- •The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.
- •The subject must be at least 18 and not more than 70 years of age.

- •The subject's required spherical contact lens prescription must be in the range of -0.50 to -9.00D in each eye.
Exclusion Criteria

- •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 that may contraindicate contact lens wear.
- •Any known hypersensitivity or allergic reaction to OPTI-FREE® PureMoist® Contact Lens Solution.
- •Any ocular infection.
- •Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
- •Monovision or multi-focal contact lens correction.
- •Participation in any contact lens or lens care product clinical trial within 14 days prior to study enrollment.
- •History of binocular vision abnormality or strabismus.

Outcomes
Primary Outcomes
Subjective Overall Comfort (Using CLUE )
Time Frame: 2 weeks
Contact Lens User Experience Comfort scores (CLUE) is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.
Subjective Overall Vision (Using CLUE )
Time Frame: 2 weeks
Contact Lens User Experience Vision scores (CLUE) is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.
