    Outcome Measures

    Primary Outcome Measures

    1. Initial Comfort [Baseline]

      Initial Comfort will be assessed bilaterally by the participant at time of dispense. Initial Comfort will be graded on a 1-10 scale (10=cannot be felt, 1=painful).

    Secondary Outcome Measures

    1. End of Day Comfort [Day 7]

      End of Day Comfort will be assessed by the participant as a retrospective, bilateral evaluation of 1 week of wear. End of Day Comfort will be graded on a 1-10 scale (10=cannot be felt, 1=painful).

    2. Overall Comfort [Day 7]

      Overall Comfort will be assessed by the participant as a retrospective, bilateral evaluation of 1 week of wear. Overall Comfort will be graded on a 1-10 scale (10=cannot be felt, 1=painful).

    3. Overall Handling at Time of Removal [Day 7]

      Overall Handling at Time of Removal will be assessed by the participant as a retrospective, bilateral evaluation of 1 week of wear. Overall Handling at Time of Removal will be graded on a 1-10 scale (10=excellent, very easy; 1=unmanageable).
