Thin Lenses

High-index
Aspheric
Polycarbonate

Newer designs have decreased the distortion that was a problem with this material in the past.

This was the first lens material introduced that was thinner and lighter than CR-39. It's most significant benefit is its impact resistance - 10x stronger than plastic. Because of this feature we use it for sport and safety frames, kids glasses, and drill mounts.
