Structure of zoned spectral control lenses

Abstract

This invention relates to a structure for a zoned spectral control lens. The structure includes an eyeglass lens with a peripheral portion for connecting to an eyeglass frame. The eyeglass lens includes an upper filter region, a transition filter region, and a lower filter region arranged in a height direction. The blue light blocking rate of the lower filter region is greater than that of the transition filter region, and the blue light blocking rate of the transition filter region is greater than that of the upper filter region. This allows the upper filter region to correspond to the distance viewing area, and the lower filter region to correspond to the near viewing area. By creating different spectral transmission characteristics in different regions of the eyeglass lens, the spectral control effect is achieved to meet the user's spectral needs at different viewing distances, reducing blue light stimulation, improving visual comfort, and enhancing the nighttime viewing experience.

Claims
