Protection from UV
One contributing factor to eye disease is ultraviolet radiation. This is why it is important to choose a pair of sunglasses that protect you from the harmful effects of the sun and UV rays. Just because your glasses have a dark tint doesn’t mean that you are protected from UV rays. Check the UV rating before you make a purchase.
What the Sunglasses Are Made From
Generally speaking the heavier the sunglasses, the higher quality they will be. You want to ensure that the material that they are made from will last a long time and be able to resist the constant knocks that sunglasses typically take. Although you might pay more for high quality sunglasses, it will still be cheaper than replacing cheap sunglasses every time you drop them.
Tints are the colors that are applied to sunglasses lenses to help reduce the light that comes into contact with the eyes. The particular tint you choose is partly up to your personal taste. However, different tints will have a different effect on brightness and glare, and may distort color differently.
As an example, gray tints reduce glare and don’t distort the color. On the other hand, a yellows lens will distort the color, but sharpen your view.
To Polarize or Not to Polarize?
Sunglasses that are polarized will reduce the glare of the light which bounces off roads and water. People who drive a lot during the day or boat on the water often prefer polarized lenses. If you work or play near a lot of flat surfaces you may wish to investigate using polarized sunglasses.
Oversized sunglasses are all the rage among celebrities and the ultra hip crowd these days. But they aren’t for everybody. If you have a narrow face, they may make your face look even thinner. Don’t be afraid to stick with traditional sunglasses if you have a thin face or are looking for a more mature look.
