Have You Noticed the "SHELF LIFE" of Sunglasses?
Long time exposure to sunlight will reduce the anti ultraviolet ability of the lens. If the lens is not replaced for a long time, it is easy to cause corneal damage and vision problems.
According to the research, exposure to the sun may degrade your sunglasses, make the lenses lighter, and reduce the resistance of the lenses, that is, the shatterproof index of the lenses.
The World Health Organization has published an article "ultraviolet radiation and human health", which points out that 5% of the 18million people who are blind due to cataract in the world every year are caused by ultraviolet radiation. UV can also cause other serious eye diseases - keratitis, retinal damage, cataract, macular degeneration, snow blindness, etc. Therefore, sunglasses that can filter ultraviolet rays have become an important equipment to protect our eyes in the sun.
