UV rays: everywhere, all the time!
5% of the UV rays that reach the skin are UVB, present mainly in the summer and mid-day, and 95% are UVA (20% UVA said short and 75% said long).
UVA levels are constant throughout the year, whether weather is good or the weather is over: whether or not there is sun, your eyes and skin are exposed to harmful UV rays .
Your eyes and your skin are particularly sensitive to UV. Their long-term effects on your health can be considerable.
It is therefore essential to protect them on a daily basis.
Check UV protection ratings
> For the skin
Sun Protection Factor (SPF): This is a laboratory index that measures the effectiveness of sunscreens and skincare products. It informs us about the ability of a product to protect us from sunburn: the higher the SPF, the better it protects us from UVB rays.
PPD (Persistent Pigment Darkening): it measures the protection factor against UVA responsible for premature aging of the skin. Choose sun creams on which UVA is indicated in a circle: they will protect you best.
> For the eyes
The E-SPF (Eye-Sun Protection Factor) is a new international index that guarantees that your glasses provide the best UV protection possible.
E-SPF * certifies the overall UV protection of a glass (UVA and UVB), whether it's the clear glasses you wear on a daily basis or the solar lenses that are prescribed for you.
Inspired by skin care standards, E-SPF works on the same principle: the higher it is, the better you are protected against UV.
Yet not all glasses offer the same UV protection. Ask your eye care professional for glasses that best protect your eyes from the sun.
* Only applies to glasses. Measures taken by an independent organization - United States - 2011.
