Monocular Visual Acuity
Monocular distance Snellen visual acuity (VA) scores were coverted to the algorithm of the minimal angle of resolution (LogMAR) scale based on the following formula: LogMAR = Log10 (VA/20) - a\*VAR, where Log10 = base 10 logarithm, VA = the Snellen denominator score, a = LogMAR stepsize coefficient and VAR = letter gained or missing in addition to the Snellen denominator score.
Time frame: Dispensing
Lens Fit Acceptance
