Crizal® No-glare Lenses
In today’s competitive eyewear market, brick-and- mortar customers have high expectations. Modern lenses must be durable, improve optical clarity and provide other benefits while utilizing the latest in research and technology. Address your patients’ needs and exceed their expectations by recommending a single product that does it all: Crizal® No-Glare lenses.
FAMILY OF LENSES
Crizal’s family of lenses allows you to customize benefits based on the individual needs of your patients. The Crizal Easy UVTM lens provides a comprehensive series of lens benefits. If a patient describes a past frustration with dirty lenses, Crizal Alizé UVTM is formulated to be even easier to clean. Where durability is chief concern, Crizal Avancé UVTM is specially designed with two times the normal scratch resistance. For the clearest vision possible, particularly when driving at night, the Crizal Sapphire UVTM lens is outstanding at reducing glare. Crizal’s newest addition, Crizal® Prevencia® lenses, selectively filters at least 20% of Harmful Blue Light  and is meant for heavy digital screen use.
Crizal lenses also provide an important — and unique — benefit. While polycarbonate, Trivex, and high index materials inherently protect the eye from UV light entering the front of the lens, 10 - 50% of that UV light is missed, entering the eye via the back and side of the lens. Crizal products are uniquely designed with UV protection from the backside of the lenses.
There are many reasons why patients should be instructed to shield their eyes from UV light, including cancer — 90% of skin cancer occurs on the face and neck, with 5-10% on the eyelids . UV exposure also contributes to an increased risk for cortical cataracts . In addition, UV damage causes 90% of premature aging signs around the eyes.
While patients may be accustomed to the value of anti-reflective treatments, they may not realize how important backside protection can be. A discussion with patients about UV protection during their lens selection can reinforce these important features of their new eye wear. Crizal products provide comprehensive UV protection in clear lenses and are the first no-glare lens to carry the Good Housekeeping Seal.
Just how are features-laden Crizal products made? Using the Crizal Avancé design as our model, the graphic (above) reveals an intricate system. A scratch resistant layer is applied in equal thickness to the front and back of a lens. The SR BoosterTM layer, a proprietary Crizal feature with a hard “glass-like” effect, is also applied to both sides. Next, anti-reflective layers are added, and the back side’s application gets an extra boost of UV protection. Also included in this process on both sides of the lens is an antistatic treatment to actively repel dust and dirt. To cap things off, the High Surface DensityTM (HSD) Super Hydrophobic layer greatly improves cleanability; however, this process makes the lens so slippery that a temporary Pad Control System is added to improve grip during edging (this is easily removed with a soft cloth upon completion). The total thickness of this entire lens process is less than 0.5μ (microns), a measurement visible only with a microscope.
 Harmful Blue Light falls between 415-455nm on the light spectrum and is suspected to be most toxic to retinal cells. See Arnault E, Barrau C, Nanteau C, Gondouin P, Bigot K, et al. (2013).
