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.
