Multi-Center 2-Week Clinical Evaluation of Three Silicone Hydrogel Contact Lenses

Inclusion Criteria:

- Be no less than 18 and no more than 39 years of age.

- Sign Written Informed Consent and investigator to record this on Case Report Form.

- Be willing and able to adhere to the instructions set out in the protocol.

- Be an existing successful daily wear soft contact lens wearer. For the purposes of
this study this means wearing lenses for at least 6 hours per day, 5 days per week for
the last month.

- No extended wear in the last 3 months.

- Subjective refraction must result in a vertex corrected spherical contact lens
prescription between -1.00 and -6.00 diopters.

- Have refractive astigmatism less than or equal to 1.00 diopters (D) in both eyes.

- Achieve visual acuity of 6/9 (20/30) or better in each eye.

- Require a visual correction in both eyes (no monovision allowed).

- Have normal eyes with no evidence of abnormality or disease. For the purposes of this
study a normal eye is defined as one having: no amblyopia, no evidence of lid
abnormality or infection (including blepharitis/meibomitis), no conjunctival
abnormality or infection, no clinically significant slit lamp findings (i.e. stromal
edema, vascularization, infiltrates or abnormal opacities), no other active ocular
disease.

Exclusion Criteria:

- Requires concurrent ocular medication.

- Clinically significant corneal stromal haze, corneal vascularization, tarsal
abnormalities, bulbar hyperemia, limbal hyperemia, or any other abnormality of the
cornea that would contraindicate contact lens wear.

- Clinically significant corneal staining

- Requires presbyopic correction (i.e. Not using any presbyopic correction and measured
add power of less than +1.00 diopters).

- Has had refractive surgery.

- Has had eye injury/surgery within 8 weeks immediately prior to enrollment for this
study.

- Abnormal lacrimal secretions.

- Pre-existing ocular irritation that would preclude contact lens fitting.

- Keratoconus or other corneal irregularity.

- Hard, hybrid or Rigid Gas Permeable lens wear in the previous 8 weeks.

- Any systemic illness which would contraindicate lens wear or the medical treatment of
which would affect vision or successful lens wear.

- Diabetic.

- Infectious disease (e.g., hepatitis, tuberculosis) or an immunosuppressive disease
[e.g., Human immunodeficiency virus (HIV)].

- History of chronic eye disease (e.g. glaucoma or Age Related Macular Degeneration).

- Pregnancy, lactating or planning a pregnancy at the time of enrollment.

- Participation in any concurrent clinical trial or in last 30 days
