The dot visual acuity test--a new acuity test for children.

A new visual acuity test is described for children between the ages of 2 and 4 years who are unable to respond to the tumble E games. For children old enough to respond to both tests, the visual threshold are the same. Fifty percent of the children who could not respond to the tumble E game will be able to be tested with this new method. The new is rapid, inexpensive, and cannot be memorized, thereby allowing the test to be given at frequent intervals.
