Enhance Your Eye Health with CRIZAL® PREVENCIA™
CRIZAL® PREVENCIA™ – Lasting Protection for Eye Health
CRIZAL® PREVENCIA™ is an Essilor innovation that selectively filters harmful light to improve eye health and protect against premature eye aging. It’s designed to guard your eyes from the cumulative damage of UV and Blue-Violet light—factors that not only contribute to digital eye strain but also accelerate retinal cell damage and cataract development.
1. Glare and Its Impact on Visual Processing
-
Nature of Glare:
Glare is the excessive, scattered light entering your eyes from overhead lights, reflective surfaces, direct sunlight, and even screen reflections. This stray light creates visual “noise” that disrupts image clarity and forces your eyes to work harder to focus. -
Increased Visual Demand:
When glare reduces the contrast between text and background, your eyes must strain to differentiate details. This extra effort overworks the eye muscles, leading to fatigue.
2. Digital Screens and Eye Fatigue
-
High Focus and Concentration:
Extended screen use requires constant focus, locking your gaze and demanding continuous accommodation. This sustained effort intensifies eye strain. -
Blue Light Emission:
Digital screens emit blue light, which in high quantities adds to visual discomfort. When combined with glare, this high-energy light further exacerbates eye fatigue. -
Reduced Blink Rate:
Concentrating on screens often reduces your blink rate by up to 60%. With less frequent blinking, the natural tear film isn’t replenished, speeding up tear evaporation and setting the stage for dry, irritated eyes by the end of the day.
3. The Link Between Eye Fatigue and Dry Eyes
-
Tear Film Instability:
The tear film—a multi-layered, protective coating on your eyes—relies on regular blinking to stay evenly distributed. A reduced blink rate means the film thins out and tears evaporate faster, leading to dry eyes. -
Feedback Loop of Discomfort:
As fatigue increases, you may squint or strain even more, further reducing blinking. This creates a cycle of worsening eye strain and dryness that can, over time, lead to chronic dry eye syndrome.
4. How CRIZAL® PREVENCIA™ Provides Lasting Protection
-
Selective Light Filtering for Healthier Eyes:
CRIZAL® PREVENCIA™ selectively filters out harmful UV and Blue-Violet light—the very wavelengths that contribute to retinal cell damage (reducing cell death by 25%*), premature eye aging, and cataract development.

Advanced Anti-Reflective and Protective Technology:
This premium lens solution not only minimizes glare by reducing stray light reflections but also repels dust, smudges, and water droplets. With 30% less back surface UV reflection when paired with E-SPF 35 index lenses, CRIZAL® PREVENCIA™ offers complete protection against the enemies of clear vision. -
Durable Clarity and Optimal Vision:
Engineered for optimal vision and durable transparency, these lenses let essential visible light (including beneficial Blue-Turquoise) pass through—supporting natural sleep/wake cycles, mood, and cognitive performance. For enhanced protection, CRIZAL® PREVENCIA™ can also be combined with the Eye Protect System. -
Guaranteed Quality:
Enjoy peace of mind with a full two-year guarantee against scratches and manufacturing defects.
5. Additional Strategies for Combating Eye Fatigue and Dryness
-
Optimize Your Environment:
Adjust ambient lighting and screen positioning to minimize glare and reduce the burden on your eyes. -
Practice Regular Breaks:
Adopt the 20-20-20 rule—every 20 minutes, look at something 20 feet away for at least 20 seconds—to relax your eye muscles and promote a healthy blink rate. -
Stay Hydrated:
Maintain adequate hydration and a comfortable humidity level in your workspace to support a stable, protective tear film. -
Supplemental Relief:
If dryness persists, consider using lubricating eye drops to ease discomfort throughout the day.
Conclusion
The combined impact of glare, prolonged digital screen exposure, and reduced blinking can lead to significant eye fatigue and dry eyes by day’s end. CRIZAL® PREVENCIA™ offers a cutting-edge solution that not only minimizes glare and enhances visual clarity but also provides lasting protection against harmful UV and Blue-Violet light. Upgrade your prescription lenses today with CRIZAL® PREVENCIA™ to safeguard your vision, reduce eye strain, and preserve overall eye health—all day, every day.
