Appendix: We have talked so much about the "plastic surgery effect" of sunglasses, so how should we choose the most appropriate sunglasses?

1. Check whether it has UV protection function.

We all know that excessive ultraviolet rays can damage human eyes. Among the ultraviolet rays of the sun, "UVB" can reach the lens, while "UVA" can reach the retina directly. When it comes to sunglasses, some people think they are "colored glasses". In fact, not all "colored glasses" can block ultraviolet rays, so when choosing sunglasses, you must check whether they have UV protection. Generally speaking, in terms of the effect of UV protection, "100% UV absorption" > "UV400" > "UV" "UV protection".

2. Green, brown and gray are better choices for lens colors.

Sunglass lenses come in many colors. When choosing, green, brown, and gray are recommended. These three colors of sunglasses lenses have a relatively good effect in absorbing ultraviolet rays. In addition, you also need to see whether the surface of the lens is delicate and smooth enough. The entire lens should have no ripples, no flaws, no bubbles, and even scratches.

3. Pay attention to the comfort of weight.

The weight of the sunglasses should be evenly distributed on the nose and ears, ensuring that the frames do not pinch the bridge of the nose or rub the ears. When wearing the sunglasses, the eyelashes should not touch the frames.

4. If you have special activities, it is recommended to choose polarized sunglasses.

Polarized lenses are currently recognized as the most suitable lenses for driving. They are also suitable for other outdoor activities such as cycling, skiing, fishing, etc. Polarized sunglasses can reduce strong light and stray light, reduce the glare caused by diffuse reflections caused by the road or water surface, and improve visual clarity.
