A Study to Evaluate the Product Feasibility of Two New Silicone Hydrogel Contact Lenses

Inclusion criteria

• Have physiologically normal anterior segments not exhibiting clinically significant biomicroscopy findings.
• Be adapted wearers of soft contact lenses, wear a lens in each eye, and each lens must be of the same manufacture and brand.
• Be correctable through spherocylindrical refraction to 32 letters (0.3 logMAR) or better (distance, high contrast) in each eye.
• Be myopic and require lens correction from -0.50 diopters (D) to -6.00 D in each eye.
• Must agree to wear the study lenses on a daily wear basis for the duration of the study.
• Must be willing to use a lens care system on a regular basis.
• If the subject requires a Washout Period, the subject must be willing to discontinue contact lens wear and be willing to wear either spectacles or no lenses during this Washout Period.

Exclusion criteria

• Not correctable to 32 letters (0.3 logMAR) in each eye with soft spherical contact lenses.
• Have an active ocular disease, any corneal infiltrative response or are using any ocular medications.
• Have worn gas permeable (GP) contact lenses within last 30 days or PMMA lenses within last 3 months.
• Any scar or neovascularization within the central 4mm of the cornea.
• Any Grade 2 or greater finding during the slit lamp examination, Subjects with corneal infiltrates, of ANY GRADE, are not eligible.
• Any "Present" finding during the slit lamp examination that, in the Investigator's judgment, interferes with contact lens wear.
• Anisometropia (spherical equivalent) of greater than 2.00 D.
• Any systemic disease affecting ocular health.
• Using any systemic or topical medications that will affect ocular physiology or lens performance.
• Aphakic.
• Amblyopic.
• Allergic to any component in the study products.
• Have had any corneal surgery (ie, refractive surgery).
• Currently wear monovision correction, multifocal, or toric contact lenses.
• Ocular astigmatism greater than 1.00 D in either eye.
