Only you can decide which of this year's sunglass trends will work for you. Here are a few guidelines to buying the right lenses: Mirrored lenses have a thin layer of metallic applied to lens that may reduce visible light to reach eyes, but not UV rays. Gradients are tinted lenses that are darker on the top fading to no tint on the bottom. Polarized lenses cut glare from smooth surfaces such as water, snow or pavement. Photochromic lenses are sun-sensitive and transition from light to dark shade according to light conditions. Tints are a color called "neutral density gray" and change shade but not color perception.
Okay, you don't want to wear sunglasses in the dead of night. That's just dangerous. But when the sun is setting, shift your dark-lensed glasses to sunglasses with lighter tints. Beiges go well with whatever outfit you're wearing. If you're in all black, go for a grey tint or give yourself a boost of color by choosing tints that are a little more whimsical, such as purple or blue.
Photochromic lenses automatically lighten and darken as light changes. They are often used in prescription lenses, but come in sunglass lenses too. Most Photchromic lenses do not darken as much as sunglasses, and they often do not get dark enough inside cars. Thus, they cannot completely replace sunglasses.
Most sunglasses come in three lens types, plastic, polycarbonate, or glass. Glass lenses are better for many situations, and should not distort as much as cheap plastic lenses. It is also heavier than the other materials. You can see high quality glass lenses in the Serengeti Trek Sunglasses. Polycarbonate lenses are more durable, and perfect for kids' sunglasses, many extreme sports, and in any situation where sunglasses could be damaged or broken by work or play. They also come in many designer brand shades like Christian Dior Sunglasses. Plastic lenses usually come in less expensive discount sunglasses, like the Ray-Ban Outsiders Wayfarer Sunglasses, which although more susceptible to scratching and breaking, still offer high quality for the money.
Before you buy a set of sunglasses, test the lenses for distortion and/or imperfections by looking through the lenses at a straight edge you hold at arms' length. If the lenses have no imperfections, you should continue to be able to see that straight edge without any curve or distortion. Test the lenses if you think the sunglasses might be a copy or imposter.
Sunglasses come in many different colors and tints for a reason. They all protect your eyes from glare differently, and they all help you see some items more clearly. What tint is right for you depends on where you will be using your sunglasses, and your own eyes. Try tints before you buy to get the best results for your eyes.
