Designed for standardized visual acuity assessment, including Best Corrected Visual Acuity (BCVA), the ETDRS 2000 Series Sloan Letter Chart 2 uses proportionally spaced lines in a standardized ETDRS/LogMAR format for accurate and repeatable measurement. Line sizes range from 10/100 to 10/5 (3/30 to 3/1.5) equivalent, with letter size, 20-foot, 6-meter, decimal, and LogMAR equivalents.

The ETDRS 2000 Series is a revised version of the Original ETDRS series, with line difficulty designed to remain consistent across the chart for standardized testing and clinical research applications.

Compatible with the ESV3000™ ETDRS Clinical Trial Standardized Viewer and ESC2000™ Illuminated ETDRS Clinical Trial Cabinet.
