Sunglasses for boat : how to choose them ?

The risks of sun exposure

Wearing sunglasses is necessary, for adults, but even more so for children.

According to Marielle Gaumond, an optometrist specializing in eye diseases: " The impact of the sun's rays can be harmful over the long term and cause irreparable vision problems. Prolonged exposure without sun protection can lead to age-related macular degeneration.

UVA and UVB rays are harmful. Invisible to the naked eye, our eyes are very sensitive to them, which is why wearing sunglasses is important. The cornea and the crystalline lens serve as a shield to protect the eyes, but the rays can reach the retina and generate ocular pathologies, a cataract or an inflammation of the cornea. "
