Gray lenses can absorb any color spectrum in a balanced manner. After wearing the glasses, the scenery you see will only become darker and there is no obvious chromatic aberration. Brown lenses can filter out a lot of blue light, which can improve visual contrast and clarity. Try not to choose red lenses, because red lenses have the worst absorption effect of ultraviolet rays.

The dangers of red lenses to the eyes

Not only do they like to wear sunglasses, but they also hope that the styles of sunglasses are new and innovative, and the lens colors are colorful. It is worth noting that it is best not to wear sunglasses with red lenses, otherwise eye diseases such as cataracts will be recruited. In recent years, the cataract patients received in the ophthalmology clinic have shown a trend of getting younger, and every summer is the high incidence of the disease. The reason may be caused by sunglasses. The human body has an instinctive response to self-protection. When the eyes are exposed to strong light, the pupils will naturally shrink, and the intensity of the ultraviolet rays passing through will also be weakened. Although sunglasses do not have the effect of isolating ultraviolet rays, the pupils shrink much less because of the weak light after wearing them. At this time, in the face of the invasion of ultraviolet rays, the eyes are wide open, and the damage can be imagined. In clinical practice, some patients often cause cataracts and other related diseases because of wearing inappropriate or inferior sunglasses. Therefore, everyone should choose sunglasses produced by regular manufacturers. The color can choose medium-deep green, gray, brown, etc. It is best not to choose red because red lenses have the worst ultraviolet absorption effect and can not protect the eyes.
