Primary Outcome Measures:
  • Visual Acuity [ Time Frame: Screening visit (Visit 1) and one week follow-up(Visit 3) ]
    Visual acuity(VA) measured at the screening visit (all eligible participants) while wearing spectacles and the VA measured at the end of study (Visit 3) 1-Week wearing PureVision2 HD lenses. VA wearing spectacles vs. VA wearing PureVision2 HD Lenses, lower the number the better the VA.

Secondary Outcome Measures:
  • Preference for Test Lens [ Time Frame: During the movie (Visit 2) ]
