About
A low contrast test is a special way to measure how well eyes function in low light situations and/or are able to distinguish objects from similarly colored or shaded backgrounds. Testing is identical to the measurement of visual acuity at a high contrast level. The 2.5% test is the most practical in clinical use. Available in 5 contrast levels: 1.25%, 2.5%, 5%, 10%, and 25%. This chart can either be wall mounted or used in an ESV1200, ESV1500, or a Model A+ illuminated cabinet. Each chart includes a response key and instructions.
These charts have line sizes ranging from 10/63 to 10/4 (3/19 to 3/1.2) equivalent. The other equivalents featured on these charts are letter size, 20 foot, 6 meter, decimal, and LogMAR.
Dimensions: 9" x 14" (22.9 cm x 35.6 cm).
Testing distance: 10 feet/3 meters.
