In the sun, we usually take care to protect our skin and our family’s from UV rays. But we are often careless with our eyes which are especially vulnerable. Various solutions exist to effectively protect against UV rays, bright light and reflections that make outdoor vision difficult. Color, the level of protection for our eyes: the choice of lenses with or without correction depends on our sensitivity. But for some activities such as sailing, skiing or high altitude trekking, the level of protection needs to be stronger.

The E-SPF® index (Eye-Sun Protection Factor) was created to guide us in choosing lenses. The higher the value, the better the lens protects us against UV. For clear lenses worn daily, there are E-SPF® 10, 15, 25 or 35. For sun lenses, the E-SPF® index can reach a maximum of 50+.
