This test is used to assess the level of a patient's functional visual disability. The Esterman
tests are designed to be done using a patient's everyday correction. If the patient does not
require glasses to function normally, perform the test without correction. If the patient does
wear glasses to function normally, perform the monocular or binocular test using the patient's
glasses. Do not use trial lenses. You still must use the eye patch when testing with the
Monocular version of the Esterman test. Testing instructions are provided in Section 5.
