Air Optix for Astigmatism

Ciba Vision’s Air Optix for Astigmatism silicone hydrogel contact lenses are designed to offer the highest oxygen transmissibility of any available soft toric lens, so eyes can stay healthy. It features breakthrough Precision 8I4 design which minimizes interaction with the lower lid for excellent comfort, exceptional stability and consistent rotation. Patented surface treatment of Air Optix for Astigmatism resists deposits to contribute to healthy lens wear. It provides clear vision and exceptional comfort consistently from lens to lens.

Lens Material
The lens material is 33% water and 67% lotrafilcon B, a fluoro-silicone containing hydrogel which is surface treated. Lenses contain the color additive phathalocyanine blue, a light blue handling tint, which helps make them easier to see when handling.
