Colored glasses are not equal to sunglasses
Red, yellow, purple, green lens is sunglasses? In the past, the color of sunglasses was mainly dark brown and dark blue. In the past two years, colorful colored glasses appeared on the market. Some people think that colored glasses are sunglasses, and they are particularly cool to wear, so they are fashionable to choose. Actually, this is a misunderstanding.
Experiments have shown that colored glasses have a certain protective effect on the eyes because of their different colors, but they lose the function of sunglasses because they cannot block ultraviolet rays.
If you wear colored glasses without anti-UV function, it is more dangerous than not wearing sunglasses. Because the human body has a self-protecting instinct, when the eyes encounter strong light, the pupil will naturally become smaller, so that the ultraviolet energy entering the eyes is reduced. Wearing glasses without anti-UV function will enlarge the pupil, and this kind of glasses does not have the effect of isolating ultraviolet rays. At this time, the eyes are equal to the opening of the portal, allowing ultraviolet rays to invade, and the energy is greatly increased, and the damage to the eyes can be imagined.
