The blue light and green light and yellow light are mixed with white light.Green light and yellow light have less energy, less irritation to the eyes, short Blu -ray waves, and high energy.For our normal people, blocking blue light for a long time is the most effective way to reduce damage. The use of anti -blue -light lenses can effectively solve this. Ordinary ultraviolet lenses can only filter ultraviolet rays without filtering blue light. Invention content [0003] The purpose of the present invention is to provide a lens anti -blue -light film. This anti -blue light film can not only effectively isolate ultraviolet rays, but also filter blue light. [0004] In order to achieve the above goals, the present invention uses the following technical solutions: [0005] ...
