Description
Lighthouse ETDRS® Chart R LH 9142 (2110)
Developed by New York Lighthouse International. Constructed with the same precision, accuracy, and methodology as traditional ETDRS® charts.
Lines are of equal difficulty. Geometric progression in letter size from line to line. Letter size is only variable. Can be wall-mounted.
ETDRS® charts use a series of three charts with different permutations of optotypes. The use of three ETDRS® eye charts (Chart 1, 2 & R) to test the visual acuity of one patient prevents memorization and helps increase accuracy and consistency in results.
