The 4 Most Important Things to Consider When Selecting Sunglasses

!±8± The 4 Most Important Things to Consider When Selecting Sunglasses

As an ophthalmologist, what are the 4 features most important features that I consider when selecting sunglasses? Sunglasses are an essential accessory, and we should all have a pair or two. You can get sunglasses nearly everywhere from the dollar store to Neiman Marcus, but what features really matter in protecting the health of your eyes?

1. 100% UV protection is the most important feature of any sunglass. Ideally, they should block both UVA and UVB as these rays certainly lead to many different eye diseases, including cataracts, macular degeneration, and pterygiums, just to name a few. Look for sunglasses labeled "UV 400," which blocks all light rays with wavelengths up to 400 nanometers, which covers all of UVA and UVB rays.

2. Polarized lenses reduce glare from surfaces like water, glass, and snow. They are superior to standard tinted sunglasses for driving, certain sports since they allow the wearer to see more clearly as the polarized lenses selectively block out glare instead of just making the environment dimmer.

3. Polycarbonate lenses are an ideal plastic for lenses, whether they are tinted or not. They are shatter resistant in that they are constructed from compressed plastic tubes. They are shatterproof as these tubes roll upon each other with impact instead of crumble like glass or traditional plastics. So, for the safest sunglasses, look for polycarbonate.

4. The fashion of sunglasses is certainly towards large frames, but I personally find light-weight glasses to be far more comfortable. Wearing a large heavy frame can even give some people a headache as the weight causes stress on the bridge of your nose, your ears, and or the temples. Wearing lightweight sunglasses reduces or eliminates this problem. Titanium is an excellent option for sunglass frames as they are lightweight, flexible and sturdy. They also have the feature of being non-corrosive and hypoallergenic, thus allowing it to have a longer usage life.

A Buyers Guide on Buying New Sunglasses

!±8± A Buyers Guide on Buying New Sunglasses

Many 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!

UV protection is the most important feature on a pair of sunglasses. UV rays, short for ultraviolet rays are dangerous for our eyes as they can damage our eyes. The most common result from UV rays is cataracts, which are not a pleasant experience. So always pay attention to the UV-stop performance on the sunglasses.

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.

The colors of the lenses are not only a fashion statement. Each color of the spectrum can offer something different. For natural color perception, lenses that are gray work best. Yellow lenses provide the most protection from blue light, while copper colored lenses provide the highest resolution.

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.

The comfort of sunglasses is extremely important, especially for athletes. Look for a light weight pair as this is crucial to making comfortable sunglasses. The ideal pair of sunglasses should feel like you're not wearing anything! A problem with many sports sunglasses is that they easily fall off, so be sure to check on this as well!

The last part of shopping for sunglasses is determining the type of lenses. Spherical de-centered lenses are known to provide an open optical field with the highest quality of clarity. They're also the most popular type of lens. Typically, they're also a lighter lens since they're made with a thinner material. Make sure to note the performance of blue light blocking from these lenses.

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!
