Primary Outcome Measures :
  1. 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.
