Title:
キャリア及びフレネル膜を備える眼科用レンズの表面を決定する方法及びそのような表面を備える眼科用レンズ
Document Type and Number:
Japanese Patent JP6431843
Kind Code:
B2
Abstract:
Method for defining one face of an ophthalmic lens, having a surface formed by superposing a Fresnel layer and a continuous surface referred to as the “carrier”. Also disclosed is an ophthalmic lens comprising such a face. The method allows a Fresnel layer to be defined that compensates for geometric effects induced by a variation in the curvature of the carrier on the light incident on the face of an ophthalmic lens. This method is particularly useful when the curvature of the face of the ophthalmic lens is adapted to facilitate fitting it into a spectacle frame.
