Product: Crizal Rock
Top Line: Essilor is introducing Crizal Rock, which the company calls “The most scratch-resistant Crizal No-Glare lenses ever made.”
Close Up: Crizal Rock lenses are three times more scratch-resistant than entry-level Crizal products and two times easier to clean than its main competitors after extensive smudging, according to Essilor.
“Essilor is a company built on a history of innovation and providing ECPs with the most advanced lens technologies—such as Varilux, the number one progressive lens brand recommended by optometrists and opticians,” said Sherianne James, chief marketing officer and senior vice president of customer engagement at Essilor. “Our latest innovation, Crizal Rock, is life-proof, so ECPs know they are providing patients a scratch- and smudge-resistant lens equipped to handle everyday activities and wearers’ imperfect eyeglass habits while still providing the excellent clarity of vision with reduced glare and UV light protection that ECPs and patients love in every Crizal lens.”
To ensure it released a lens equipped to meet real needs of wearers, Essilor developed a series of tests to assess a lens’ resistance to scratches and smudges. In this battery of tests, designed to reproduce the daily activities of an eyeglass wearer, Crizal Rock lenses were subjected to drop tests, improper cleaning and placed unprotected in loaded purses to be jumbled and shaken. The lenses also underwent a new sand-resistance test which measures scratch resistance after 300 shake-cycles in a sand tray. The results of these tests and more, all certified by independent third parties, prove that Crizal Rock lenses are the most scratch-resistant Crizal No-Glare lenses ever made.
“Rigorous testing of new products is a central focus for Essilor R&D to ensure we are offering the best quality products to our customers,” said Pete Hanlin, senior director of professional services & ophthalmic operations. “Essilor has always been at the forefront of pushing boundaries of quality standards in the optical industry. With this new sand resistance test, Essilor has yet again developed a new standard of testing no-glare coatings.”
Vital Stats: Crizal Rock lenses feature Essilor’s High-Resistance Technology, a combination of specific oxides proven to resist scratches and dust. Thanks to their high surface density superhydrophobic topcoat and anti-particulate layer, Crizal Rock lenses also have excellent smudge resistance and are easy to clean, Essilor said. In addition, Crizal Rock lenses reduce glare and provide optimal protection against UV light with protection from backside UV reflections. Like all Crizal No-Glare lenses, Crizal Rock lenses carry the Skin Cancer Foundation seal of recommendation.
Crizal Rock lenses are available now from coast to coast across lab networks and through all major managed vision care providers. Crizal Rock is available with Varilux progressive lenses, Eyezen enhanced single vision lenses, and other Essilor lens designs and materials.
