Why are blue light glasses yellow?

The material of the lens makes it turn yellow. If it's just blue and the lens is yellow, that's the material itself. Blue light glasses can weaken blue light entering human eyes. Blue light is mainly produced by mobile phones and computers in life. The blue light on the electronic screen is unchanged, so a film can only be designed on the lens to absorb blue light. This can effectively reduce blue light. The complementary color of blue light is yellow, so the yellowing of the anti-blue lens is normal. The material of an anti-blue light lens can effectively shield the blue light. If the blue light is removed from the white light we usually see, it will show yellow, which is a normal phenomenon.



Adolescents and adults with myopia

Teenagers have heavy learning tasks, and excessive eye use is the norm, so pseudomyopia is the majority. And many of them have false and true myopia coexistence. As adolescents grow and hair, the eyeballs are also developing, and the wheelbase may be further lengthened, so myopia will continue to progress and deepen. The use of mydriatics by adolescents can force the ciliary muscles to relax and eliminate pseudomyopia. But after the pupil is dilated, the ciliary muscles will also lose their ability to adjust, changing from 'nearsightedness' to 'hyperopia', which will delay daily learning. And after the efficacy of the drug has passed, if you continue to use your eyes unscientifically, pseudomyopia will still occur. Therefore, the mydriatic agent is only used as an auxiliary method to eliminate false myopia when wearing myopia glasses, not as a treatment method for myopia.

Adult myopia is based on true myopia. In addition, the eyeballs of adults will no longer develop, so the degree of myopia is relatively fixed and rarely changes.
