Sunglasses are an important accessory for everyone, whether you wear prescription glasses or not. And while buying a set of shades might seem simple, there is a lot to consider if you want to get the most for your money. Here are the most frequently asked questions we hear from customers looking for that perfect pair of sunglasses.

Can children wear sunglasses?

Absolutely! In fact, children’s eyes are at an even higher risk than adults of being damaged by UV rays from the sun. Aside from hats and sunscreen, sunglasses should be a consistent part of every child’s life. Sunglasses have the added benefit of protecting the sensitive skin around the eyes, an area that is notoriously difficult to apply sunscreen to, especially with children.

Is there a difference between cheap and expensive sunglasses?

While you certainly don’t need to shell out hundreds of dollars for designer shades, there is a quality difference between dollar store sunglasses and the slightly more expensive brands. What makes sunglasses more expensive is polarized lenses and UV resistance. Polarized lenses are a nice glare-reducing feature that you can take or leave, but UV resistance is important. It is always worth a few extra dollars to get sunglasses that are 100 percent UV-resistant.

How can I tell if sunglasses are UV-resistant?

Look for sunglasses labeled as blocking “100 percent” of UV rays. Many inferior sunglasses will simply say “blocks UV” or nothing at all, and these lenses will not give you adequate protection. Wearing sunglasses that do not block UV rays can actually be harmful as the dark lenses encourage your pupils to dilate, thus letting in more UV light than they would otherwise.

What is UV resistance?

The same light rays that damage your skin can also damage your eyes. Sunglasses that boast UV resistance will block the sun’s most harmful rays from reaching your eyes or the skin around them. This protects you from skin sunburn (and eye sunburn!). It may also lower your odds of macular degeneration or cataracts later in life.

And UV protection doesn’t have to break the bank. All sunglasses from 39DollarGlasses come with 100% UV resistance and can be fitted with custom prescription lenses, all at great prices.

Can sunglasses fit over prescription glasses?

Some sunglasses are shaped to fit easily over prescription glasses. But the good news is you probably don’t need to bother. Sunglasses can be fitted with prescription lenses.

Which lens color should I get?

Lens color is entirely a personal preference, it has no bearing on the functionality of the sunglasses. Some colors enhance contrast better in certain situations. For example, yellow is a popular choice among winter athletes because it works well in the snow. Grey and brown are often chosen for everyday use because they cause very little color distortion and the environment appears almost normal.

Does tint affect UV resistance?

The tint of your sunglasses does not affect the level of UV protection. Choosing a darker or lighter tint is an aesthetic choice.

Can sunglasses be made with progressive lenses?

Yes! Sunglasses can be fitted with bifocals, trifocals and progressive lenses to help you see great while protecting your eyes.

Which is better: photochromic glasses or prescription sunglasses?

This is another matter of personal choice. Photochromic (commonly referred to as Transitions®) lenses darken depending on environmental light. Many people opt for photochromic lenses instead of a separate pair of prescription sunglasses if they go in and out of sunlight frequently. But for those who spend extended periods of time in the sunlight, separate sunglasses can be an easier option.

What are polarized sunglasses?

Polarized sunglasses block horizontal light to reduce glare. They are popular among outdoor enthusiasts as they make sports and water activities easier to manage. They can also be helpful when driving. Some pairs of specialized prescription eyeglasses are also designed for reducing glare while driving.

Do polarized sunglasses block UV rays?

Polarized sunglasses do not automatically protect the wearer from ultraviolet rays. Be sure to look for a “100 percent UV-resistant” label.

How many pairs of sunglasses do I need?

Most people get by with one decent pair of sunglasses, but your needs might vary. If you are an avid athlete, for example, you may buy multiple pairs with different tints. Some colors perform better under different weather conditions. Yellow-tinted sunglasses, for example, work well in snowy environments.

When should I wear sunglasses?

As often as you can. Even overcast days still send UV light into your eyes. Damage done to your eyes from UV rays is cumulative, so the more time you spend protected, the safer you’ll be. So remember, sunglasses are for every day, year-round! Go to to find the best deals on this year’s hottest shades.
