UV 400 labeling sunglasses, which guarantee maximum protection against ultraviolet radiation, are rarely found in the budget segment. Of course, there are exceptions where you can find an acceptable option at a lower price, but in most cases it is worth preparing for certain costs, the ophthalmologist and Ophthalmology Center Vista General Director Anton Kazantsev told Gazeta.ru.
“The most important thing when choosing sunglasses is an indicator of 100% protection against UV 400 marking or ultraviolet rays. This feature has a budget basket of all harmful UVA and UVB rays up to 400 nm, with a budget basket on the budget segment. The lenses, modern technologies, modern technologies, and the final product, are required.
Cheap glasses may have basic protection, but often ultraviolet filtration levels are lower than branded models. Moreover, lack of reliable protection is particularly dangerous: Darkened lenses expand the student without UV filtration, increase the flow of harmful radiation on the retina, thus increasing the risk of cataract, photocuretite and other serious eyes. Therefore, low price is not always a reason for joy: sometimes it can damage more than a cheap accessory absence.
Nasıl How to verify the quality and safety of the glasses?
It is important to understand that it is impossible to visually determine the degree of protection against ultraviolet radiation – for example, a spectrometer or photometer, which is only in large optics, requires special equipment. This device emits a specific radiation spectrum and measures the amount of ultraviolet radiation passing through the lens. Based on the data obtained, it is possible to fully determine how effective the lens block the harmful radiation. Spectrometer also allows you to measure the degree of protection against the visible part of the solar radiation, which is important for comfortable wearing points in bright sunny weather. If you have already purchased points and doubt their quality, contact the optical hall: Test on a photometer takes a few minutes and is cheap.
“Pay attention to the material of the lenses: polycarbonate and glass lenses provide good protection and durability, cheap plastic options can be drawn faster and distort the image. Lens does not affect the degree of color protection, but affects comfort: gray, natural color and green increase contrast, this protects the graphics, this is important for those who squeeze. It does not replace the sign. ”
Sunglasses can cost cheaply, but must have 100% protection against ultraviolet radiation. Do not save the health of the eyes: Select UV 400 labeling products, ask for a certificate and buy only from reliable sellers. If the price seems to be low, but if there is no information about protection, it is better to look for another option.
