PRIMARY outcome

Timeframe: after 7 +/-1 days of lens wear

Population: Analysis is on those subjects who were enrolled, randomized to a study arm, and completed the study.

The contract Lens Experience (CLUE)TM questionnaire 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.
