Monocular visual performance (logMAR) was evaluated under 3 conditions (1.high luminance and high contrast, 2. High Lumiance Low Contrast and 3. Low Luminance High Contrast with distance goggles) at 4 meters using Early Treatment Diabetic Retinopathy Study (ETDRS) charts. Letter-by-letter results were calculated to ascertain 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 acuity of 20/20.
