Crizal Sapphire UV lens offers clarity

Essilor claims to offer new levels of clarity with its Crizal Sapphire UV lens which reduces reflections across a wide range of incident angles offering improved protection and better aesthetics.

Andy Hepworth, professional relations manager, said lenses had traditionally been designed to reduce reflections hitting the lens at or around five degrees from the perpendicular. Sapphire UV is designed to reflect at angles at 45 degrees to 45 degrees across the perpendicular, 90 degrees in total he said.

The lens uses a stack of coating chemicals designed to do away with the compromise between anti-reflective (AR) performance and UV protection. This results in a lens which offers ESPF 36 UV protection and reduces tiring and distracting unwanted reflections, said Essilor.
