The purpose of this study is to compare ACUVUE® ADVANCE® Plus contact lenses made prior to process qualification (prePQ) against the ACUVUE® ADVANCE® Plus lenses made after the process qualification (postPQ).

Inclusion Criteria:

• The subject must be at least 18 years of age and no more than 39 years of age.
• The subject is a current spherical soft contact lens wearer and willing to wear the study lenses on a daily wear basis for the duration of the study (minimum of 6 hours per day).
• The subject's optimal vertexed spherical equivalent distance correction must be between -1.00 and - 5.00D.
• Any cylinder power must be ≤ -0.75D.
• The subject must have visual acuity best correctable to 20/25+3 or better for each eye.
• The subject must read and sign the Statement of Informed Consent.
• The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.

Exclusion Criteria:

• Ocular or systemic allergies or disease which might interfere with contact lens wear.
• Systemic disease or use of medication which might interfere with contact lens wear.
• Clinically significant (grade 3 or 4) corneal edema, corneal vascularization, corneal staining, or any other abnormalities of the cornea which would contraindicate contact lens wear.
• Clinically significant (grade 3 or 4) tarsal abnormalities or bulbar injection which might interfere with contact lens wear.
• Any ocular infection.
• Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
• Pregnancy or lactation.
• Diabetes.
• Infectious diseases (e.g. hepatitis, tuberculosis) or an immuno-suppressive disease (e.g. HIV).
• Habitual contact lens type is toric, multifocal, or is worn as extended wear.

44 persons enrolled, 42 completed as cohort, 2 dropped due to: 1 non-trial related adverse event, and 1 protocol deviation
