PRIMARY outcome

Timeframe: 1-Week Follow-up

Population: All subjects that completed all study visits without a major protocol deviation.

Distance visual acuity was assessed for each subject in both eyes under a high luminance high contrast condition using ETDRS (Early Treatment Diabetic Retinopathy Study) charts.

SECONDARY outcome

Timeframe: 1-Week Follow-up

Population: Subjects that completed all study visits without a major protocol deviation.

Overall quality of vision was assessed using the Contact Lens User Experience™ (CLUE) questionnaire. 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 with a range of 0-120.
