Anti-blue light glasses do not prevent myopia. The principle of anti-blue light glasses is to filter out the harmful blue light content in the ambient light through a special coating on the lens. Their main function is to prevent harmful blue light from causing cumulative damage to the retina and lens, which has the effect of reducing the risk of cataracts and macular degeneration in the future.
Anti-blue light glasses cannot relieve visual fatigue, nor can they control the growth of myopia or prevent myopia from occurring. The main target is refractive error patients who use computers, cell phones and other electronic products for a long time, which can play a role in filtering the harmful blue light emitted by the electronic screen, while protecting the eyes.
However, wearing anti-blue light glasses will make some patients see the scenery yellowing, forming a certain color difference, for patients engaged in photography, art and other work will have a certain adverse effect.
Whether patients need to wear anti-blue light glasses at present, need to go to the hospital ophthalmology examination, the doctor to make guidance.
