Features: 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.
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.
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 says. 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.
Availability: Crizal Rock lenses are available at our optical shop, and is available with Varilux progressive lenses, Eyezen enhanced single vision lenses, and other Essilor lens designs and materials. We are excited to bring this new lens option to you!
