Primary Outcome Measures

Name	Time	Method
Visual Performance (LogMar)	30 Minutes Post Insertion	Distance time controlled Visual Performance (LogMAR) was assessed for each subject eye under bright-illumination high-contrast lighting conditions at 4m using an ETDRS chart. The average visual performance (LogMAR) was reported for each study lens.
CLUE Handling	30 Minutes Post Insertion	CLUE Handling is assessed using the Contact Lens User Experience (CLUE™) Questionnaire. CLUE™ is a validated patient-reported outcomes questionnaire to assess patient experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact lens-wearing population in the US, ages 18-65. Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable / positive response. 97% of the scores fall within 0 and 120 (mean +/- 3XSD).
Percentage of Eyes With Acceptable Mechanical Lens Fit	30 Minutes Post Insertion	Mechanical lens fit will be assessed for each subject and eye using a slit lamp. Lens fit is a binary response and 'Yes' = Acceptable Fit and 'No' = Unacceptable Fit. Lens fit is assessed using Lens centration, limbal exposure, primary gaze movement, up-gaze movement, edge lift, lens tightness. Unacceptable fit will be declared if there is any of the following present: limbal exposure, edge lift, excessive movement in primary or up-gaze or insufficient movement in primary gaze and up-gaze. The Percentage of subject eyes with acceptable lens fit will be reported.
Percentage of Eyes With Acceptable Cosmetic Lens Fit	30 Minutes Post Insertion	Cosmetic lens fitting is assessed for each subject eye in the primary gaze position without a slit lamp. Cosmetic lens fit is a binary response and is reported as acceptable or unacceptable. The Percentage of subject eyes with acceptable cosmetic lens fitting is reported.
