How to Tell If Sunglasses Are Good Quality

Share and spread Love

Sunglasses are more than just accessories; they protect your eyes from the harmful UV rays that can cause eye damage. There are a few things you should look for when buying sunglasses to ensure they are of good quality.

One easy way to test polarized lenses is to look at something reflective, such as water or a road. The light should increase in intensity if the sunglasses are polarized.


If you’re going to spend a lot of money on stylish sunglasses, it’s important to buy high-quality ones. A few simple tests can help you determine if your sunglasses are worth the price.

UV protection is one of the most important things to look for in sunglasses. UV rays can damage your eyes, so it’s important to shield them as much as possible. You can test the sunglasses’ UV protection by shining a bright light on them. If the lenses glow, they do not protect your eyes from UV rays.

Another way to test your sunglasses’ UV protection is by looking for the ANSI label. This label shows that the sunglasses filter out 99% of harmful UV rays. You can also check for UV protection on the lens by holding them up to white paper. If the paper shines through the lenses, they don’t block UV rays.

It’s also important to choose a pair of good quality sunglasses with lenses that are made from a durable material. The lenses should be clear and free of distortion, which will ensure that your vision is protected.

You should also make sure the lenses are polarized. This specialized lens coating helps eliminate glare from horizontal surfaces, such as water, sand, roads, and snow. It will keep your eyes comfortable and prevent glare fatigue.

Sunglasses with polarized lenses are typically more expensive than regular sunglasses. However, if you wear them regularly, it’s well worth the investment.

Another factor that can affect the price of sunglasses is their frame material. You can find a variety of frames made from different materials, including plastic, metal, and acetate. Plastic frames are the most common because they’re more lightweight and affordable than other types of frames. Metal frames tend to be more expensive, but they’re also more durable than plastic ones.

While the frame’s material doesn’t contribute to UV protection, it can affect how the sunglasses fit your face. You’ll want to find a frame that fits snugly around your face. If the frames are loose, they can fall off or damage your face.

The frame material can tell you a lot about the quality of sunglasses. Cheap frames made from metal or plastic can be prone to rust, breakage, and other problems. High-quality frames, on the other hand, are crafted from stronger materials that will keep your glasses in good shape for longer. Look for a sturdy frame that fits comfortably on your face without pinching or squeezing your nose. The arms and hinges should also be flexible enough to move with facial movement.

Another way to tell if sunglasses are high-quality is by looking at their label. Most reputable brands will clearly indicate their UV protection on the labels of their products. For example, you may see ‘UV 400’ or ‘100% UV Protection’ on the label. These are signs of high-quality sunglasses that will protect your eyes from the damaging effects of the sun’s rays.

If you’re buying a pair of polarized sunglasses, make sure they actually are polarized. Many low-quality pairs of sunglasses market themselves as polarized when they’re not. You can test this by finding a reflective surface such as water or a glass table and looking at it through your sunglasses lenses. If the glare seems to increase as you tilt your head, your sunglasses are polarized.

Sunglasses are designed to protect your eyes from UV rays, reduce eye strain in bright conditions, and protect you from flying debris and other hazards. They can be expensive, so it’s important to choose a stylish and high-quality pair.

One of the biggest factors that determine the quality of sunglasses is the frames’ durability. A high-quality pair of sunglasses should be able to withstand frequent use, and the hinges and arms should be flexible enough to avoid breakage. The quality of a pair of sunglasses can be determined by examining the hinges and arms, the lenses, and the frame material. High-quality sunglasses are made with better materials and are built to last, so they’re worth the investment. The tips above should help you find the perfect pair of sunglasses for your next outdoor adventure.


Sunglasses are a style and fashion statement, but they protect your eyes from harmful UV rays. Sunglasses with a high-quality frame and lenses can make you feel confident and look great! However, knowing if you’re getting the right pair can be hard. It’s important to take the time to test and evaluate a pair of sunglasses, so you can be sure they are worth your money!

One of the most important things to look for in a pair of sunglasses is their fit. The frames should sit comfortably on your ears and nose without pinching or rubbing. The hinges should be sturdy and durable but still flexible enough to allow you to adjust them. Finally, the nose pads should be soft and comfortable against your nose.

The frame size is another important factor to consider. If the frame is too small, it will not provide the full protection you need. It is also essential to choose the right lens size. A large lens will cover more of your face, while a small lens will leave gaps between the frame and your skin.

Another thing to look for is whether the lenses are polarized. Polarized lenses are designed to reduce glare from horizontal surfaces such as water, roads, or snow. They work by reflecting light off horizontal surfaces and eliminating the blinding glare that can cause eye strain and headaches.

You should also check the label on the sunglasses to see if they offer UV protection. All high-quality sunglasses should have UV protection, which is usually indicated by a UV absorption logo or the phrase “UV 400,” which means they block all UVA and UVB rays up to 400-nanometer wavelengths.

If you want to be extra sure that your sunglasses are high-quality, you can try the UV flashlight test. Shine a UV flashlight against paper money to test for UV absorption. If the paper money glows, you should avoid purchasing these sunglasses. You should purchase a different pair if the paper money does not glow. You can also buy UV-blocking sunglasses that have been coated with a layer of transparent polycarbonate on the inside of the lenses. This coating is not as effective as a polarized lens, but it will help to protect your eyes from harmful UV rays.


Sunglasses should protect your eyes from UV rays, reduce eye strain and shield you from flying debris and other hazards. However, sunglasses are not all created equal. A good pair of sunglasses will have quality lenses and frames that provide durability for any adventure or sports activity you can throw at them. In addition to UV protection, other important attributes to look for include polarization, lens color, frame curvature, and comfort.

To test your sunglasses’ lenses, shine a bright light on them. If the light is distorted or goes dark, this means they have a coating that blocks harmful UV rays. This is essential for protecting your eyes from the effects of UV radiation, which can lead to cataracts and retinal damage.

The type of material used in the lens can also tell you a lot about their quality. Glass offers some of the best optical clarity available but is heavy and will “spider” when impacted (but won’t shatter). Polyurethane is a synthetic material that provides superior impact resistance and is very flexible and lightweight. Acrylic is an inexpensive alternative to polyurethane but can be scratched easily and may have image distortion.

Many people assume that more expensive sunglasses are better quality, but this is not always the case. For example, expensive designer sunglasses often have the same UV protection and polarization as less-expensive brands. In some cases, the difference in price is due to the additional features that are added to the sunglasses, such as hydrophobic and oleophobic coatings. These are a great touch for sunglasses that will see a lot of use, as they help to repel water and oils from your face, hair, and eyebrows.

Another way to test a pair of sunglasses is to hold them up to the light and observe the light reflecting off them. If the light is distorted or turns a different color, this indicates that the lenses are not polarized. This will cause glare on horizontal surfaces such as water, snow, or roads and can be distracting and uncomfortable.

One of the quickest and easiest ways to test your sunglasses for polarization is to use a UV flashlight at home. Simply hold a paper dollar up to the light, and if the bill’s watermark disappears through the sunglasses, they are likely polarized. If you want to take it a step further, you can purchase polarization test cards for just a few dollars that will quickly and easily tell you if your sunglasses are truly polarized.
