Avaira lenses are produced by CooperVision and are some of the most comfortable contacts money can buy. These lenses incorporate the Aquaform Comfort Science Technology that allows the contact to transmit high levels of oxygen to the eye, which will help keep the eyes clear and moist. The Avaira contact lens therefore will stay most and comfortable throughout each day they are worn and are very good contacts for those that have sensitive eyes. These contacts are softer and more flexible than most lenses, therefore allowing some movement with the eye making them more comfortable to wear than traditional lenses. Avaira also has a UV light blocker in the lens to help protect the eye. These contact lenses are designed for wear for one to two weeks and should be replaced at the end of this interval. The lens material is a Polymer composed of enfilcon A, which makes the contact incredibly soft to the touch.
