Title: Innovations in Ophthalmic Lenses by Claire Rossier
Introduction
Claire Rossier is a prominent inventor based in Paris, France. She has made significant contributions to the field of ophthalmic lenses, holding 2 patents that showcase her innovative spirit and dedication to improving vision solutions.
Latest Patents
One of her latest patents is a set of progressive multifocal ophthalmic lenses. This invention concerns a set of lenses, each featuring a first progressive multifocal surface and a second preferably spherical surface. The invention aims to define the set of lenses based on their optical characteristics, particularly focusing on wearer power and oblique astigmatism in worn conditions. To achieve this, Rossier defines an ergorama that associates each sight direction with a target object point and a specific power. This ergorama provides a power target for lens optimization and is utilized in a radii plotting program to calculate the optical characteristics during the optimization process. The set of lenses ensures substantially identical optical performances for a given addition, regardless of the power of the far vision reference point.
Another notable patent is a multifocal ophthalmic lens that comprises a far vision region, a near vision region, and an intermediate vision region. This lens features a high near vision region and a wide vision field in all regions. The progression is gentle, with the distance between the mounting center on the lens and the point where power addition is 85% higher than at a far vision control point being less than 16 mm. Additionally, the maximum cylinder within a 20 mm radius circle centered on the lens's geometrical center is maintained at a low value.
