Prescription sunglasses are more than just a fashionable accessory you can wear outdoors. If you plan on wearing them, they can be just as important as your normal glasses. Before buying your prescription sunglasses, it is important that you know what to look for.

UV Absorption

The main reason for wearing prescription sunglasses is that they help to protect your eyes from harmful ultraviolet rays. The level of UV absorption is just as important for glasses as it is for sunblock. The higher the absorption your sunglasses have, the more protection they offer your eyes. Sunglasses that are composed of polycarbonate lenses offer the best UV absorption.

Avoid sunglasses that contain triacetate. These glasses provide the least amount of absorption since it is primarily a thin film that coats the lenses and can leave your eyes vulnerable to the damage from the sun's rays. To ensure you get the highest level of protection, always purchase your glasses from a reputable optician. 

Color

Prescription sunglasses come in a wide range of colors that are designed to fit any style. For the most part, the color you choose is a personal selection. However, the color that you choose can have an impact on your eyes ability to detect differences in brightness and contrast.

If you are concerned with changes to your color perception, opt for a neutral density gray. Despite the gray tint on your glasses, your perception of colors will not be changed. The neutral gray color also helps to minimize any distortion that would usually result from wearing colored sunglasses. You do not have to be limited to one color. The sunglasses can be a blend of colors, such as blue and green.

Ultimately, you might have to try several colors before you find one that feels comfortable to you.

Polarized Lenses

If you plan to spend a lot of time on the water or driving, opting for prescription sunglasses with polarized lenses might be the best option. The lenses work by blocking light that is reflected from the road or water, which results in a reduction in glare. The lenses also have an added bonus. They usually have a high level of UV absorption.

To ensure that you get high quality prescription glasses, it is ideal to work with your optometrist to find a pair that is suited for you. For more information on getting some good eye protection, talk to a company like Wear Eyewear.
