It is an important accessory for individuals who care about their style, as well as being important for the protection of health, with its visuality.

Therefore, it is possible to find many types and quality sunglasses in the market. While the visual aspect of using glasses is more important for most people, it is sometimes forgotten that the health aspect should also be taken into consideration and that products that are not suitable for health can harm the eyes. For this reason, it is useful to be conscious about the issues that need to be taken into consideration when choosing sunglasses. Although many people are confused when choosing, another issue that should be taken into consideration as much as the compatibility of the glasses with the face is the technical features of the glasses. For those who ask what to consider when choosing sunglasses, you can find what you need to know before choosing glasses from the rest of the article.

UV (Ultraviolet) Protection

Answering the question of what to consider when choosing sunglasses should definitely start with ultraviolet protection. Because the most important feature to consider in sunglasses is the level of protection of sunglasses against UV rays. In general terms, it can be said that each eyeglass lens blocks ultraviolet rays to a certain extent. However, healthy glasses should filter both UVA rays and UVB rays and protect the eye from 99-100% of all UV rays. Sunglasses must have a certificate for UV protection. These certificates are usually in the form of labels expressing the blocking power in nanometers, such as UV200, UV400, UV600. In summary, to answer the question of what should be considered when choosing sunglasses, your glasses must have the power to block at least 400 nm UV rays and be certified in this regard.

CE (Conformité Européenne) Certificate

For those wondering what to consider when choosing sunglasses, another issue to consider when choosing is the CE certificate of the product. CE certification, which is a quality criterion in general, shows that a product has been evaluated and found suitable according to European Union standards in terms of meeting safety, health and environmental protection requirements. For this reason, quality glasses according to European Union standards have the phrase ce conformité européene on them. If you are wondering what to consider when choosing sunglasses, you should add this document to your criteria. It is a good idea to check whether the sunglasses you will buy have this phrase, which means a reliable registration certificate, and to only buy CE certified products.

Quality of Sunglasses Lens

Another topic that should be included in the list of things to consider when choosing sunglasses, along with UV protection, is the quality of the glasses. Polarized glasses reduce glare reflected from surfaces such as roads, windows, puddles or snow, making the glasses more comfortable for the eyes. Likewise, glasses with mirrored coatings can protect your eyes by reducing the amount of light coming into the eye, especially in bright sunlight. In addition, for quality and long-lasting sunglasses, the lenses must be resistant to scratches and impacts. For this reason, it is useful to investigate the durability tests or techniques used regarding the durability of glass.

Glasses Should Focus on a Vertical Line

As a different answer to the question of what should be considered when choosing sunglasses, it can be said that you should do a vertical line focusing test. To do this, you can follow these steps:

  • Take the glasses in your hand and hold them in front of you at arm's length and look at a straight line through them.
  • Then, look at a tree trunk, door edge or a column. Focus on a vertical line such as and move the glasses slowly, up and down, left and right.
  • Gently move the lens along the line you targeted and examine the image.

After following these steps. Then, at the last stage, when you look carefully, you should check whether there is any difference on the flat edge. If the image is distorted, shaken, shaken or breaks while following this straight edge, those glasses are not suitable. Because in this case, there are probably some distortions in the smoothness of the glass or in the fineness-thickness balance, which indicates that the glass is not of sufficient quality.

Lens and Frame Material

While continuing to answer the question of what should be considered when choosing sunglasses, it is also necessary to mention the lens and frame materials. The lens in sunglasses may be made of various materials such as glass, plastic and polycarbonate. If you prefer a product that is scratch or break resistant, especially if you are looking for sunglasses for your child, you can choose polycarbonate lenses.

If you need a prescription lens, first consult your ophthalmologist

You should visit and find out your current eye number. Then, together with your optician, you can choose the lens that best suits you. Another answer to the question of what should be considered when choosing sunglasses is that the frame material is suitable for the purpose. In this regard, your aesthetic preferences will come to the fore. If you choose unbreakable, bendable and flexible frames, it may provide an advantage in terms of durability. Likewise, choosing a frame that is not too heavy may be advantageous in terms of ease of use.

Light Absorption Rate Compatibility

Another way to buy good sunglasses is to choose them by checking how much of the outside light the lens absorbs, how much it reflects, and how much it lets in. For this reason, light absorption rate should be among the criteria for those wondering what to consider when choosing sunglasses. Information about the light absorption rate is usually included in the documents that accompany the sunglasses and contain product information. Healthy and high-quality sunglasses are required to screen 75-90% of visible light (1). The absorption rate may be lower for sunglasses that will be used in environments where there is not much glare and the sun's rays do not come at angles close to vertical.

The absorption rate determines how much of the light coming from the eyeglass lens absorbs, reflects and lets in. In this respect, a ratio of 40-50 may be sufficient in city streets where there is not much light on the eyes. On high hills where the sun shines directly, you may need absorption rates of 50-70 at the seaside and 80-85 when skiing. At this point, you can add the mirror test to your list of what to consider when choosing sunglasses. To test the suitability of a pair of glasses in terms of light absorption rate, you can look at yourself in the mirror after wearing the glasses. If you can see your eyes very easily through the mirror, the lens of the glasses is probably too open and the light absorption rate is lower than the target.

Choosing Glasses According to Face Shape

Compatibility with your face shape may be another important answer to the question of what to consider when choosing sunglasses. Having sunglasses suitable for your face shape makes it easier for you to achieve an aesthetically pleasing look, while also preventing unwanted unfiltered light coming into your eyes from the edges of the glasses. UV rays, which are the most important enemies of eye health, and the bright light that hits the eye intensely because it does not pass through the filter, should not reach your eyes around the glasses lens. Wrapping your sunglasses around your temples may be a healthier alternative as it will prevent light from entering your eyes from the sides. Additionally, there are different frame shapes produced to suit different face shapes such as oval, round, square and triangle. If you are wondering what to consider when choosing sunglasses, you can also take these into consideration when choosing.

One Should Not Focus on Fake Brands

Another confusing issue for those wondering what to consider when choosing sunglasses is the brand. Although sunglasses are a protective health equipment, they are considered only as a style accessory for most individuals. For this reason, the demand for fake sunglasses produced as replicas of expensive eyeglass brands is unfortunately very high. Fake glasses only replicate quality glasses in terms of appearance, but it is generally not possible to replace these products in terms of health features and quality factors. Sunglasses that do not have UV blocking features, have light absorption outside the standards, and have very dark colored lenses are likely to harm your eyes rather than benefit them. These glasses do not provide any health protection, and since they block excessive light, the pupil expands and opens to see better. In such a case, the eyes become much more vulnerable to harmful UV rays. One answer to the question of what to consider when choosing sunglasses is to definitely avoid the use of fake sunglasses. In case of budget constraint, products of companies that are more affordable but produce healthy and high-quality eyeglass lenses can be preferred.

Which Color Sunglasses Should Be Used When?

For those who wonder what to consider when choosing sunglasses, one of the issues that creates indecision when buying glasses and therefore is frequently wondered about is the color of the lens. In the production of sunglasses, it is necessary to filter UV rays and use special coatings to block these rays. Since these coatings are transparent, the color of the glass is not an indicator of protection against ultraviolet rays. However, the color of the glass is one of the factors that affects how much of the light coming from the outside is absorbed. In response to the question of what should be considered when choosing sunglasses, it can be said that the following should be taken into consideration in terms of lens color:

  • Mirror coatings reduce the amount of light coming into the eye and provide advantages in areas such as the seaside and ski slopes. However, it may create a dark image in a city environment where there is not much sunlight.
  • Brown, grey, green or yellow sunglass lenses can be preferred to minimize color distortion that causes colors to appear different from their natural tones.
  • >
  • Gray colored glasses can reduce the brightness of the incoming light without causing any difference in the perception of colors, while amber-yellow colored glasses can help you achieve the best vision in environments with lower light intensity.
  • When choosing the color of the eyeglass lens, your eyesight can be reduced. Color may also need to be evaluated. For example, since people with blue eyes are more sensitive to light, they may be more comfortable with gray lenses that block more visible light. People with brown eyes may prefer brown lenses to avoid having to take off their glasses frequently. For this reason, it would be beneficial to consult an ophthalmologist when making your choice.

If you are thinking of buying sunglasses and are looking for an answer to the question of what should be considered when choosing sunglasses, you can pay attention to the quality features above before choosing your glasses. Your doctor may give you different answers to the question of what to consider when choosing sunglasses. Since you may have individual differences depending on the condition of your eye health, it will be beneficial for you to first undergo an examination by your ophthalmologist and make your choice in line with your doctor's recommendations when choosing your sunglasses.
