How to determine if glasses protect against ultraviolet radiation? 0 8

You cannot do this unless you have specialized optical equipment used to measure the level of eye protection from ultraviolet radiation. Such devices are usually available in large optical stores, and there is typically no charge for the check.

As explained by one of the well-known optical shops, no type of labeling can guarantee high performance of sunglasses. Therefore, it is recommended to purchase glasses only from specialized stores, after requesting a certificate for the products of a specific brand.

Ineffective sunglasses block ultraviolet radiation poorly, which can lead to negative consequences for eye health. Additionally, low-quality tinted lenses are often cloudy, which reduces visual acuity at long distances.
