Sunglasses that only block visible light but cannot protect from UV rays are of no use; On the contrary, it increases the risk of cataracts by damaging the pupil.
The most important accessory of summer is undoubtedly sunglasses... Prof. from Yeditepe University Eye Diseases Research and Application Center. Dr. Ilgaz Yalvaç answered our questions about the use of sunglasses…
Does expensive glasses mean high quality?
A quality sunglasses must be 'UV light blocking'. Sunglasses without this feature only prevent too much light from passing through. However, this restriction does not provide any benefit; on the contrary, it causes harm. Because the pupil does not shrink when colored glass is worn. Thus, harmful ultraviolet rays enter the eye in large quantities. A quality sunglasses must be certified for quality and UV blocking.
Why should we not use cheap glasses?
Sunglasses that do not block UV light will cause plenty of harmful UV rays to enter the eyes. It can cause serious eye diseases.
IT MAY CAUSE CATARACT
What kind of damage can wrong sunglasses cause to our eyes?< br /> Sunglasses that do not have UV blocking properties but only have dark colored lenses increase the risk of cataracts and age-related macular degeneration.
Can glasses with mirrored or polarized lenses provide extra protection?
IT MUST BE UNBREAKABLE HARD PLASTIC
What should we pay attention to when choosing sunglasses for children?
The color of sunglasses lenses for children should not be too dark and UV protection should be sufficient. The type of glass should not be chosen from hard and easily breakable materials. The frame should be suitable for the structure of the face, and the nose and ears should be supported with silicone pads. Sunglasses should be used with a hat.
Is it better not to wear any than to wear fake sunglasses?
It is better not to wear any than to wear fake sunglasses. Sunglasses, which only block visible light but do not block UV rays, disable the eye's natural ability to protect itself. Since the pupil is wide open in the dark environment provided by sunglasses, a large amount of invisible UV rays enter through the open pupil. For this reason, fake sunglasses without a UV filter should not be used.
MISTAKES WE KNOW TRUE
-UV protection is not related to the darkness of the color of the glasses, but to the material they are made of. The tinting ratio only provides visual comfort by reducing the intensity of the light.
-Polarized glasses stop glare, but they do not protect against UV rays.
-Cleaning glasses with the corner of clothing and throwing them haphazardly in a bag or pocket are among the most common mistakes. These errors cause micro scratches on the glass. These invisible scratches deteriorate the quality of vision over time.
-When not in use, the glasses should be stored in their original box, and they should be cleaned with running water, soap or the microfiber cloth provided with the product.
-People who use contact lenses should use lenses with UV filters. They should wear sunglasses even if they do. -Sunglasses provide protection against the drying problem in the eyes that contact lens users often encounter.
-In environments where the sun is very intense, be sure to wear sunglasses with a shield. We must protect our eyes from the undesirable effects of sunlight with PKA support.
HOW DO WE RECOGNIZE QUALITY SUNGLASSES?
-Sunglasses must have a certificate stating that they block UV or ultraviolet rays.
-When you wear the glasses, you should not see the surroundings blurry and the details should not be lost.
-Quality sunglasses should have a reliable registration certificate.
-When buying glasses, pay attention to whether the lenses are painted or mica, and whether there are scratches, bubbles and curvatures on the glass. should be done.
-Another way to understand quality is to focus on a vertical line after wearing the glasses. In this case, when you move a pair of unprescription sunglasses, the image does not move. If there is any movement or breakage in this line when you move the glasses slightly up and down, left and right, it means that the glasses are not suitable. should be chosen appropriately. Glasses that do not fit properly on the face expose our eyes to harmful sun rays leaking from the sides.
-Thin-stemmed glasses should be preferred so that they do not block the field of vision while driving.
-Another important factor is the glass color and darkness. The color and darkness of the glass has no relation to the degree of UV blocking. According to European standards, the lens color used should not have a misleading effect on the perception of the colors of traffic signs and signals.
