Notations for testing at 40 cm (16 in.)
Acuity range 8M to .20M (20/400, 6/120 to 20/10, 6/3 equiv.)
Front and back sides are 10% low Contrast
Different optotype configurations on each side to reduce memorization
40 cm (16 in.) cord attached to maintain proper viewing distance
Measures 18 X 23 cm ( 7 X 9 in.)
Near vision chart uses 10% calibrated contrast sensitivity levels on each side of the test. Also, chart uses two different configurations of optotypes to minimize memorization. This helps in more accurate vision test results. Near point chart also includes a cord to help control viewing distances for more precise testing.
