By choosing wrongly your glasses, you do worse than well
Pay attention to counterfeits. The material used can let UV, even if the glasses are tinted. Tinted lenses that do not filter out UV rays do not protect your eyes at all. On the contrary ! When there is sun, the pupil is more dilated than in daylight because of the darkening caused by tinted glasses. The UV rays then reach the retina directly. Therefore, it is worse for you to wear bad glasses than not to wear them at all in a sunny environment. To ensure the quality of your glasses, it is best to go to an optician.
Choosing the best protection against UV rays
The UV standard of the European Community divides the sunglasses into 5 categories, ranging from classes 0 to 4 according to the percentage of filtered rays (class 4 taking the ski goggles for intense solar brightness, with more than 90% of filtration ).
Make sure the class and color intensity of your lenses are appropriate for the level of sunshine, your activity, and the environment. For example, Class 4 lenses leave less light and are therefore more dangerous for driving. Also think that the glasses can be adapted to certain conditions, for example the sunglasses for the ski.
If it is registered UV-400 on the glasses, you make sure that your sunglasses will hide the harmful rays. Indeed, the UV400 protection ensures that 100% of ultraviolet rays are filtered (UVA, UVB and UVC). On the other hand, sunglasses with CE marking guarantee compliance with European regulations.
Warning ! If you wear lenses, wearing sunglasses is still necessary to protect the eyes.
