Two smaller groups 7.5M to 1.5M for repetitive testing (20/50, 6/15 to 20/10, 6/3 equiv.).

Can be wall-mounted.

The design of the Tumbling E is similar to that of grating stripes. This is helpful in the detection of Against the Rule Astigmatism. Also, the Tumbling E chart has proven to be nearly equal to the gold standard Landolt C chart when it comes to visual acuity thresholds. Tumbling E charts are useful for testing patients of multiple ages and languages.
