Arm && Interventions

Group	Intervention	Description
FRESHLOOK® COLORBLENDS	Phemfilcon A contact lens with color	Phemfilcon A contact lens with color worn in daily wear modality for 4 weeks, with a replacement pair dispensed at 14 days. Lenses were worn bilaterally for a minimum of 5 days per week, 8 hours per day.

Primary Outcome Measures

Name	Time	Method
Subjective Rating of Overall Comfort	Up to Day 28	Overall comfort, as rated by the participant on a 10-point scale, with 1 being poor and 10 being excellent. The participant rated both eyes together by providing one single rating.

Secondary Outcome Measures

Name	Time	Method
Subjective Rating of Overall Vision	Up to Day 28	Overall vision, as rated by the participant on a 10-point scale, with 1 being poor and 10 being excellent. The participant rated both eyes together by providing one single rating.
Proportion of Subjects Preferring Study Lens (Strongly or Somewhat)	Day 28	Participants were asked to compare the study lenses to their habitual lenses using a 5-point scale: strongly prefer study lenses, somewhat prefer study lenses, no preference, somewhat prefer habitual lenses, and strongly prefer habitual lenses, where 'study lenses' refer to either test or control depending on the treatment group. Proportion of subjects preferring study lens is reported as the percentage of participants who strongly or somewhat preferred the study lens.
