Primary Outcome Measures

Name	Time	Method
Subject Reported Overall Quality of Lens Vision Using the Contact Lens User Evaluation (CLUE) Questionnaire	After 7 to 9 days of lens wear	The overall quality of lens vision was assessed using the CLUE questionnaire after 7-9 days of follow-up. The CLUE Questionnaire is a validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses 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 with a range from 0-120.
Subject Reported Overall Lens Handling Using the Contact Lens User Evaluation (CLUE) Questionnaire	After 7 to 9 days of lens wear	The overall lens handling was assessed using the CLUE questionnaire after 7-9 days of follow-up. The CLUE Questionnaire is a validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses 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 with a range of 0-120.
