25 E - S P F EYE-SUN PROTECTION FACTOR NEW CRIZAL FORTE UV. SO SAFE, SO CLEAR.
EVERYDAY PROTECTION IS ESSENTIAL UV LIGHT IS A MAJOR HAZARD TO THE EYE UV 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 are performed every year. UV RAYS ASSAULT THE EYES 365 DAYS A YEAR Everyone 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 than 40% of UV exposure when we are not in full sunlight. UV qty (Lx) 500 5 000 25 000 100 000 UV qty per year ~7% 5% 30% 58% 40% Calculation based on urban workers in the Northern hemisphere Indoor low UV emission from fluo-compact lighting.
ULTRA PROTECTION. AGAINST. ULTRAVIOLET. ON ALL CURRENT AR LENSES THE MAIN UV EXPOSURE COMES FROM THE BACK UV LIGHT UP TO 50% All clear lens materials cut between 95% (1) to 100% of UV rays passing through the front of the lens. All current AR lenses show high reflection of UV into the eyes. Measurements have found that UV reflected from back surface account for 10 to 50% (2) of total exposure. New Crizal Forte UV raises clear lens UV protection to a new level, also protecting against UV reflections off the back surface of the lens. (1) UV cut by transmission: 1.5 index cuts 95%UV, UHI indexes cuts 100% UV. (2) % of total UV exposure received by eye without any protection. Up to 50% depending on lenses and fitting parameters.

INTRODUCING E-SPF UV EXPOSURE BY REFLECTION UV EXPOSURE BY TRANSMISSION 25 E - S P F EYE-SUN PROTECTION FACTOR a UV captor located in the eye-ball of a dummy, measuring front and back UV exposure. A NEW INDEX MEASURING THE REAL UV PROTECTION GIVEN BY A LENS. 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 on a 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 Factor is a ratio between eye exposure with and without protection. This global protection factor integrates: b UV exposure measured at different positions of the sun. 12AM - UV passing through the front surface of the lens and UV reflected by the back surface (a) - Corneal sensitivity to UV and solar spectral irradiance (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) (1) E-SPF developed by Essilor, endorsed by Karl Citek, OD, PhD, FAAO, Professor of Optometry, first researcher to have published on the hazard linked to UV back surface reflection.
