There are many brands of anti-blue glasses on the market, and the prices are uneven. Mainly to understand the principle of anti-blue glasses. Blue light is not completely harmful. What is really harmful is blue light with a wavelength of 440-470nm. Good anti-blue glasses only prevent this harmful blue light, not all light. Therefore, it is very necessary to choose a pair of good anti-blue glasses, otherwise, buying a pair of anti-blue glasses that can resist regardless of injury will not only protect your eyes, but also hurt your eyes.
We recommend a brand of anti-blue glasses, Guardview Super Anti-blue Bian Shi Glasses, with Bian Shi, a medical device material approved by the State Administration of Medicine, added to the frame. Glasses have applied for dual patents of invention and appearance, and passed the inspection of Beijing Quality Inspection Institute, the highest national inspection institution, and are qualified products. I believe that there is no problem in the quality of the products that can apply for patents and pass the testing of the highest national testing institutions.
