Do blue light glasses really protect your eyes?
Scientists at the University of Kansas in the United States summarized the results of studies around the world in the past 30 years and pointed out that there is not enough evidence in human trials to prove that blue light is related to macular degeneration, and there is no test showing that blocking blue light glasses are related to macular degeneration. Moreover, experts from the University of S?o Paulo in Brazil have observed after five years that patients who use anti-blue light intraocular lenses after cataract surgery have no difference in the incidence of macular disease compared with those who use ordinary intraocular lenses.

Why do glasses with the same prescription feel different?
The old glasses 'remodeled' your eyes. Sometimes, all data on optometry and processing are accurate, and the spectacles equipped are in full compliance with the prescription for optometry, or the power of new spectacles is exactly the same as that of the old spectacles, but you will still be dizzy when wearing the new spectacles. This is because the old glasses 'remodeled' their eyes during long-term wear. For example, the old glasses used by some people have been severely deformed. The temples are no longer in the same plane, and the optical center area of the lens will deviate from the interpupillary distance measured by the glasses at that time. However, the wearer does not mention this situation, and the eyes gradually adapt to this kind of deviation. After putting on a new pair of glasses, you will not adapt to them.
How to test a blue-light lens?
Look at the lens. High-quality anti-blue glasses do not interfere with the line of sight, with high transmittance. The light transmittance is very high, and the visual clarity is higher, which does not affect the visual quality, quality of life, contrast sensitivity, and color discrimination.
