Study Overview
Brief Summary
This is a multi-site, 5-visit, double-masked, dispensing study comparing an investigational contact lens with currently-marketed contact lenses. The objective of the study is to evaluate the comfort of the lenses when worn for 30 (-2/+6) days on daily wear modality.

Outcomes
Primary Outcomes
Frequency of Lens Awareness Individual Item
Time Frame: 1 month Follow-up
Frequency of Lens Awareness was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are scaled as (Always, Frequently, Occasionally, Rarely, Never or Don't Know). Only the number of participants that reported Rarely or Never (Top-Two-Box) was reported here.
Subjective Overall Comfort Composite Score
Time Frame: Up to 1 month Follow-up
Subjective Overall Comfort was evaluated using the Contact Lens User Experience Comfort scores (CLUE). 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.Range is 0 to 120. CLUE was collect at Baseline, Post Lens Fit 1-, 2-, 3- and 4- week follow-ups.
Overall Comfort Individual Item
Time Frame: 1 month follow-up
Overall Comfort was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Responses are on a 5 likert scale (Excellent, Very Good, Good, Fair and Poor). Only the percentage of participants that reported Excellent or Very good (Top-Two-Box) was reported here.
Comfort at the End of the Day Individual Item
Time Frame: 1 month Follow-up
Comfort at the End of the Day was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are on a 5 like-rt scale (Excellent, Very Good, Good, Fair and Poor). Only the percentage of participants that reported Excellent or Very good (Top-Two-Box) was reported here.
Comfort Each and Everyday Individual Item
Time Frame: 1 month Follow-up
Comfort each and everyday was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are on a 5 likert scale (Excellent, Very Good, Good, Fair and Poor). Only the percentage of participants that reported Excellent or Very good (Top-Two-Box) was reported here.
Frequency of Experiencing Dryness Individual Item
Time Frame: 1 month Follow-up
Frequency of Experiencing Dryness was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are scaled as (Always, Frequently, Occasionally, Rarely, Never or Don't Know). Only the number of participants that reported Rarely or Never (Top-Two-Box) was reported here.
Making Your Eyes Feel Moist Throughout the Day Individual Item
Time Frame: Up to 1 month Follow-up
Making your eyes feel moist throughout the day was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are on a 5 likert scale (Excellent, Very Good, Good, Fair and Poor). Only the percentage of participants that reported Excellent or Very good (Top-Two-Box) was reported here.
