Designed by two low vision doctors. This chart has a 20/630 size number as well as numbers & tumbling “E’s” that are 20/500, 20/400, & 20/317 sizes. These take the memory out of acuity testing. The 20/250 page & below have four numbers of the same size. This allows you to test each eye individually without concern for memoriztion. Also, by observing which number is seen first, the tester can decide which part of the field has the best fixation. Chart lists size by logmar & Snellen equivalent to 20/20.
