Crizal Forte UV
CRIZAL FORTE UV. SO SAFE, SO CLEAR.
The most advanced Crizal antireflective lens, providing ultraprotection against Ultraviolet and perfect clarity of vision
I. Ultra Protection against Ultraviolet
II. Perfect Clarity of Vision
CRIZAL FORTE UV. SO SAFE, SO CLEAR.
The most advanced Crizal antireflective lens, providing ultraprotection against Ultraviolet and perfect clarity of vision
The Process
A new intermediate SR booster layer (Scratch Resistance booster) matching the stress difference between Hard Coating and Ultra Hard AR coating
A new intermediate SR booster layer (Scratch Resistance booster) matching the stress difference between Hard Coating and Ultra Hard AR coating
The Result
It provides a perfect integration of components, creating a gradual increase of hardness from soft organic substrate to ultra hard mineral surface

* Best UV Protection measured with E-SPF for Crizal Forte UV lenses compared to clear lenses with anti-refl ective coating and equivalent material. E-SPF measures: independent 3rd-party USA - 2011. ** 25 for all Crizal Forte UV lenses, except Essilor Orma® E-SPF=10. Lenses performance only: E-SPF excludes direct eye exposure that depends on external factors (wearer’s morphology, frame shape, position of wear...). *** Study conducted by an independent 3rd-party - 100 wearers - France, 2011.
Exclusive Backside UV Protection
All lenses prevent transmission of UV rays hitting the front side of the lens. However, up until now, even the best eyeglasses did not protect against the remaining danger of the UV rays coming from the back and side of the lens, which can represent up to 50% of damaging UV light.
Crizal Forte UV combines for the first time an exclusive backside UV protection with Crizal’s superior clarity of vision. Thanks to Essilor’s new Broad Spectrum Technology, the thickness of each nanometric layer constituting anti-reflective coating applied to the backside of the lens has been optimized to virtually eliminate UV light reflection into the eyes, while maintaining perfect transparency of the lens.

What is E-SPF?
Definition of the E-SPF
The Eye-Sun Protection Factor (E-SPF) is a new international index certifying the overall UV protection provided by a lens. It is an objective rating system developed by Essilor International which can rate any lens for daily eyewear as well as for sunglasses.
Inspired by the cosmetic industry standard of UV protection, the E-SPF rating system follows a simple pattern:The higher the E-SPF, the better the UV protection. Thanks to this reference UV index, it is now possible for everyone to choose easily the best UV protection for their eyes and the sensitive skin around them.
Developed by Essilor Research & Development, the Eye-Sun Protection Factor follows an impartial measurement protocol, which has been endorsed by an independent third party.
The E-SPF provides a simple yet effective way to grade the total UV protection offered by a lens.

How does E-SPF work?
The higher the E-SPF, the better the UV protection
The Eye-Sun Protection Factor is inspired by the protection index displayed prominently on daily moisturizers, sunscreens and sun-protective clothing, and used to rate effectiveness against ultraviolet radiations : the higher the E-SPF value, the greater the level of UV protection.
Wearing a lens with an E-SPF value of 25 means that your eye is 25 better protected that without any lens. (The E-SPF excludes direct eye exposure from around the lenses*)
E-SPF 25 means your eye is 25 times better protected than without any lens.
All lenses are not equal in terms of UV protection
UV protection is not linked to the color of your lenses. In fact, some transparent lenses can protect you even better than some sun lenses**. Whatever its tint, a lens' protection is a result of a combination of a material and a coating, which varies from one lens to another. As a result, not all lenses are equal in terms of UV protection.
Make sure you get the right protection for your eyes
With the Eye-Sun Protection Factor, you can now compare the levels of UV protection provided by all kinds of eyewear, including clear, photochromic, and sun lenses (tinted or polarized). Ask your Eye-Care Professional for advice.
Up to 25 for corrective clear lenses Up to 50+ for sun lenses
Based on measurements made up until now***, the E-SPF values vary from 2 to a maximum of 25 for daily eyeglass lenses and up to 50+ for sun lenses.
25 is the best rate obtained today for a clear lens with perfect transparency. For sun lenses, the E-SPF can reach a maximum of 50+
*Lens performance only: The E-SPF excludes direct eye exposure that depends on external factors
(wearer's morphology, frame shape, position of eyewear...)
**Your daily eyeglasses can't replace your sunglasses in full sunlight: sunwear equipment offers better visual comfort while protecting a wider area around the eye because frames are usually larger.** April 2012
Why create the E-SPF ?
Why create a new UV protection index for eyewear?
The E-SPF index goes one step further than existing labels by integrating for the first time UV protection provided by both sides of a lens.
The commonly used "100% UVA/UVB" label does not provide full information on the overall UV protection of a lens*. Indeed it doesn't take into account UV radiations reflected on the back of a lens, which can represent up to 50% of all UV received into the eye**.
* Existing mention "100% UV protection" refers to the lens' UV cut rate for the transmission of UVA and UVB hitting the front side of the lens. This mention remains valid. Yet it does not integrate backside UV reflection, which can represent up to 50% of global UV exposure. ** Backside UV reflection importance has been recently emphasized (K.Citek 2008)
