Calligraphy PV progressives incorporate two breakthrough design technologies that dramatically improve performance over conventional progressive lenses.

Atoral Aspheric Optics Replacing conventional spherical curves with Atoral Aspheric

Back-Surface Progression Moving the progressive addition from front surface

Perfect Vision Technology

Atoral Aspheric Optics Wider distance clear zones Reduced side distortion Thinner and lighter lenses

Back-Surface Progression Wider near reading zones Reduced sway and distortion Better visual comfort

30% wider and clearer distance vision

Up to 25% wider near reading zones

Up to 50% less sway and distortion
