A BREAKTHROUGH DISCOVERY: WE IDENTIFIED THE PRECISE BAND OF LIGHT WITHIN THE BLUE-VIOLET SPECTRUM THAT IS MOST HARMFUL TO RETINAL CELLS.

Protecting eyes from overexposure to Blue-Violet light decreases retinal cell death. The band of Blue-Violet light that is most harmful to retinal cells ranges between 415 and 455 nm (40 nm).

CRIZAL PREVENCIA is the first clear lens on the market to selectively deflect harmful blue-violet light. Crizal Prevencia deflects 20% of harmful Blue-Violet light.

Introducing LIGHT SCAN :

The selective NO-GLARE TECHNOLOGY that works 3 WAYS TO filter OUT harmful light and provide OPTIMAL VISION

• Selectively filters out harmful light (blue-violet & uv)
• Allows beneficial light to pass through (visible light, including blue-turquoise)
• Maintains excellent transparency (clear no-glare lens) for optimal vision at all times

ONLY CRIZAL PREVENCIA HAS EXCLUSIVE LIGHT SCAN™

• Protects the eyes from harmful light (Blue-Violet and UV)
• Allows beneficial light to pass through (visible light, including Blue-Turquoise)

The band of Blue-Violet light that is most harmful to retinal cells ranges between 415 and 455 nm (40 nm).

- Over 4 years of research went into uncovering this breakthrough -

AND PROTECTS EYES

CRIZAL PREVENCIA ALSO PROTECTS EYES from damaging UV RAYS.

Featuring an Eye-Sun Protection factor (E-SPF )
of 25.

Crizal Prevencia provides wearers’ eyes with 25x more protection from UV than with no lens at all.

LIGHT IS BOTH HARMFUL AND BENEFICIAL TO VISION AND HEALTH
NON-visible AND visible LIGHT ARE RISK FACTORS FOR developing EYE DISEASES

• UV is a major risk factor for many severe eye diseases, including cataract
• Blue light (also known as high energy visible, or HEV), at specific wavelengths, is a risk factor for the onset of AMD.
• - AMD is the leading cause of blindness in industrialized countries

SELECTIVELY FILTERS HARMFUL LIGHT

Blue-violet light is present everywhere

• OUTDOORS: Blue-Violet light is emitted all year round in any weather (sunny, cloudy, rainy, etc). This is even true when the light comes through windows in your home, office or car.

• INDOORS: Blue-Violet light is also present throughout the day and night. It is emitted from computers, tablets, most smartphones and compact fluorescent light bulbs.
