    Silicone hydrogel contact lens approved for daily wear and extended wear up to 30 consecutive nights.

Primary Outcome Measures :
  1. Overall Comfort [ Time Frame: 3 months of wear, replacing lenses monthly ]

Secondary Outcome Measures :
  1. Overall Lens Fit [ Time Frame: 3 months of wear, replacing lenses monthly ]
    As assessed by the investigator at study visit using a biomicroscope, which magnifies the appearance of the contact lens on the participant's eye. Lens fit was graded by eye on a 5-point scale, with 2=unacceptably loose, 1=acceptably loose, 0=optimal, -1=acceptably tight, and -2=unacceptably tight
