materials having extended pi-conjugated systems. 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.
L'invention concerne divers modes de réalisation non limités relatifs à des dispositifs ophtalmiques contenant des matières photochromiques à systèmes pi-conjugués étendus. Par exemple, divers modes de réalisation non limités présentés offrent une matière photochromique, notamment du naphtopyrane indéno-fusionné, comprenant un groupe qui étend le système pi-conjugué du naphtopyrane indéno-fusionné lié au niveau de sa position 11. En outre, les matières photochromiques de certains modes de réalisation non limités de l'invention peuvent présenter une absorption hyperchromique du rayonnement électromagnétique comparable à des matières photochromiques classiques et/ou peuvent posséder un spectre d'absorption de forme fermée qui est bathochromiquement décalé par rapport aux matières photochromiques classiques. D'autres modes de réalisation non limités concernent des procédés de fabrication de dispositifs ophtalmiques contenant des matières photochromiques.
