Using the highest index of refraction and the most advanced material, Pentax produces lenses that are thinner and lighter than they have ever been before. High prescriptions no longer mean thick, chunky lenses that can only be glazed into heavy frames.
Pentax stands above ordinary glass and plastic lenses. Thanks to the anti-reflective lens enhancements that can be an added feature of Pentax lenses, a more natural vision that is clearer, sharper and easier on the eye can by enjoyed. Night-time drivers see reduced dazzle from approaching headlights and daytime wear cuts tiring reflections from sunlit surfaces.
