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.
