Content

Essilor has always aimed to develop innovations that meet the expectations of eyeglass wearers. 
 

In today’s society, product durability is more important than ever. Essilor has seen firsthand how the unpredictability of our environment and wearers’ unintentional behavior affect clarity of vision.
 

With this in mind, Essilor researchers have defied the limits of physics to offer a new generation of coating:  Crizal® Rock™. Its unique high-resistance technology allows this new Crizal® coating to eliminate the optical compromise between scratch resistance and smudge resistance for durability like never before**.  

To assess the resistance of Crizal® Rock™ in the hectic lives of wearers, Essilor R&D has developed a thorough protocol of technical and real-life tests: the Lifeproof multi-test. Not only did Crizal® Rock™ have a high technical performance and high consumer satisfaction, but it held up well in risky everyday situations, offering the best combination against scratches and smudges* while ensuring high UV protection and minimal reflections.
