The name "sunglasses" comes from its fundamental role as a tool for protecting the eye. In daily life, the eyes cannot avoid direct or indirect contact with the sun, it is difficult to avoid UV damage. Ultraviolet damage to the lens of the eye is cumulative and irreversible, and the lens absorbs ultraviolet light for years to form an irreversible turbidity, which is easy to cause cataracts, macular degeneration and other diseases, resulting in permanent eye damage.

So sunglasses near me now are not just for summer. As long as the light is strong and bright enough to make your eyes feel burning and sore, you need to wear sunglasses to avoid UV damage. In particular, people who work outdoors for a long time, or live in areas where ultraviolet radiation is more intense, such as the plateau, need to develop the habit of wearing sunglasses to shield the sun.

For sunglasses, the UV index refers to the effect of filtering out ultraviolet light, that is, eliminating light in the 280-400 nanometer band. UV means to prevent ultraviolet light below 380 nanometers, and UV400 means to prevent ultraviolet light below 400 nanometers, that is, 100% UV protection. A pair of high-quality sunglasses can both completely block UV rays and maintain a relatively high transmittance of visible light.
