Scratch Protection Coating
Light weight hard resin lenses can be more easily scratched than glass lenses. Special coatings have been developed to help protect lenses for normal scratching. The modest additional cost for such scratch coating is usually a prudent investment.
TD2 Hard Coating
This new scratch coating is the ultimate anti-scratch protection for hard resin lenses. It is so effective that it has a two year guarantee against scratches.
Special anti-reflective coatings are now available for spectacle lenses, much like those used for fine camera lenses. These coatings are particularly effective for reducing eye fatigue for computer operators and anyone driving at night. And, of course, anti-reflection coatings on lenses enhance appearance by removing all distracting reflections.
Crizal (integrates an Anti-Reflection Coating & Hard Coating)
Time spent in front of computer screens and in harsh fluorescent lighting situations produces eye fatigue and stress from glare. By reducing glare, Crizal lenses make you feel more comfortable in your work environment. In fact, Crizal lenses have been proven in clinical studies to dramatically reduce eye fatigue caused by unwanted light reflections that create glare. Also, studies have shown that Crizal lenses allow your eyes to recover more quickly from glare caused by bright oncoming headlights when driving at night.
