Group Intervention Description Control, senofilcon A senofilcon A Subjects received Control lens, senofilcon A during the first two weeks of the study then Test lens, senofilcon A in the last two weeks of the study. Test, senofilcon A senofilcon A Subjects received Test lens, senofilcon A during the first two weeks of the study then Control lens, senofilcon A in the last two weeks of the study.
- Primary Outcome Measures
Name Time Method Subjective Overall Comfort (Using CLUE ) 2 weeks Contact Lens User Experience Comfort scores (CLUE) is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.
