One of a new breed of lens capable of being worn night and day for 30 days continuously, the Air Optix Night & Day Aqua derives its special attribute from a material which transmits the highest level of oxygen of any available contact lens (oxygen starvation being the main danger in overwearing traditional contact lenses), plus class-leading deposit resistance means each lens feels as clean when removed as it did when inserted.

Material: 76% polymer (Lotrafilcon A)
