Collection: ETDRS Vision Test Charts

ETDRS, stemming from the Early Treatment Diabetic Retinopathy Study, improves visual acuity testing with equal step size between rows and consistent letter spacing on a logarithmic scale, offering advantages over previous tests like Snellen and Sloan; often referred to as a LogMAR test, available in various formats, including back-lit charts for standardized luminance testing.
