Sunglasses are not only an accessory to enhance your appearance but also a product that protects your eyes from harmful UV rays. But how exactly do glasses protect your eyes? Let's find out together!
Mirror coating
Eye protection often has a mirror coating, which can reflect light away from your eyes. This helps filter sunlight and prevent it from reaching your eyes. Thanks to that, you can avoid glare, eye strain and squint.
UV protection layer
In addition to a mirror finish, high-quality sunglasses also have a UV coating. Although a mirror finish can reflect sunlight back, it may not filter out all the UV rays that reach your eyes. By adding UV coating to the mix, sunglasses can best block harmful rays from damaging your eyes.
Anti-reflective coating
Anti-reflective (AR) coating creates clearer images when you are wearing sunglasses. It does this by preventing light from reflecting off the back of your sunglasses. This ensures that you don't see any annoying reflections when wearing sunglasses.
Polarized lenses
Not all sunglasses are polarized, but the best ones are. Polarized sunglasses provide the best protection while improving overall visibility. They reduce glare by blocking high-intensity light, and they enhance contrast to avoid eye strain. Polarized lenses are especially useful when you're walking on water or snow, where reflected sunlight is even harsher.
Harmful Effects of Going Out in the Sun Without Wearing Eye Protection Glasses
Not wearing glasses when going out in the sun can have many serious effects on your eye health and your overall health:
Accelerates the aging process: When the eyes are directly exposed to harmful UV rays from the sun, the aging process will occur faster. UV rays damage skin cells around the eyes, causing loss of elasticity and leading to the appearance of wrinkles and brown spots.
Increased risk of eye diseases: Prolonged exposure to sunlight can cause sunburn on the surface of the eyeball, leading to macular degeneration and even eyelid cancer. UV rays can seriously damage the cellular structure of the eye, increasing the risk of serious diseases.
Causes cataracts: Ultraviolet rays in sunlight directly attack the eyes, causing damage to the eye lens and retina. This changes the structure and composition of proteins in the lens, leading to cataracts. Cataracts are one of the main causes of blindness if not treated promptly.
Impaired vision: Dust, polluted water sources and toxic chemicals from the environment also contribute to eye damage. These substances affect the eyes, causing accumulation of harmful oxidants, destroying the endothelial cells of the retina and damaging visual cells. As a result, vision will decline over time.
To protect your eyes and overall health, it is extremely important to wear eye protection when outdoors in the sun. If you still don't know which glasses to buy, you can refer to the product at the link: Sunglasses .
