What Is The Biggest Hazard Of Inferior Sunglasses?
- Sep 19, 2018 -


Some people may ask, although the inferior sunglasses are cheap, but they are better than not wearing them? Wrong! If the quality of the sunglasses is unqualified, it is better not to wear them. There are two reasons for this:

 

1. Permanent eye injury

Bring sunglasses, the light is dimmed, so the pupils of the person will increase, but because your sunglasses can not block the ultraviolet rays, it is equal to a large amount of ultraviolet rays to take in the large pupil, which is more than hurting the eyes! And the damage of ultraviolet rays to the eyes is cumulative and irreversible.

 

2. Damage to vision

This is mainly a question of workmanship. General glasses, whether it is sunglasses or other glasses, have a reasonable optical index design, including sphericality, prismatic degree, etc. If the design is unreasonable, it is easy to visually deform the object, causing the eyes to double fatigue, and the vision will decrease in the long run.

 

Good sunglasses are completely UV-resistant in function; optically reduce visual distortion and protect eyesight; comfortable and strong in wearing, and high design and brand power, so there are a large number of people who are willing to pay a high price!
