Technical Field

Background
When the sunlight is projected on the road surface or water surface, the sunlight forms scattering, directly stimulates eyes, makes the eyes feel dazzling and tired, and cannot look for objects for a long time. Particularly, when driving a car and carrying out outdoor recreational activities, the driving device not only influences the working and recreational moods of people, but also influences the judgment of people on the object image to cause danger; when the eye drops under the direct irradiation of sunlight for a long time, the eye drops rapidly, and myopia, hypermetropia, astigmatism or cataract is formed. Although the existing polarized glasses can filter the scattered light in the light beam, only the light in a fixed direction passes through the existing polarized glasses, so that the eyes receive the incident light in the same direction, and the scenery looks soft and not dazzling; however, since the polarized glasses can only pass light in a fixed direction, the transmittance is lost by at least 40%, which results in a dark sight. In addition, there are also dyed glasses or color-changing glasses to solve the above problems, however, both the linear polarizer and the dye (the color change itself is also a dye absorption) can absorb a part of the light totally, and the strong light-reflecting object can not be selectively absorbed.
