Technology
Harmful light filtration
Crizal Prevencia selectively filters out harmful UV and Blue-Violet light. By reducing Blue-Violet exposure, Crizal Prevencia helps supports retinal cell survival(1). Crizal Prevencia blocks UV rays from passing through the front of the lens and prevents UV rays from reflecting off of the back of your lens into your eye, resulting in an E-SPF rating of 35, the highest E-SPF index on a clear lens for optimal UV protection(5).
