Sunglasses and UV rays

WHAT ARE UV RAYS AND WHAT ARE THEIR EFFECTS ON THE EYES?

Ultraviolet rays are components of sunlight. Depending on their wavelength, they are divided into UVA, UVB and UVC.

UV rays can cause inflammation of the conjunctiva and cornea. Over time, these dangerous rays from the sun can cause the lens of the eye to become cloudy and damage retinal cells. Studies show that UV rays are harmful to people with healthy eyes. Children’s eyes are particularly sensitive, as are the eyes of people who have undergone cataract surgery.

HOW TO PROTECT YOUR EYES FROM HARMFUL UV RAYS?

Sunglasses are the main way to protect your eyes from harmful UV rays. It is very important that sunglasses are of good quality, i.e. have a UV filter. For this reason, sunglasses should be bought from optical shops where the sunglasses have been tested and comply with European Union requirements.

ARE SUNGLASSES ONLY NEEDED IN SUMMER?

Although sunglasses are an integral part of the summer look, they should not only be worn in the summer, but also in other seasons, especially in the winter, when the damage from UV rays is even greater as snow and ice reflect 95% of light.

Sunglasses should also be worn in the mountains or at the seaside, as snow and water reflect sunlight, making the sun’s rays more intense and damaging.

WHAT TO LOOK FOR WHEN CHOOSING SUNGLASSES?

Look for the UV-400 or CE marking on sunglasses. These markings mean that the glasses protect our eyes from UV rays with wavelengths up to 400 nanometres. This gives you 100% protection against harmful UV rays.
