Walking on the street, we often see many people wearing eyewear, especially sunglasses，include acetate sunglasses, Metal sunglasses, Titanium sungalsses, etc. But it is not known whether the sunglasses protect your eyes, whether the sunglasses have the function of preventing ultraviolet rays. However, wearing sunglasses without UV protection will not only not protect the eyes, but will also harm the health of the eyes. When the eyes are exposed to strong light, due to a kind of instinctive protection of the human body, the pupils of the eyes will consciously become smaller, blocking a large amount of ultraviolet rays from entering the eyes and harming the eyes. However, once you wear darker sunglasses, the pupils of your eyes will automatically expand in a dark environment, but the ordinary sunglasses do not have the effect of isolating ultraviolet rays. At this time, the intrusion of ultraviolet rays will greatly increase, which will cause damage to the lens and retina.
Therefore, when buying sunglasses, you must choose carefully, and you must not just look at the appearance and whether it matches with your own clothing and face shape. You must carefully look at whether the sunglasses protect you eyes.
Just as wearing sunscreen is the best way to protect your skin from the sun, wearing sunglasses is the best way to protect your eyes from UV damage. Studies have shown that long-term exposure to UV radiation can cause damage to retinas and increase the risk of developing cataracts or macular degeneration. To help keep eyes properly protected from the sun, follow these simple rules:
Wear high-quality sunglasses that offer 100% UV protection. Many famous brands of the Sunglasses offer superior lens technology that blocks out sun without affecting visibility.
Don't take off sunglasses in the shade. UV rays can reflect off other surfaces, so eyes are still at risk even if they are not directly exposed to the sun.
Fresh snow can reflect 80% of UV rays, so protective eyewear is important even in the winter. Sunglasses will do the trick, but skiers and snowboarders should wear UV protected goggles for the best results.
It is never too early to start practicing eye safety. Children's eyes are more sensitive than an average adult, so be sure they are always wearing the proper eyewear. It is also a good idea to keep children out of the sun during peak sun hours, typically between 10am - 2pm.
Why can sunglasses prevent ultraviolet rays?because during the manufacturing process of sunglasses, when the lenses are in a liquid state, materials that absorb ultraviolet rays are added to block ultraviolet rays. Many inferior sunglasses omit this link in the manufacturing process,It seems that it is no different from UV-resistant sunglasses, but it can't prevent the damage of UV rays to the eyes at all. Therefore, whether we buy acetate sunglasses, metal sunglasses or other types, we must pay special attention to the lenses that have good UV protection. So, when buying sunglasses, please buy sunglasses that can protect your eyes.
