Study Summary
This is a single visit, brand-masked, non-dispensing, 2×2 bilateral crossover study. Each subject will be bilaterally fitted with one of the two test articles in each of the study periods in a random order with a 5-minute washout period in between study lenses.
Primary Outcome
Visual acuity on logMAR (Logarithm of Minimal Angle of Resolution) scale was evaluated at distance (4 meters) under high luminance low contrast and low luminance high contrast lighting conditions using ETDRS (Early Treatment Diabetic Retinopathy Study) charts. Letter-by letter results calculated the visual performance score for each chart read. logMAR scores closer to zero, or below zero, indicate a better visual acuity. A logMAR visual performance score of 0.0 is equivalent to Snellen visual ac
Interventions
- DEVICE etafilcon A with cosmetic pattern
- DEVICE 1-Day Acuvue DEFINE Vivid Style
