Reading list: What is the power of sunglasses?
The “power” of sunglasses does not mean eyesight number like normal glasses. Instead, the power of sunglasses refers to how well they protect your eyes, block UV rays, and reduce glare from sunlight. Good-quality sunglasses have UV protection power, usually written as UV400, which means they block 100% of harmful UVA and UVB rays. This protection power keeps your eyes safe from long-term damage, headaches, and strain, especially when travelling or riding in strong sunlight. Some sunglasses also come with polarized lenses, which have the power to cut glare from roads, cars, and water surfaces, giving you clearer and more comfortable vision. A few models even have photochromic power, meaning the lenses automatically get darker outside and lighter indoors. On SunglassesVilla.in, every pair—whether sunglasses for men, sunglasses for women, premium sunglasses, or even budget options like sunglasses under 499 and sunglasses under 999—comes with proper UV protection mentioned clearly. So, when we talk about the power of sunglasses, we simply mean how strongly they protect your eyes, reduce glare, and make outdoor vision more comfortable. Choosing sunglasses with proper UV400 power is always the best way to keep your eyes safe and stylish at the same time.
