Sunglasses come in a variety of styles and incorporate different tools to help protect your eyesight from the sun’s powerful ultraviolet (UV) rays.
Depending on your exposure to UV rays, you may experience temporary or permanent vision issues. For example, if you experience excessive UV exposure over a short period of time you can get photokeratitis, or “sunburn of the eye.” This disorder can be painful, but the effects are temporary.
But the longer you are exposed to solar radiation, the more likely you are to develop more serious issues like macular degeneration, cataracts, or several other eye disorders. Individuals who spend plenty of time outdoors or live in areas where there is high UV exposure.
These issues are why you need to take proper precautions when you are exposed to sunlight or other sources of UV rays. Even on cloudy days or in the winter months, UV radiation is a concern you should protect against.
When selecting a pair of sunglasses, you should look for them to protect against 99% of UVA and UVB radiation, two forms of UV light.
If a pair of sunglasses protects against both forms, they will be properly labeled. The tint on your lenses can also help provide better visibility and comfort. But tint is not necessary to protect against UV radiation.
Safety glasses or eye protection will also be labeled appropriately if they protect against powerful UV rays. If you work with lasers, tanning beds, or welding this is an important feature to check on before selecting the best eye protection.
Even some contact lenses provide UV protection for daily use or high exposure. But even if you wear contact lenses with UV protection, you should still wear sunglasses to adequately protect your eyes.
