Latest Patents
Mignen's latest patents include advancements in multifocal ophthalmic lenses. These lenses feature a bifocal design where the convex front surface is divided into an upper part for distant vision and a lower part for reading. The upper part has a first spherical surface with a greater radius than the second spherical surface used for reading. A zone of curvature continuity connects these surfaces, ensuring a smooth transition along at least one meridian of the lens. In the case of trifocal lenses, a third crescent-shaped spherical surface is added, providing an intermediate radius between the first and second surfaces. Additionally, he has developed photochromic ophthalmic lenses made from organic materials. These lenses incorporate at least one layer of photochromic mineral glass, which imparts unique photochromic properties. This layer may consist of woven fabric made from photochromic mineral glass fibers, ensuring compatibility with the organic material of the lens.
