WELBUILT Gradient Retro Square Sunglasses (60) (For Men, Brown)

Fit The way your sunglasses fit not only makes them look better, but it can also affect how effective they are at blocking out harmful UV rays. A well-fitting pair of sunglasses should fit snugly on your head without being too tight or uncomfortable. The center of the lens should line up with the center of your eye, and the frames should not be so wide that they let UV rays in on the sides. This can be just as harmful to your eyes as direct sunlight. 2.Shape There are several shapes of sunglasses available, including the more popular aviator, wayfarer, cat eye, and wraparound styles. For the most part, the shape you choose is an aesthetic choice. Find a shape that you like and that looks good with your facial features. For certain activities, however, the shape of your sunglasses can help protect your eyes. Athletic sunglasses, for instance, typically have a slim wrap design that fits snugly against your face and blocks UV rays from all angles. This reduces risks as you play 3.UV protection It should be clear by now that UV protection is the number one function of your sunglasses, but it is important to know what to look for when you are shopping for a pair. Make sure your sunglasses offer 100 percent UV protection. In addition, you can take even better care of your eyes by choosing sunglasses with polarized and anti-reflective lenses to reduce glare. 4.Material Most sunglasses are made out of Low grade Metal, especially the lenses. But the type of Metal they are made out of can make a huge difference. High Grade Metal are less likely to break or shatter and injure your eyes. Poly carbonate is both durable and lightweight and is common in both lenses and frames.
