Brief summary
This study will occur in two non-dispensing phases: Phase 1 is a non-randomized, non-masked, non-dispensing study where subjects will wear their own contact lenses for approximately 1 hour. Phase 2 is a controlled, randomized, double-masked, contralateral non-dispensing study where the study lenses will be worn in a daily wear modality for approximately 3 hours.

For Phase II, the magnitude of the cylindrical component of the subject's vertex-corrected distance refraction must be between 0.00 D and 1.00 D (inclusive) in each eye. 11.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Photopic Contrast Sensitivity at 6 Cpd | Post screening up to 1 hour during Phase 1 | Photopic (\ 120 cd/m2) contrast sensitivity at 6 cpd was measured on the right eye only with and without a broadband glare source (with glare followed after without glare). Testing included 8 reversals with the last 4 being averaged to provide the contrast threshold. If the reduction (indicating worse contrast sensitivity) in the estimated mean due to the glare source was about 0.1 log units, then it can be concluded that the glare light source was effective and the study can move to Phase 2. |
| Mesopic Contrast Sensitivity at 6 Cpd | Post screening up to 1 hour during Phase 1 | Mesopic (\ 3 cd/m2) contrast sensitivity at 6 cpd was measured on the right eye only with and without a broadband glare source (with glare followed after without glare). Testing included 8 reversals with the last 4 being averaged to provide the contrast threshold. If the reduction (indicating worse contrast sensitivity) in the estimated mean due to the glare source was about 0.1 log units, then it can be concluded that the glare light source was effective and the study can move to Phase 2. |
| Photopic Resolution Acuity Using Landolt C's With a Glare Source | At least 5 minutes post lens fitting up to 2 hours during Phase 2 | Photopic resolution acuity using Landolt C's was measured separately for the right (OD) and left (OS) eyes, using an arcminute scale under bright light conditions (\ 120 cd/m2) with a broadband glare source. The photopic resolution acuity on arcminute scale was converted to logMAR scale for the analysis purpose using a log transformation. Lower values indicate better acuity. |

| Photopic Contrast Sensitivity With a Glare Source | At least 5 minutes post lens fitting up to 2 hours during Phase 2 | Photopic contrast sensitivity was measured for the right (OD) and left (OS) eyes separately under bright light conditions (\ 120 cd/m2) with a broadband glare source. Testing included 8 reversals with the last 4 being averaged to provide the contrast threshold. The area under the log contrast sensitivity function (AULCSF) was derived for the analysis using the trapezoidal rule. Higher AULCSF values indicate better contrast sensitivity. |
| Mesopic Contrast Sensitivity With a Glare Source | At least 5 minutes post lens fitting up to 2 hours during Phase 2 | Mesopic contrast sensitivity was measured for the right (OD) and left (OS) eyes separately under dim light conditions (less than or equal 3 cd/m2) with a broadband glare source. Testing included 8 reversals with the last 4 being averaged to provide the contrast threshold. The area under the log contrast sensitivity function (AULCSF) was derived for the analysis using the trapezoidal rule. Higher AULCSF values indicate better contrast sensitivity. |

Participant flow
Recruitment details
In Phase I, 20 subjects were enrolled and completed this Phase. In Phase 2, 62 subjects were enrolled. Of those enrolled in Phase 2, all 62 were dispensed at least 1 study lens. Of those dispensed, 60 subjects completed Phase 2 while 2 subjects were discontinued from Phase 2. Phase I and Phase II are mutually exclusive. Data collected from Phase I was used to validate the glare light source for evaluating the primary and secondary endpoints in Phase II.

Outcome results
Mesopic Contrast Sensitivity at 6 Cpd
Mesopic (\ 3 cd/m2) contrast sensitivity at 6 cpd was measured on the right eye only with and without a broadband glare source (with glare followed after without glare). Testing included 8 reversals with the last 4 being averaged to provide the contrast threshold. If the reduction (indicating worse contrast sensitivity) in the estimated mean due to the glare source was about 0.1 log units, then it can be concluded that the glare light source was effective and the study can move to Phase 2.
Time frame: Post screening up to 1 hour during Phase 1
Population: All subjects completed Phase 1 without a major protocol deviation excluding subjects recording an increase in mesopic contrast sensitivity with the glare source.
