  • Corrected Distance Binocular Visual Measurement in Normal Illumination Reported as Binocular Distance Visual Acuity [ Time Frame: After 1 week of wear ]
    Tested while reading charts distant to the subject with both eyes together in normal lighting. This outcome is measured in logMAR units (logarithm of the minimum angle of resolution). A logMAR acuity of 0.0 equates to 20/20 Snellen acuity and is considered normal. Positive logMAR values indicate poorer vision and negative values denote better visual acuity.
  • Corrected Near Binocular Visual Measurement in Normal Illumination Reported as Binocular Near Visual Acuity [ Time Frame: After 1 week of wear ]
    Tested while reading charts at 40 cm with both eyes together in normal lighting. This outcome is measured in logMAR units (logarithm of the minimum angle of resolution). A logMAR acuity of 0.0 equates to 20/20 Snellen acuity and is considered normal. Positive logMAR values indicate poorer vision and negative values denote better visual acuity.
Measure: subject comfort ratings, visual ratings, purchase intent, lens preference [ Time Frame: 2 weeks ]
