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.
