UV RAYS ASSAULT THE EYES 365 DAYS A YEAREveryone knows UV rays are extremely harmful on sunny days,yet they reach our eyes 365 days a year, even in cloudy weather.We get more than40% of UV exposure when we are notin full sunlight.

UV LIGHT IS A MAJOR HAZARD TO THE EYEUV light has a direct and cumulative impact on eye health,accelerating eye ageing and the appearance of cataracts.It is estimated that 20 million cataract surgeries areperformed every year.

Calculation based on urban workers in the Northern hemisphereIndoor low UV emission from fluo-compact lighting.

EXISTING 100% UV PROTECTION ONLY INTEGRATES UV CUT IN TRANSMISSION.

YET UV DANGER COMES FROM EVERYWHERE.

Essilor worked with independent 3rd-party(1)to develop a relevant protection index, based ona series of experimental measurements, taking into account UV light coming from all directions.

Like the SPF index quoted on skin care products, the Eye-Sun Protection Factoris a ratiobetween eye exposure with and without protection.

This global protection factor integrates:

- UV passing through the front surface of the lens and UV reflected by the back surface (a)- Corneal sensitivity to UV and solar spectral i rradiance(2)as UVA

and UVB do not represent the same danger for the eye - Different positions of the sun, as in real life (b) & (c)

- Representative frame and lens parameters(3)
