Healthy adult males or females age ≥ 18 years of age with signed informed consent.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Eyestrain Related to Glare | Up to 12-Week Follow-up | Eyestrain related to glare was assessed at the 2-, 4-, 8- and 12- week follow-up visits using an 11-item questionnaire. This questionnaire assesses patient-experience attributes of soft contact lenses. Derived eyestrain related to glare scores using Item Response Theory (IRT) follow a normal distribution with a mean of 50 and a standard deviation of 10. Scores in this study ranged from 30 to 70. Lower scores indicate better performance. This questionnaire is still under development and the data collected is considered exploratory. |
| Distance Monocular logMAR Visual Acuity (VA) | Up to 12-Week Follow-up | Distance logMAR Visual Acuity was assessed for each subject and eye at 2-, 4- 8- and 12-weeks. The average logMAR visual acuity for each lens and time point was reported. Lower values of logMAR indicate better vision. |
| Percentage of Eyes With Grade 3 or Higher Slit Lamp Findings | Up to 12-Week Follow-up | Slit lamp findings were graded using a FDA Grade Scale, 0 = None, 1 = Slight, 2 = Moderate, 3 = Significant, 4 = Advanced. Measurements were taken in each subject eye at the initial visit, 2-4-8- and 12-week follow-ups. A new response variable was derived by dichotomizing the data as follows: 1 if a Grade 3or higher SLF was observed and 0 otherwise. The Percentage of eyes with Grade 3 or higher SLFs was reported for each lens and time point. |

| Contact Lens Wearing Time | Up to 12-Week Follow-up | Contact lens wearing time (hours) was self-reported by each subject at the 2-, 4-, 8- and 12-week follow-ups. The average contact lens wearing time (hours) for each lens and time point was reported. |
| Percentage of Eyes With Subject Reported Symptoms Problems or Complaints | Up to 12-Week Follow-up | Symptoms, problems and complaints are subject reported and were collected for each subject eye at the 1-, 2-, 4-, 8- and 12-week follow-up evaluations. The data is reported as a binary outcome of yes if a subject experience a problem or complaint or no otherwise. Symptoms, problems and complaints include the following: Burning/Stinging, Itchiness/Scratchiness, Dryness, Lens Awareness, Grittiness/Foreign Body Sensation, Redness, Irritation/Discomfort, Cloudy/Blurry/Hazy, Variable Vision and Other The Percentage of subjects eyes with symptoms, problems or complaints was reported for each lens and time point. |
