Optical Lens For Correcting Color Vision

Patent No. EP3685219 (titled "Optical Lens For Correcting Color Vision") was filed by Essilor on Sep 19, 2018. The application was issued on Nov 22, 2023.

Patent Summary

Optical lens for correcting color vision deficiency through selective transmission characteristics, particularly for individuals with color vision deficiency. The lens comprises a selective filter, like an absorptive magenta dye, which is able to cut in the green of the visible spectrum. The filter is combined with a color-balancing component to partially offset the pinky appearance of the lens. The lens achieves a transmission curve characteristic of 8-18% in the visible spectrum, with a specific transmission curve that optimizes color perception while maintaining cosmetically acceptable appearance.
