A test for quickly measuring low contrast visual acuity at 25%, 10%, 5%, 2.5%, and 1.25% contrast by measuring the distance at which the symbols are seen. 10M symbols correspond to visual acuity 0.10 at 1 meter, 0.05 at 0.5 meters and 0.3 at .3 meters. VA values are thus easy to calculate. This test includes a table for conversion to Snellen equivalent VA values. Includes a response key, instructions, and 6 pages.
