Outcomes
Primary Outcomes
Comfort Preference
Time Frame: Dispensing (Baseline) and 2 weeks
Subjective assessment for comfort preference for each lens pair. Choices: fanfilcon A lens, enfilcon A lens, No preference.
Comfort (Subjective Rating Scale)
Time Frame: Dispensing (Baseline) and 2 weeks
Participant rating for comfort at dispense visit and at the 2 week follow-up on a subjective rating scale (0-100, 0=cannot be worn. Causes pain,100=Cannot be felt ever)
Secondary Outcomes
No secondary outcomes reported
