Distance Visual Acuity
This outcome measures vision while subjects are looking at objects in the distance and is measures in logMARs.logMAR is the logarithm of the minimum angle of resolution.The ideal is 0.0 and represents 20/20 Snellen acuity.logMAR values \>0.00 indicate vision poorer than ideal and values\<0.0 indicate vision greater than ideal
Time frame: after 1 week of wear
Near Visual Acuity
This outcome measures vision while subjects are looking at objects near to them and is measured in logMARs. logMAR is the logarithm of the minimum angle of resolution.The ideal is 0.0 and represents 20/20 Snellen acuity.logMAR values \>0.00 indicate vision poorer than ideal and values\<0.0 indicate vision greater than ideal.
Time frame: after 1 week wear
Subject Vision
Subjects responded to "How would you rate the overall quality of vision with these study contact lenses" using the following scale: 1=poor, 2=fair, 3=good, 4=very good, 5=excellent.
Time frame: after 1 week wear
