• The subject must be interested in wearing contact lenses.
• The subject must be at least 18 years old or less than 40 years of age at the time of consent.
• The subject's vertexed spherical cylindrical refraction must result in a contact lens prescription for each eye that is available in the investigator's choice of study contact lens material(s).
• The subject must have best corrected visual acuity of 20/30 or better in each eye.
• The subject must require visual correction in both eyes.
• The subject must be a lapsed wearer (defined as, any non-contact lens wearer requiring optical correction who has been previously fitted in and has previously purchased contact lenses but has since discontinued contact lens wear for any reason more than 6 months prior to the time of consent).
• The subject must have normal eyes (i.e., no ocular medications or infections of any type).

Exclusion criteria

• Currently pregnant or lactating (subjects who become pregnant during the study will be discontinued).
• Any ocular or systemic allergies or diseases that may interfere with contact lens wear.
• Any systemic disease, autoimmune disease, or use of medication, which may interfere with contact lens wear.
• Entropion, ectropion, extrusions, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions, aphakia, or moderate or above corneal distortion.
• Any previous, or planned, ocular or intraocular surgery (e.g., radial keratotomy, photorefractive keratectomy (PRK), LASIK, etc.)
• Any grade 3 or greater slit lamp findings (e.g., edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) on the FDA classification scale, any previous history or signs of a contact lens related corneal inflammatory event (e.g., past peripheral ulcer or round peripheral scar), or any other ocular abnormality tha may contraindicate contact lens wear.
• Any ocular infection.
• Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
• Participation in any contact lens or lens care trial within one year prior to study enrollment.
• History of binocular vision abnormality or strabismus.
• Any infectious disease (e.g., hepatitis, tuberculosis) or contagious immunosuppressive disease (e.g., HIV), by self report.
• Employee of the investigational clinic (i.e., Investigator, Coordinator, or Technician).
