Sphere/Asphere
Innova Vision Sphere and Asphere (Etafilcon A) Soft Contact lenses are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes in powers from -20.00 to +20.00 diopters. The lenses may be worn by persons who exhibit astigmatism of 2.00 diopters or less that does not interfere with visual acuty.

Toric
Innova Vision Toric (Etafilcon A) Soft Contact lenses are indicated for the correction of ametropia (myopia or hyperopia with astigmatism) in aphakic and non-aphakic persons with non-diseased eyes in powers from -20.00 to +20.00 diopters and astigmatic corrections from -0.25 to -10.00 diopters.

Multifocal
Innova Vision Multifocal (Etafilcon A) Soft Contact lenses are indicated for the correction of refractive ametropia (myopia and hyperopia) and emmetropia with presbyopia in aphakic persons with non-diseased eyes in powers from -20.00 to +20.00 diopters and with add powers from +0.25 to +4.00 diopters. The lenses may be worn by persons who exhibit astigmatism of 2.00 diopters or less that does not interfere with visual acuity.

Multifocal Toric
Innova Vision Multifocal Toric (Etafilcon A) Soft Contact lenses are indicated for the optic correction of distance and near vision in presbyopic phakic persons with non-diseased eves in powers of -20.00 to +20.00 diopters with add powers from +0.25 to +4.00 diopters and astigmatism corrections from -0.25 to -10.00 diopters.

Eye Care Practitioners may prescribe the Innova Vision Hydrogel (Etafilcon A) Soft (Hydrophilic) Contact lenses for frequent/planned replacement wear, with cleaning, disinfection and scheduled replacement or for single-use disposable wear.

When prescribed for frequent/planned replacement, the Innova Vision Hydrogel (Etafficon A) Soft (Hydrophilic) Contact Lens is to be cleaned. rinsed and disinfected each time the lens is removed. The contact lens is to be discarded after the recommended wearing period as prescribed by the Eye Care Professional. When prescribed for frequent/planned replacement wear, the lenses may be disinfected using a chemical disinfection only.

When prescribed for single-use disposable wear, Innova Vision Hydrogel (Etafilcon A) Soft (Hydrophilic) Contact Lens is to be discarded after each removal.

Innova Vision Hydrogel (Etafilcon A) Soft (Hydrophilic) Contact Lens is available as spherical and aspherical lenses manufactured by cast-molding method. The material is a high water content (58% wt/wt) material. The hydrogel lens' material is a random copolymer of 2-hydroxyethyl methacrylate (HEMA) and methacrylic acid (MAA), cross-linked with ethylene glycol dimethacrylate (EGDMA) and 1,1,1-trimethylolpropane trimethacrylate (TMPTMA) a via UV photo-polymerization. Innova Vision Hydrogel (Etafilcon A) Soft (Hydrophilic) Contact Lens is tinted with Reactive Blue 19 to enhance the visibility for for handling and contains 2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyl-phenyl]ethyl as an additive for ultraviolet blocking purpose. The average transmittance in the UVB region is less than 5% and less than 30% in the UVA region.

The properties of the lens are:
Chord Diameter: 13.00 mm to 15.00 mm
Center Thickness 0.080 mm to 0.580 mm
