All our sunglasses have UV-400 polarized protection. No matter it is bright sunshine days or those overcast cloudy days, eyes protection from sunlight and harmful UV light should never be neglected, especially for people normally wear eyeglasses. Wearing a pair of normal eyeglasses with no anti-glare coating is inconvenient during outdoor activities like a long drive. It’s hard to see clearly with the glaring in our eyes. A pair of prescription sunglasses can usually be expensive for people who have strong prescriptions. On Joopinfashion.com we offer high-quality RX shades with low-cost prices that will never run out of your budget.
