Avaira
is a 2-week disposable silicone hydrogel contact lens from CooperVision. Avaira contact lenses
are made from a unique material that attracts and binds water within the lens
itself, keeping those lenses moist and comfortable without the need for additional
lens surface treatments or "wetting agents" like other silicone
hydrogel contacts. Additionally, the advanced
aspheric optics of Avaira's Aberration-neutralizing system enhances vision by
minimizing spherical aberrations inherent in both the lens and the human eye.
Lens Material
The lens material, enfilcon A, is
composed of silicone macromers cross linked with other monomers, incorporating
phthalocyanine blue as an integrated, handling tint.
