6. The subject's optimal vertexed spherical equivalent distance correction must be between -1.00 and - 5.00D.
7. Any cylinder power must be ≤ -0.75D.
8. The subject must have visual acuity best correctable to 20/25+3 or better for each eye.
9. The subject must have normal eyes (no ocular medications or ocular infection of any type).
10. The subject must read and sign the Statement of Informed Consent.
11. The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.

Exclusion Criteria:

1. Ocular or systemic allergies or disease which might interfere with contact lens wear.
2. Systemic disease or use of medication which might interfere with contact lens wear.
3. Clinically significant (grade 3 or worse) corneal edema, corneal vascularization, corneal staining, or any other abnormalities of the cornea which would contraindicate contact lens wear.
4. Clinically significant (grade 3 or 4) tarsal abnormalities or bulbar injection which might interfere with contact lens wear.
5. Any ocular infection.
6. Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
7. Any color deficiencies - to the best of the subject's knowledge.
8. Pregnancy or lactation.
9. Diabetes.
10. Infectious diseases (e.g. hepatitis, tuberculosis) or an immuno-suppressive disease (e.g. HIV).
11. Habitual contact lens type is toric, multifocal, or is worn as extended wear.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Lens Fit Acceptance	Lens fit acceptance (whether acceptable or unacceptable) was assessed by the Investigator at dispensing.	10-15 minutes post lens fit

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Binocular Snellen Visual Acuity (VA)	Binocular Snellen VA was assessed at dispensing by Investigator using a Snellen vision chart. Subjects were analyzed based on their performance on a Snellen Vision chart exam in the study lenses in an effort to measure how well the lenses perform for vision correction.	10-15 minutes post lens fit
Corneal Staining	Corneal staining type was graded in a 5-point scale over the 5 corneal regions by Investigator using a slit lamp; 0=none, 1=trace, 2=mild, 3=moderate, and 4=severe. Maximum grade of corneal staining type over the 5 corneal regions was categorized either absence or presence of corneal staining for the analysis.	After 6-9 days of lens wear
