Tips On Buying New Sunglasses
Tuesday, July 27th, 2010Many people wear sunglasses, but most of those people don’t know what kind of sunglasses are actually the best. Anti-UV is a very important feature in sunglasses, but there are several key characteristics to also look for when purchasing sunglasses. If you’re looking for a quality pair of sunglasses, this guide will provide you with some of tips you should know!
Ultraviolet rays have proven to be dangerous on our eyes and can cause permanent damage. For this reason, UV protection is the most important feature in a pair of sunglasses. Besides permanent damage to our eyes, UV rays can also cause cataracts which are extremely unpleasant. The better the UV-stop performance, the more protection your eyes get from UV rays.
When shopping for sunglasses, many people ignore finding out if the glasses will distort images or now. In fact, many people don’t think of this at the time or don’t know that glasses can distort an image. I always recommend distortion free glasses as this option will not change an actual image. Sunglasses that are cheaply made may change the image and this can cause blind spots in the optical field. You may also experience some dizziness when you remove the glasses as your eyes need to adjust back to normal.
There are many colored lenses to choose from and each color offers a different perception. For the most natural perception, gray lenses are often used. Copper colored lenses are used for those looking for high resolution, while yellow lenses will provide the highest protection from blue light.
VLT which stands for volume of light transmission is another important feature to look for. The recommended range of VLT should be somewhere between 18% – 27%. This is a great range for wearing glasses on a sunny day. If you go above or below this range, the glasses can cause low visibility and on the other end, it won’t provide enough protection from solar radiation.
Everyone wants a pair of comfortable sunglasses. The lighter the weight of the glasses, the more comfortable they’ll feel. For athletes, comfort is crucial and it’s also very important you find glasses that don’t fall off either. The ideal pair of sunglasses should feel extremely natural, as if you’re not even wearing anything.
Choosing the right lenses, specifically their shape is crucial. The most popular type of lenses is the spherical decentered type of lens, which provides the best clarity. They’re made with thinner lenses, so they’re typically lighter weight too. While the shape is obviously important, take a look at the blue light blocking as well.
As discussed in this article, there’s more to sunglasses than looking good! Purchasing a quality pair of glasses will provide the protection that your eyes need. In addition, they’ll also provide comfort and can provide a great look too!
