1. Permanently hurt the eyes
Wearing sunglasses, the light becomes darker, so people’s pupils will increase, but because your sunglasses can’t block ultraviolet rays, it means that a large amount of ultraviolet rays are ingested into enlarged pupils, which hurts the eyes even more than not wearing them! Moreover, the damage of ultraviolet rays to the eyes is cumulative and irreversible.
2. Harm eyesight
This is mainly a matter of workmanship. General glasses, whether it is sunglasses or other glasses, have a reasonable design of optical indicators, including sphericity, prism, etc. If the design is unreasonable, it is easy to deform the eyes, causing double fatigue of the eyes, and vision loss in the long term.
Good sunglasses are functionally capable of preventing ultraviolet rays; optically reduce visual distortion and protect eyesight; they are comfortable and sturdy to wear, as well as tall design and brand power, so a large number of people are willing to pay a high price!
The End
Thanks for watching!
