Avaira Vitality toric are naturally moist two-week silicone hydrogel contact lenses. Avaira Vitality toric contact lenses are made from a unique material that attracts and binds water within the lens itself, keeping them moist and comfortable without the need for surface treatments or wetting agents. Avaira Vitality toric contact lenses manufactured by CooperVision offer many reasons why contacts feel comfortable. There's more to Avaira's lens material than an inherent ability to attract and retain water. To help keep your eyes clear, white, and healthy looking, Avaira Vitality toric lenses are also exceptionally breathable, meaning more oxygen is able to pass through the lens to your eye. But to provide a truly exceptional level of comfort, there is one general rule a lens must follow: moist is good.
