More importantly, after wearing sunglasses, due to the dimming of the light, people's pupils will be released to varying degrees, *** sunglasses can block 100% harmful light, so the eyes will not be harmed, but poor quality glasses can not block harmful light, after the pupils are dilated, they absorb more ultraviolet rays, etc., which is more harmful to the eyes, so it is recommended that you must buy *** big brands when you buy sunglasses, in principle, sunglasses below 500 yuan are nothing good.

It's true that you can bring it, but poor quality glasses hurt your eyes because of the rough workmanship. Since you want to bring it, you should buy a good one.

4. Stimulate the quality of Hermiyi's lenses: The quality of the lenses will affect the performance and service life of sunglasses. High-quality lenses should have excellent optical properties, effective UV protection, abrasion and scratch resistance, etc.
