Sunglasses elevate your look, but their real superpower is protecting your eyes from the sun’s ultraviolet (UV) rays. UVA rays penetrate deep, raising the risk of cataracts and macular degeneration, while UVB rays can burn the eye’s surface, causing photokeratitis. Long-term exposure without protection can even lead to skin cancer around the eyes. Quality sunglasses that block 100% of both UVA and UVB rays are a must, no matter the season—clouds don’t stop UV light from reaching your eyes.
Choosing the Right Pair: What to Know
Not all sunglasses are created equal. Look for UV400 labels or 100% UV protection—dark lenses alone won’t cut it without proper coatings. Polarized lenses reduce glare, perfect for driving or water sports, while wraparound styles block peripheral rays. Lens materials matter too: polycarbonate is lightweight and impact-resistant, ideal for active lifestyles, while glass offers superior clarity but is heavier. Kids need sunglasses even more—their eyes let in more UV light, with up to 80% of lifetime exposure happening before age 18. Next time you shop, prioritize protection over price; your future vision depends on it.
