Distance Bright Illumination Binocular Visual Performance Reported as Visual Acuity Primary · 5 minutes after insertion

Tested with both eyes together in bright lighting, reading charts distant to the subject. This outcome is measured in logMAR units.LogMAR stands for the logarithm of the minimum angle of resolution. Ideal is 0.0 and represents 20/20 Snellen acuity. logMAR values \> 0.00 indicate vision poorer than the ideal and values \<0.00 indicate vision greater than the ideal.

Near Bright Illumination Binocular Visual Performance Reported as Visual Acuity Primary · 5 minutes after insertion

Tested with both eyes together in bright lighting reading charts near to the subject. This outcome is measured in logMAR units.LogMAR stands for the logarithm of the minimum angle of resolution. Ideal is 0.0 and represents 20/20 Snellen acuity. logMAR values \> 0.00 indicate vision poorer than the ideal and values \<0.00 indicate vision greater than the ideal.

Type of Corneal Staining Primary · after 1 week of lens wear, for each lens type

Investigator rated type of corneal staining as either 0=none, 1=micropunctate, 2=macropunctate, 3=coalesced, or 4=patch(\> or = to mm).

Overall Subjective Vision Primary · after 1 week of lens wear, for each lens type

Subject rated the overall quality of vision with the study contact lenses. 5=excellent, 4=very good, 3=good, 2=fair, 1=poor.
