Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Corrected Distance Binocular Visual Measurement in Normal Illumination Reported as Binocular Distance Visual Acuity	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.	After 1 week of wear	No
