Primary Outcome Measures:
  • Comfort After Insertion [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    Comfort after insertion (30 seconds to 1 minute) as interpreted and reported by the participant on a questionnaire as a single, retrospective evaluation of three months' wear time. Comfort after insertion was measured on a 10-point scale, with 1 being poor and 10 being excellent.

  • Eye injury or surgery within twelve weeks of enrollment.
  • Pre-existing ocular irritation that would preclude contact lens fitting.
  • Currently enrolled in an ophthalmic clinical trial.
