loW VisioN distaNcE acuity chaRt
loW VisioN Visual acuity Book
Designed by two low vision doctors. The 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 memorization. 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.

loW VisioN lEttER tEst chaRt Chart contains SLOAN letters in LogMAR increments. Optotypes range in size from 50M to 5M
on the main chart and from 6M to 1M on the inside chart.
When used at 1 meter, the main chart covers the entire Low Vision range from 1/1(20/1000, 0.02) to 1/5(20/100, 0.2 and extends to 1/1 (20/20, 1.0) on the inside chart. A cord with an occluder is attached to accurately maintain the 1-meter testing distance.
The back of the card contains proportionally spaced reading segments from 4M to 0.6M in Times Roman font. From 3M on, two sets are provided to avoid memorization.
Each line contains the same number of letters and spaces. Diopter ruler and instructions are included.
Most acuity vision charts have the patient identify single letters in a line. Continuous text chart are designed to simulate everyday reading tasks for patients by using actual sentences. These sentences are calibrated to have a specific number of letters and spaces to create an equal test.
LV4001 $74.95
tumBliNg E Pad
Printed with large 20/200 E on one side and a series of four 20/20 tumbling E’s on the other calibrated
to a 20 ft. distance.
tumBliNg “E” foldiNg distaNcE chaRt
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.
