Sunglasses: just an accessory or a filter protection from the sun?

The optically treated absorbent lenses of sunglasses filter out harmful infrared and ultraviolet radiation. Ultraviolet rays are the most harmful to the eyes.

In recent years, medical science has highlighted the role they play in accelerating corneal aging, the development of cataracts, and several retinal diseases. Sunglasses that do not have optically treated absorbent lenses block some of the light that reaches the eye, but do not block harmful ultraviolet radiation.

Thus their dark lens dilates the pupil and a large intensity of harmful ultraviolet radiation enters the eye.

That is why the right choice of sunglasses is very important. The color of the lenses should reflect with the greatest possible fidelity the natural colors, while protecting from the glare caused by the sun.

According to the European Regulation, sunglasses are divided into four categories depending on their degree of protection. The category of each glass should be written on it with the CE symbol and a pictogram. The absorbent sunglasses are made of different materials and with many additional treatments depending on your needs.
