If you have a favorite pair of sunglasses, you might have been using them for years. Do sunglasses that have been used for a long time still protect the eyes from ultraviolet (UV) rays?

Research has not directly answered whether UV protection deteriorates over time. The only definitive way is to test your sunglasses.

Sunglasses with recommended protection will filter out all UV rays. UV rays can damage the eye’s surface tissues, cornea, and lens. Over time, UV damage increases the risk of cataracts, macular degeneration, and other eye diseases, which can reduce vision.

A 2016 study from the University of São Paulo in Brazil examined whether the UV protection of sunglasses was adequately tested. Dr. Jeff Pettey, an assistant professor of ophthalmology at the Moran Center at the University of Utah and a spokesperson for the American Academy of Ophthalmology, said, “This is different from testing whether the UV protection in sunglasses fades over time.”

Researchers found that the testing by Brazilian manufacturers might underestimate the amount of UV exposure that eyewear undergo over time. It is unclear what these findings mean for U.S. sunglasses testing, UV radiation exposure in Brazil is higher than in the U.S.

While the study raises more questions than answers, Dr. Pettey says consumers should not panic or rush to replace their beloved shades. Currently, no one recommends retiring sunglasses based on usage time.

In recent years, UV-blocking technology has improved. Most modern sunglasses have UV protection embedded in the lenses rather than coated on the surface. If you are concerned about the age and safety of your sunglasses, you can get them tested at an eyewear store with a UV photometer.

If you are ready to buy a new pair of sunglasses, Dr. Pettey offers these tips for choosing the most protective ones:

Look for a label that says “100% protection against UVA and UVB” or “UV protection 400”.

Choose larger sunglasses frames that cover the eyes and surrounding skin.
sunglasses frames that wrap around the sides of the face provide maximum protection.

If you are looking for some fashionable sunglasses, the following three sunglasses styles can help you stand out. In terms of acetate color, you can choose bolder tortoiseshell acetate patterns.

1. Oversized Sunglasses
Oversized sunglasses are among the best choices for women’s eyewear, as they are fun, eye-catching, and serve as an invitation to conversation. Stylish and trendy, the oversized design makes a fashion statement, implying a superstar attitude.

Oversized sunglasses come in various shapes, not limited to a single specific style. Depending on your face shape, you can opt for square, round, oval, or any other suitable style. Most oversized frames are made of high-quality acetate eyewear, but round oversized metal eyewear are also popular.

Ideal face shapes for oversized sunglasses: Oval or plump faces. They also work for round faces as long as the oversized frame outline is the opposite—square or rectangular.

2. Browline Sunglasses
This retro-style eyewear, popular in past eras, is gaining increasing popularity and has become one of the best-selling women’s frames.

The bold browline suggests a sense of seriousness, making it a preferred choice for professional women working in a business environment. Black is usually the top color choice for these straight browline sunglasses, making them easy to match with outfits. The straight browline style is almost always made of high-quality acetate rather than metal. These sunglasses feature thick frames for durability and overall shock resistance, so you don’t have to worry about breaking them.

Best face shapes for this style: Oval and round faces with a large forehead that can support this frame.

3. Tortoise Shell Sunglasses
Tortoise shell sunglasses, also known as horn-rimmed or cat-eye eyewear, have consistently been bestsellers in women’s eyewear, and their popularity shows no signs of waning. The frames are produced in beautiful nuances of honey yellow and wood brown to complement your facial features and style. The tortoise shell acetate color scheme looks great with almost any frame shape—round, square, cat-eye, or oversized.

With the tortoise shell acetate pattern, you only need to consider the shape of the frame. Try choosing a shape opposite to your face shape, and you will shine. You can find more information about matching eyewear to face shapes in our guide.

If you are looking for fashionable sunglasses, the following three styles can help you stand out. For colors, bold tortoiseshell patterns are recommended.

Check the product labels
Pay attention to whether the sunglasses are marked with anti-ultraviolet and impact-resistant functions. Not all sunglasses can block ultraviolet rays. If a pair of sunglasses has the “anti-ultraviolet” function, there should be labels such as “100% UV protection” or “UV400” on the product label or the front of the sunglasses.

For sunglasses with “impact-resistant” function, there should be descriptions like “with impact resistance”, “passed FDA certification”, “compliant with the highest European and American standards” on the label or instruction manual. Meanwhile, these labels or instruction manuals should be kept properly, so that there is evidence to rely on in case of problems.

In particular, when fitting myopic sunglasses for myopic children, it is recommended to choose myopic sunglass lenses with impact resistance to prevent unnecessary accidents for lively and active children during sports.

Observe the lens quality
When putting the sunglasses in front of your eyes, look at distant objects through the lenses. Move the glasses up, down, left and right, and the target should not swing, and the lens color should be stable. Looking through the lenses, the colors of surrounding things should not be distorted, and the ability to distinguish different color signal lights should be maintained.

The depth of the sunglasses lens color is not very helpful for resisting ultraviolet rays. When choosing sunglasses, in addition to pursuing beauty and recognizing the labels, more attention should be paid to their protective effect. Good sunglasses can effectively block ultraviolet rays and glare, and reduce the damage to eyes from bright light, harmful ultraviolet (UV) light and glare. Polarized lenses, anti-reflective coated lenses, etc., can help sunglasses better reduce glare, prevent reflection, increase the contrast of objects in foggy and cloudy days, and make the vision clear.

Many fashion influences choose to wear cool sunglasses in the hot summer to enhance the fashion sense of their outfits. But many people may wonder: do I usually need a pair of sunglasses in summer? After all, I don’t need to strike a pose. Today, I will answer this question for you.

Is a pair of sunglasses really necessary? Normal eyes can adapt to light by themselves. The main reason for wearing tinted sunglasses is that the eyes feel uncomfortable, or that long-term exposure to strong sunlight at work may damage the eyes. “People’s ability to tolerate strong light varies. If you have to squint or often shed tears under the scorching sun, then you should wear sunglasses,” an ophthalmologist advised. Strong light is harmful to the eyes. A person who often stays in the scorching sun will have their night vision reduced by half. Therefore, if you are walking a long distance or staying on the beach, you should wear sunglasses.

However, unless you need to wear dark sunglasses as specified by an ophthalmologist due to pathological conditions, do not always wear dark sunglasses to look cool or cover up your eye diseases. A publication of the Hong Kong Consumer Council once warned that frequently wearing sunglasses unnecessarily can be addictive, and it will feel very uncomfortable to go without them during the day afterwards. Will cheap sunglasses damage the eyes?

The simplest answer is: quite possibly. Cheap tinted sunglasses are made by blowing rather than grinding. Blown sunglasses is bound to have various defects.

Substandard sunglasses are sold everywhere. Retailers say these defects are very minor and ordinary people will not notice them. This statement is specious. When the defects are minor, the eye muscles can more or less adapt. However, constant adaptation will eventually cause muscle and nerve fatigue. Of course, if you are just sunbathing and your eyes don’t need to work, the problem won’t be so serious. But if you have to work outdoors, such as in construction, reading, playing tennis, or driving long distances under the scorching sun, your eyes will keep moving up and down, left and right, from near to far, and you will use the entire range of the lenses. In such cases, it will be difficult to constantly adapt to a pair of lenses with poor quality.

In the hot summer, many girls choose a pair of sunglasses. They can not only block the excessively dazzling sun but also add a touch of style to your fashion look. Today, I’ll take you through how to pick the right sunglasses according to your face shape.

Inverted Triangle Face, Diamond Face: Recommend Soft Floral Frames

Although this face shape may look a bit like a superstar’s, in daily life, it tends to give a sense of distance. This is because the chin appears sharper than other face shapes. Therefore, when choosing sunglasses, try not to pick those with overly hard lines; otherwise, the strong linear feel will make your face look even more distant. You can also choose sunglasses with floral decorations to soften the lines of your face. Moreover, the shape of the eyewear frame can be a perfect circle that is wider at the top and narrower at the bottom, which can greatly reduce the sharpness of your chin.

Triangle Face: Wear Light-Colored Frames

The triangle face shape is quite similar to the square face in our perception. Both have distinct contours in the cheek area, and the forehead appears less wide, narrower than average, and the face shape is also shorter.

Girls with this face shape can choose sunglasses with a gradient color scheme from top to bottom. It’s best to pick ones where the upper part of the eyewear frame is one color, and the lower part is visually lighter. Wearing such sunglasses can not only modify your facial lines but also elongate your face shape. However, for triangle faces, avoid choosing frames that are too dark or overly fancy, as they will make your facial lines more prominent.

Round Face: Cat-Eye with Upward Curve is Suitable

Girls with a round face shape have more flesh on their faces, a relatively short chin, and the face is also on the shorter side, giving a cute look. This face shape is most suitable for cat-eye sunglasses.

Because wearing cat-eye sunglasses creates an illusion that the lines on your face are lifting upward. Besides cat-eye sunglasses, you can also choose ones with slightly higher temples. These types can well modify your face shape.

Pear-Shaped Face: Choose Wide Gradient Eyewear Frames

The most prominent features of a pear-shaped face are that the cheekbone area is relatively narrow, the temples look a bit sunken, there is a lot of flesh on the cheeks, but the cheekbones are high, so usually, the flesh on the face is not obvious. Therefore, when choosing sunglasses, it’s best to pick those with wide eyewear frames and wide temples, in gradient colors. Such sunglasses can modify the curves of your face, and this style can just cover the sunken temples, making your face look like a standard oval face.

Square Face: Match with Eyewear Frames That Are Not Too Narrow or Thin, with Arc Angles

For square faces, it’s advisable not to choose overly round sunglasses, as this will make your facial features more angular. However, don’t choose too wide or too square ones either, as they will highlight the flaws in your facial lines. It’s best to choose large sunglasses with slightly arc angles. Wearing such sunglasses has a good face-slimming effect, and they can also elongate your face shape, making your facial lines look much softer.

Oval Face: Match with Oval Eyewear Frames

The oval face is versatile and can go well with any shape of sunglasses. So you can confidently choose the most popular and trendy styles to match. But if you want to show off the advantages of your standard oval face, you can choose oval eyewear frames, which will better highlight the beauty of the facial lines of your oval face.

Sunglasses are definitely a fashion favorite and a great tool for styling in the shinny summer. But how do we choose the right sunglasses? Do we really need them? How important is the color of the lenses? What about the size of the lenses and eyewear frame? There’s actually a lot to learn about this.

Choosing Lenses
How to pick good lenses? Sunglasses are categorized into light-absorbing, polarized, coated, and photochromic types. The best lenses are polished using optical procedures, just like the optical frame prescribed by doctors. Plastic lenses, similar to Rx ones, vary greatly in quality. Generally, plastic lenses are lighter, shatterproof, and cheaper; however, they are prone to scratches, so special care must be taken when touching or cleaning them.

There are several simple ways to test the lenses: Observe them under light. The lenses should be completely clear, with no cross scratches, streaks, circles, bubbles, or stains at all. Move the lenses up, down, left, and right to look at objects with distinct lines, such as window frames or door frames. If these objects appear wobbly or distorted, the lenses have distortions and are not usable. To check if the lens color is uniform, pay attention to whether the two lenses have the same color and if their gradually lightening parts are in the same positions.

Lens Colors
The price of sunglasses doesn’t entirely reflect their optical quality. Because the most expensive ones may just have novel designs, and what you’re paying for could be the fashionable eyewear frame rather than the optical quality of the lenses.

What color is the best? Generally, natural pure gray and “smoke” colors are the best. Lenses of these colors are the hardest to manufacture, so inferior sunglasses won’t use them. Next is green. Blue and red lenses are only used in certain industrial applications. There are also special yellow lenses. Therefore, the choice of lens color depends on the purpose. How dark should the color be? The darkest colors are suitable for use in strong light. It’s very dangerous to use them when driving on roads with fluctuating light conditions. Many people find the lenses of the sunglasses they buy suitable in brightly lit stores, but they turn out to be too light when used at the beach or in the countryside. The best way is to take the sunglasses outside and look at the sun. It’s advisable that only 20% to 30% of the light can pass through in strong sunlight.

There is a rather special eyewear product called a “sunglass clip-on”. It is a type of sunglasses specifically designed for people who wear optical frame. By simply clipping this clip-on onto their existing optical frame, their myopia eyewear can instantly be transformed into sunglasses, thereby providing better protection for their eyes.

How should we choose a sunglass clip-on?
First, check if the sunglasses clip-on has a polarizing effect.

The polarizing effect can help us better distinguish objects under reflected light and strong light, making it suitable for people who fish, ski, or drive. In general, most sunglasses clip-ons have this function. However, regular eyewear brands will come with a polarizing test card, which features patterns of fish and water surfaces for consumers. Therefore, you can try on the sunglasses clip-on, and if you can see the fish, it indicates that its polarizing effect is good.

Second, verify if it has UV protection.

When purchasing a sunglasses clip-on, consumers must confirm whether the product has UV protection. If it only has a light-filtering function but no UV protection, it cannot fully block UV radiation, and the damage to the eyes cannot be avoided.

Third, inspect the structure of the sunglasses clip-on.

Non-regular brands usually use iron components, which can easily cause the lenses to get scratched and even harm the eyes. On the contrary, if we choose big brands, their quality is guaranteed. When the lenses come into contact and bear force, they can avoid the phenomenon of being separated by silicon gel.
