Did you know? Did You Know_UV.mp4
UV Light: a major hazard to health (1) Myers M, Gurwood AS. Periocular malignancies and primary eye care. Optometry.2011;72(11):705-12. UV light has a cumulative impact over time causing : Eyes diseases Accelerated appearance of cataracts 20 millions of eye surgeries every year Skin aging (wrinkles) & diseases 90% of skin cancer occurs on the face and neck, with 5 to 10% occurring on the eyelids (1)
Eyeglass wearers want the clearest vision (1) … …which means the clearest lens but is it the safest ? For 98% of AR wearers, Clarity of Vision is a key factor.Source: (1) Ipsos International Survey - 1493 respondents – 7 countries – “most important characteristics when purchasing eyeglasses” – 2010. What wearers want…..
Transmission is the process of light passing through a lens All HMC lenses are designed to maximize transmission of visible light Transmission through the lens Reflection from back side of the lens Direct light coming from the sky Direct light coming from the side and from ground reflection Higher-index materials block 100% UV light transmission, as do Transitions® lenses “100% UVA/UVB” refers only to reduction in UV transmission through the lens The known danger: UV Transmission
UV Reflection: the unaddressed danger Independent tests show up to 50% of UV exposure comes from the back and sides to hit the rear lens’ surface A newly recognized medical hazard, which has previously gone unaddressed All existing HMC lenses show high level of reflection of UV into the eye Addressed by lens material High Index or Transitions® lenses Unaddressed medical hazard
Do we have any solution ?
SO SAFESO CLEAR NEW Introducing…
*For clear lenses with anti-reflective coating. Lenses performance only. Measures: K. Citek. Pacific University College of Optometry, USA. 2011. So safe, So clear UV BEST UV PROTECTION * + ReflectionsScratchesSmudgesDustWater BEST ENDURING CLARITY OF VISION
The most advanced AR lens, Now with exclusive backside UV protector BACKFRONT LENS SCRATCH-RESISTANCE DUST REPELLENCE SCRATCH-RESISTANCE AR EFFICIENCY SMUDGE & WATER REPELLENCE AR EFFICIENCY BROAD SPECTRUM TECHNOLOGY NEW A differentiated AR coating on front and back surfaces
ULTRA PROTECTION AGAINST ULTRAVIOLET THANKS TO BROAD SPECTRUM TECHNOLOGY Introducing Crizal Forte UV with Back surface UV protector
Crizal Forte UV : Ultra protection against ultraviolet Front UV Transmission cut by Material Back UV Reflection stopped by Crizal Forte UV + Result: Front & back UV minimized
UV Reflection % Crizal Forte UV: the best back surface UV protection on the market Back surface UV reflection Crizal Forte UVCompetitor A Premium AR Competitor B Premium AR Competitor C Premium AR UV exposure is 5 to 10 times lower than main AR competitors How do you easily translate this protection to your patients?
A new index developed by Essilor, endorsed by independent 3rd-party, certifying the global UV protection of a lens E-SPF Definition Introducing the “Eye- Sun Protection Factor” E-SPF endorsed by Dr. Karl Citek Protocol + Values Dr. Karl Citek, American Professor of Optometry, OD, PhD, FAAO*. One of the first researcher to have established the hazard linked to UV backside reflection.
E-SPF is endorsed by external experts Front: Transmission calculation (%Tuv) : An international standard ISO 8980-3 Back: Reflection calculation (%Ruv) : A method approved by independent R&D organism E-SPF calculation integrates exposure by the front & the back: E-SPF endorsed by Dr. Karl Citek Protocol + Values Dr. Karl Citek, American Professor of Optometry, OD, PhD, FAAO*. One of the first researcher to have established the hazard linked to UV backside reflection.
E-SPF Formula E-SPF = Exposure Without Lens Exposure With Lens = 100% T uv + R uv Back & sides UV exposure: % of rear surface reflection Front side UV exposure: % of Transmission through the lens E-SPF = 100% T uv = 0 % + R uv = 4% E-SPF for Crizal Forte UV Airwear = 25 Direct eye exposure depending on external factors (wearer's morphology, frame shape, position of wear....) is not integrated in the formula of E-SPF ESPF measures and protocol endorsed by Dr. K Citek, Pacific University College of Optometry, Oregon, USA, Rounded if needed to the best higher (3 / 5/ 10 / 25) to keep it simple and maintain similarity with cosmetics

Executive summary UV is harmful & Everywhere. UV reaches eye from Front & Back Up to 50% from back! CRIZAL FORTE UV Competition Clear (all Index) & Transitions (all Index) Crizal Forte UV 1.50 Clear Crizal Forte UV Clear – 1,56, 1.60, 1.67, 1.74, Airwear Transitions – 1.50, 1.60, 1.67, Airwear Because Crizal Forte UV has “back-side UV protector”. Front AR and Back AR is different. Reduce Back UV reflectance with special Crizal back AR Competitors 20 to 40% vs. Crizal Forte UV only 4%! UV Reflection % Back surface UV reflection Crizal Forte UV Competitor A Premium AR Competitor B Premium AR Competitor C Premium AR Thus Need UV Protection from front & back Front = block UV transmission Back = reduce UV reflectance Need measure of total UV protection for eye (Front & Back UV) eSPF grading = EYE SUN PROTECTION FACTOR
