CSV-1000 ETDRS LogMAR Tests
The CSV-1000 ETDRS provides a full range of LogMAR testing (20/200 to 20/10) at a test distance of 8 feet using standardized luminance. The smaller footprint of the instrument allows its use for testing in the typical-size examination rooms, ie 8’ X 12’ rooms. If testing at 4 meters is desired, a different test face can be used with a more narrow range of acuity tested (20/125 to 20/5). To learn more about the CSV-1000.
