Air Optix for Astigmatism are ideal for those who need to wear their lenses for extended periods of time on a regular basis.
Lens comfort is heavily dependent on the amount of oxygen that is able to reach the surface of the eye. Patented TriComfort Technology means Air Optix for Astigmatism allow up to 6 times more oxygen to pass through than other silicone hydrogel contact lenses.
Air Optix for Astigmatism also excel at retaining moisture, making them less prone to drying out, no matter where and when you wear them. The surface of each lens is specially designed to resist the build-up of protein deposits to help ensure they feel just as comfortable at the end of your use cycle as they do at the beginning. Although each pair is intended to be used daily for up to a month, they are so comfortable your optician may suggest a schedule that includes constant wear over 6 nights and 7 days. Whatever schedule you use, Air Optix for Astigmatism contact lenses feel so natural you'll quickly forget you're wearing them at all.

|Base Curve (BC)|
|Oxygen permeability (Dk/t)|
It indicates the amount of oxygen which passes through the lens. The oxygen permeability is an key indicator of the lens material. It determines how much oxygen (which is necessary for proper performance) receives a cornea of our eyes. The higher the value, the better. Dk/t is common used and it states: the Dk per thickness of the lens. Usually for a lens at -3.00D, which makes it easier to compare different lenses brands. Ranges from 10-20 Dk/t to over 170 Dk/t.
