Eligibility
Inclusion criteria
Potential subjects must satisfy all of the following criteria to be enrolled in the study: The subject must: 1. Read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form. 2. Appear able and willing to adhere to the instructions set forth in this clinical protocol. 3. Be between 18 and 39 (inclusive) years of age at the time of screening. 4. By self-report, habitually wear spherical soft silicone hydrogel contact lenses in both eyes in a daily wear or daily disposable wear modality (i.e. not extended wear modality). Habitual wear is defined as a minimum of 6 hours of wear per day, for a minimum of 5 days per week during the past 30 days. 5. Have a habitual contact lens prescription that is current within the prior 6 months, and they must have worn that prescription for at least 2 weeks prior to entering the study. 6. Possess a wearable pair of spectacles that provide correction for distance vision. Inclusion Criteria at Baseline Evaluation 7. The spherical equivalent of the subject's vertex-corrected distance refraction must be between -1.00 and -6.00 DS (inclusive) in each eye. 8. The magnitude of the cylindrical component of the subject's vertex-corrected distance refraction must be between 0.00 and 1.00 DC (inclusive) in each eye. 9. The best corrected, monocular, distance visual acuity must be 20/25or better in each eye.
