Primary Outcome Measures

Name	Time	Method
Lens Comfort Likert Response at Day 30	Day 30	Subject indicated agreement with the following statement, "These lenses provided the same excellent comfort at the end of the month as they did at the beginning of the month" using a 4-point Likert scale, where 1=Strongly disagree, 2=Disagree; 3=Agree; 4=Strongly agree. The Top 2 responses (agree, strongly agree) were calculated and reported as a percentage of all responses. Both eyes were rated together. This outcome measure was prespecified for the AIR OPTIX COLORS arm only.

Secondary Outcome Measures

Name	Time	Method
Lens Comfort Likert Response at Day 14	Day 14	Subject indicated agreement with the following statement, "These lenses provided the same excellent comfort at the end of two weeks as they did at the beginning of the two weeks" using a 4-point Likert scale, where 1=Strongly disagree, 2=Disagree; 3=Agree; 4=Strongly agree. The Top 2 responses (agree, strongly agree) were calculated and reported as a percentage of all responses. Both eyes were rated together. This outcome measure is prespecified for the AIR OPTIX COLORS arm only.
Lens Comfort 1-10 Scale Response	Day 30	Subject was instructed, "Please rate your comfort with the study lenses," using a scale from 1-10, where 1=poor and 10=excellent. Both eyes were rated together.
