UV protection for sunglasses
The eyes, like the skin, are very sensitive to exposure to UV rays. We basically differentiate between UVA, UVB and UVC rays. The rays are invisible to us and have a wavelength of up to 400nm. They can cause acute damage to the retina. That is why it is important to perfectly protect the eyes both in leisure time and during sports. When buying new sunglasses, you should make sure that the sunglasses have 100% UV400 protection.
Buying sunglasses online: What should I consider?
Not only UV protection is important when buying sunglasses. The fit is also an important factor for the purchase. Good sunglasses should not only look good, they should also sit comfortably for several hours at the lake or on the roof top bar. If you are looking for sports sunglasses for both leisure and outdoor activities, rubberized temples are also an important feature. You can recognize high-quality sunglasses by whether they have a CE mark. The marking indicates that the product meets the necessary standards.

When are polarized sunglasses useful?
If you are looking for sunglasses on the internet, sooner or later you will come across the term polarized sunglasses. What does that actually mean? The polarizing filter in sunglasses helps minimize glare from reflective surfaces such as water or ice. Another advantage of polarized glasses is that the perception of contrasts becomes clearer. But beware of displays and screens: A disadvantage of polarized sunglasses is that it is more difficult to read dashboards in the car, wristwatches or even smartphones.
