Primary Outcome Measures:
  • Overall Preference [ Time Frame: 4 weeks of wear ] [ Designated as safety issue: No ]
    Overall preference when comparing study lenses to "habitual" lenses, as interpreted by the participant and reported on a questionnaire as a single, retrospective evaluation of four weeks' wear time. Overall preference was measured on a 5-point Likert scale as follows: Strongly Prefer Study Lenses; Somewhat Prefer Study Lenses; No Preference; Somewhat Prefer "Habitual" Lenses; Strongly Prefer "Habitual" Lenses.
