While sunglasses are often considered a stylish accessory, their significance goes beyond fashion—they play a crucial role in safeguarding your overall eye health. The sun emits ultraviolet (UV) radiation, an invisible form of energy that can have harmful effects on our eyes. Prolonged exposure to UV radiation may lead to various eye conditions such as cataracts, macular degeneration, and photokeratitis (sunburn of the eye), ultimately resulting in vision loss and other serious problems.
Sunglasses function by either absorbing or reflecting UV radiation before it reaches our eyes. The lenses of sunglasses are crafted from materials with the capability to filter out different wavelengths of light, including UVA and UVB rays. The level of UV radiation blocked depends on the type of lenses. While the American Optometric Association recommends sunglasses that block 99 to 100 percent of both UVA and UVB radiation, not all sunglasses offer this level of protection. When buying sunglasses, carefully check the labels and opt for those providing UVA and UVB protection. If you wear prescription glasses, consider investing in a pair of prescription sunglasses for driving and outdoor activities.
Beyond shielding our eyes from UV rays, sunglasses offer additional benefits. They reduce glare, enhance visual comfort, and improve visual clarity. Sunglasses with polarized lenses, in particular, are effective in minimizing glare, especially during activities like driving or being outdoors near water or snow. Individuals with light sensitivity or specific cataracts may also find relief and improved vision by wearing sunglasses.
As you select your sunglasses for the upcoming spring season, prioritize a style that ensures adequate UV protection. Remember to wear them whenever you're outdoors, especially during peak sunlight hours. Explore our optical collection, where we offer a range of prescription and non-prescription sunglasses.
