Glasses and Sunglasses Lens Coating Explained
Still CR39, but with a clear tough coating on both sides to prevent day to day scratches. Not scratch proof (no lens material is) but does help extend the life of lenses. Can still be tinted.
Still CR39 plastic, but with a multi layer coating to help reduce ghost imaging. Very useful for night driving, and those working on computers, as it helps reduce the glare. Also has excellent cosmetic benefits, as it enables everyone else to see straight through to your eyes.
Comes with a scratch resistant coating as standard.
Uncoated lenses lose over 10% of incident light to reflections. Reflection Free lenses reduce this to less than 1%.
All camera lenses have this coating.
We recommend Essilors" Crizal Forte as our supercoated lens.

Premium AR Efficiency
The optimisation stack layers combined with a limited number of layers brings a premium AR efficiency with low colour intensity.
|Smudge resistant||Thanks top to the HSD Process™ smudges are much more repelled from the surface pf the lens and smudge resistance is improved.|
|Scratch resistant||The SR Booster™ layer creates a gradual increase of hardness for the ultimate performance on scratch resistance.|
|Dust repellence||The i-technology™ allows perfect integration of the anti-static layer. Lenses are thus virtually free of dust.|
|Water repellence||The Slide Fx™ measures the hydrophobic performance of the lens. The lower the sliding angle needed to make the droplet slide, the higher the water repellence performance.|
