Sun glasses protect the eyes from the effects of ultraviolet rays, reducing the risk of diseases such as sunburn, cataracts or macular degeneration.
When the skin is exposed to excessive sunlight, ultraviolet light can lead to sunburn, which is more serious than skin cancer. But most people ignore their eyes and underestimate the importance of sunglasses. In fact, you need to wear sunglasses regularly, both in winter and in summer.
To keep your eyes healthy, experts recommend that you use 99-100% UVA and UVB protection and 75-90% reduction in visible light. Give priority to protection when choosing sunglasses, not styles. Lastly, remember that UV rays not only come from the sun but are reflected on many other surfaces such as water, concrete and cars.!
