Brief summary
The purpose of this study is to evaluate end of day (EOD) visual acuity (VA) at distance when wearing Precision1™ contact lenses compared to Acuvue® Moist contact lenses.
Detailed description
The expected duration of subject participation in the study is 1-8 days, with 3 scheduled visits (Screening, Dispense, Exit).
Interventions
Daily disposable silicone hydrogel contact lenses indicated for the optical correction of refractive ametropia (myopia and hyperopia)

Inclusion criteria
* Able to understand and sign an approved Informed Consent form * Successful wear of spherical soft contact lenses for distance correction in both eyes during the past 3 months for a minimum of 5 days per week and 8 hours per day * Best corrected VA of logMAR 0.10 or better in each eye * Willing to discontinue artificial tears and rewetting drops during the study * Able to wear contact lenses within the protocol-specified sphere power range * Other protocol-specified inclusion criteria may apply.
Exclusion criteria
* Any anterior segment infection, inflammation, or abnormality or disease that contraindicates contact lens wear, as determined by the Investigator * Any use of systemic or ocular medications for which contact lens wear could be contraindicated, as determined by the Investigator * History of ocular or intraocular surgery, including refractive surgery, and/or irregular cornea * Wearing habitual contact lenses in an extended wear modality (routinely sleeping in lenses for at least 1 night per week) over the last 3 months prior to enrollment * Previous 3 years or current wearers of Acuvue Moist or DAILIES TOTAL1® contact lenses * Other protocol-specified
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| End of day (EOD) visual acuity at distance | Day 1, after 8 hours of wear | Visual acuity (VA) will be measured in logarithm of the minimum angle of resolution (logMAR). A lower logMAR value indicates better visual acuity. |
