Abstract:
A method and coating used to prepare a photochromically-enabled bifocal ophthalmic lens. The coating is a high adhesive strength acrylate-based coating that contains a small quantity of a polycarbonate-based TPU. The coating is applied to produce an intermediate imbibable bifocal surface. A photochromic solution is subsequently imbibed by contact with the bifocal surface.
Abstract:
A method and coating used to prepare a photo chromically-enabled bifocal.ophthalmic lens. The method and equipment includes injection molding a single vision lens (10e), for example, from polycarbonate. The clamp opens vertically and the top insert (20) is exchanged for a bifocal mold (30) having a base curve similar to the single vision lens. The thermos et coating includes compounds from several acrylate classes, and is applied to the single vision lens. The coating may include a photochromic dye. The coating is also formulated to receive a photochromic solution through an imbibition process.
