The third generation of silicone hydrogel materials in Avaira ® Vitality ™ remains naturally humid, with no surface treatments. This, together with the higher water content, ensures a powerful, comfortable lens.
In addition, the patented Aquaform ® Technology from CooperVision provides a contact lens that is naturally hydrophilic. Aquaform ® Technology works with longer siloxane chains, which means that the lens requires fewer silicones for high oxygen permeability. The technology also creates charged areas within the lens material that form hydrogen bonds with water molecules. This keeps the water in the lens, which ensures more comfort and less deposits.
