Primary Outcome Measures :
  1. Comfort After Insertion [ Time Frame: 3 months ]
    Comfort after insertion of contact lens (30 seconds to 1 minute), as interpreted by the subject and reported by the subject as a single, retrospective evaluation of 3-month's wear time. Comfort after insertion was measured on a 10-point scale, with 1 being poor and 10 being excellent.
