Detailed Description

Subjects will wear two different contact lens study products in a cross-over fashion. Each study product type will be worn for approximately 14 days. A washout period of 2-4 days will occur prior to the first wear period and between the two wear periods. Subjects will be expected to attend 7 office visits. The total duration of study participation is approximately 40 days with approximately 28 days of lens wear.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Mean Binocular Visual Acuity at Distance (4 Meters) at Week 1
Time Frame: Week 1 (Day 7 -0/+1 days) of each wear period. A wear period was 14 days (-0/+2 days) according to randomization assignment.
Visual Acuity (VA) was assessed at a distance of 4 meters with both eyes together (binocular) under high contrast, high illumination lighting with study lenses in place. VA was measured using letter charts and recorded in the logarithm of the minimum angle of resolution (LogMAR). A LogMAR value of 0 equates to 20/20 Snellen VA (normal distance eyesight), with negative LogMAR values representing better than 20/20 VA. The LogMAR VA scale ranges from -0.30 (20/10 Snellen) to 1.00 (20/200 Snellen). No hypothesis testing was pre-specified for this endpoint.
Week 1 (Day 7 -0/+1 days) of each wear period. A wear period was 14 days (-0/+2 days) according to randomization assignment.
