Over the last twenty years, there has been an active campaign on sun protection, and it’s not only about your skin, but also about your eyes.
As the ozone layer thins, the sun’s rays become more dangerous, so it is very important that you choose the right sunglasses when you buy them.
Although sunglasses have long been just a fashion accessory, people forget that their main function is to protect themselves from the sun. For this reason, most people buy glasses in non-verified places – from street vendors, Chinese, jewelers, just because some model is good for them and cheap.
This decision is devastating for vision, because poor quality glasses do not provide sufficient protection against UV rays, distort the field of vision and expose the eye muscles to great strain, which can permanently damage vision.
Children’s eyes are especially sharp on these glasses, and here are some of the features of quality sunglasses:
1. protection against ultraviolet radiation
UV rays are a harmful part of the solar spectrum and can cause many eye damages like cataracts, macular degeneration, melanoma (skin and eyes) or accelerate a degenerative process.
Safety glasses with good UV protection will effectively protect you from potentially dangerous sunrays.
2. quality glass
Not only do bad glasses not protect against UV rays, but they also have bad lenses. With good glasses in the original production, the optical part remains unique, for which there is a quality guarantee, which also entails a higher financial expenditure, but we all know that human health has no price.
3. they do not tire the eye
With good glasses, you will not get into the situation of feeling like you have dioptres and not feeling comfortable wearing glasses. Poor quality glasses have a number of optical defects, which means that the objects are in a different position than they actually are.
4. grasp the glasses that fit perfectly
A good spectacle frame is the most important point when choosing a pair of spectacles, besides the quality of the lenses. A quality frame that fits your face, doesn’t flake off and makes it easier to wear glasses, almost as if you didn’t have them at all. Glasses of poor quality have unstable, fragile and brittle frames that do not fit your face, as is the case with good workmanship.
5. not already damaged vision
The sunglasses you buy at a street counter are a particular danger to your eyes if you are nearsighted or farsighted. This is because your glasses slightly distort your visual perspective, which is why your dioptre can only grow. With quality glass, you will not have such worries.
After all, you should know that it is more dangerous to wear poor quality sunglasses than not to wear any at all. Without sunglasses, the eye is protected by the shrinking of the pupil, whereas when you look through inferior quality glasses, the pupils dilate and miss dangerous UV rays.
