These lenses permit up to 7 times more oxygen permeability compared to traditional hydrogel toric contact lenses, therefore, they provide perfect vision quality and comfort. Thanks to this high oxygen permeability Air Optix for Astigmatism protect astigmatic patients from a condition associated with low oxygen level also known as oxygen deficiency. Because of that, your eyes always feel and look white and healthy. Patented surface modification technology guarantees the effect of biocompatible, deposit-resistant surface as well as excellent hydration. Traditional contact lenses for the correction of astigmatism are usually associated with inconsistent vision, especially after blinking, when the lens reorients on your eye. This problem has been overcome by the introduction of a wide optic zone built into the lens so that there are no problems with looking through them, even after blinking.
