摘要:
A method produces a spectacle lens that provides both ophthalmic vision and an additional type of vision. The method includes two consecutive steps consisting of calculating a rear surface and a front surface of the lens. The additional vision type corresponds to the perception of a light that is conveyed between the front and rear surfaces by an insert built into the lens. The rear surface of the glass is initially calculated to provide a correction of the additional vision type, and the front surface is calculated to correct the ophthalmic vision. The two surfaces of the glass therefore have complex shapes, which simultaneously reduce the optical aberration levels for both types of vision.
