Outcome Measures
Primary Outcomes (1)
Mean Time Post-blink to 15% Distortion of the Projected Rings After 12 Hours of Lens Wear
The participant blinked twice, then kept eye open. Circular images were projected onto tear film layer located on the surface of the contact lens. Measuring software automatically detected areas where the tear film destabilized after the blink. The time to 15% destabilization of the tear film was calculated. A longer time indicates a more stable tear film. The right eye was evaluated.
Day 1, Hour 12, each period
Secondary Outcomes (1)
Mean Speed of Tear Film Break-up at 15 Seconds Post-blink After 12 Hours of Lens Wear
Hour 12

Eligibility Criteria
You may qualify if:
- Must sign an Informed Consent form;
- Adapted, current soft contact lens wearer;
- Required contact lens prescription within the power range specified in the protocol (+6.00 to -10.00 diopters (D));
- Cylinder ≤ -1.00 D in both eyes at Visit 1;
- Vision correctable to 0.1 logarithm of the Minimum Angle of Resolution (logMAR) or better in each eye at distance with pre-study lenses at Visit 1;
- Willing to wear study lenses up to 12 hours and attend all study visits;
- Able to be successfully fitted with study lenses;
- Unstable tear film with a NIK-BUT value below 13 seconds in either eye without lenses;
You may not qualify if:
- Any ocular infection, inflammation, abnormality, or active disease that would contraindicate contact lens wear;
- Any use of systemic or ocular medications for which contact lens wear could be contraindicated, as determined by the Investigator;
- Use of artificial tears and rewetting drops during the study;
- Monocular (only 1 eye with functional vision) or fit with only 1 lens;
- Any abnormal ocular condition observed during Visit 1;
- History of herpetic keratitis, ocular surgery, or irregular cornea;
- Pregnant or lactating;
- Participation in any clinical study within 30 days of Visit 1;
- Current MyDay® or DAILIES® AquaComfort Plus® lens wearer;

Limitations and Caveats
There was a high censoring rate observed with the objective measurements and therefore there are limitations to the conclusions that may be drawn.
