Primary Outcome Measures:

Objective Vision Assessments: High Contrast Distance Visual Acuity [ Time Frame: After 1 hour of lens wear ] [ Designated as safety issue: No ]
Tested with charts distant to the subject with both eyes together in normal lighting conditions. The unit of measure is logMAR units (logarithm of the minimum angle of resolution) A logMAR acuity of 0.0 equates to 20/20 Snellen acuity. Positive logMAR values indicate poorer vision and negative values denote better visual acuity than baseline 20/20 value.
Objective Vision Assessments: High Contrast Intermediate Visual Acuity [ Time Frame: After 1 hour of lens wear ] [ Designated as safety issue: No ]
Tested with charts at intermediate distance (100cm)distant to the subject with both eyes together in normal lighting conditions. The unit of measure is logMAR units (logarithm of the minimum angle of resolution) A logMAR acuity of 0.0 equates to 20/20 Snellen acuity. Positive logMAR values indicate poorer vision and negative values denote better visual acuity than baseline 20/20 value.
Objective Vision Assessments: High Contrast Near Visual Acuity [ Time Frame: After 1 hour of lens wear ] [ Designated as safety issue: No ]
Tested with charts set at near point (40cm)distant to the subject with both eyes together in normal lighting conditions. The unit of measure is logMAR units (logarithm of the minimum angle of resolution) A logMAR acuity of 0.0 equates to 20/20 Snellen acuity. Positive logMAR values indicate poorer vision and negative values denote better visual acuity than baseline 20/20 value.

Secondary Outcome Measures:

Subjective Overall Vision: High Contrast Distance Visual Quality [ Time Frame: After 1 hour of lens wear ] [ Designated as safety issue: No ]
Subjects instructed to rate Vision quality at distance, intermediate and near vision (OU) using a 0-100 numerical scale where 0 = poor and 100 = excellent.
Subjective Vision Assessments: High Contrast Intermediate Visual Quality [ Time Frame: After 1 hour of lens wear ] [ Designated as safety issue: No ]
Subjects instructed to rate Vision quality at distance, intermediate and near vision (OU) using a 0-100 numerical scale where 0 = poor and 100 = excellent.
Subjective Vision Assessments: High Contrast Near Visual Quality [ Time Frame: After 1 hour of lens wear ] [ Designated as safety issue: No ]
Subjects instructed to rate Vision quality at distance, intermediate and near vision (OU) using a 0-100 numerical scale where 0 = poor and 100 = excellent.
