Exposure to ultraviolet (UV) radiation can cause corneal sunburns and other eye problems. This is why Park Slope Eye emphasizes the importance of wearing sunglasses.
As we observe UV Awareness Month this May, your family eye care specialists share important things to consider when looking for quality sunglasses.
UV radiation emitted by the sun comes in two forms: UVA and UVB. UVA rays are often linked to macular and retinal damage that may cause central vision changes, while UVB rays can cause sunburn.
When buying sunglasses, one of the first things you should consider is their ability to provide UV protection. Your eye doctor suggests looking for a sticker or label on the glasses that states they provide UV400 or 100% UV Protection. This means the sunglasses can block up to 400 nanometers of both UVA and UVB rays for your optimum visual safety.
Oversized sunglasses are not only fashionable, but they also provide more protection from the sun’s UV radiation. Bigger lenses give you more coverage, reducing your risk of developing UV-related vision problems.
It is a myth that the darker your sunglasses are, the better protection they provide. The color of the lenses doesn’t matter; all you need to do is check for the 100% UV protection sticker. If there’s isn’t one, your eye care specialist can help evaluate the sunglasses for you.
Apart from wearing quality sunglasses, applying sunscreen and wearing wide-brimmed hats can also provide added protection from the sun’s harmful UV rays.
