Arms & Interventions
Lens A (omafilcon B)
Experimental
All participants will wear lens A for 15 minutes (Period 1).
Intervention: Lens A (omafilcon B) (Device)
Lens B (comfilcon A)
Experimental
All participants will wear lens B for 15 minutes (Period 2).
Intervention: Lens B (comfilcon A) (Device)
Outcomes
Primary Outcomes
Overall Fit Acceptance
Time Frame: After 15 minutes of continuous wear
Overall fit acceptance will be measured on scale of (0-4) where (0=Should not be worn and 4=Perfect)
