Esterman Testing
The Esterman test is designed to be conducted using a patient’s functional correction. If the patient
does not require glasses to function normally, perform the test without correction. If the patient
does require glasses to function normally, perform the test using the patient’s glasses. Do not use
trial lenses.
Steps to Perform:
1. Press SHOW TEST LIBRARY.
2. Press SPECIALTY TESTS.
3. Choose either ESTERMAN MONOCULAR or ESTERMAN BINOCULAR.
When performing the Binocular test, the following set of instructions will display on the screen
when you press START:
• Move chin rest to the far right position.
• Have patient place chin in the chin cup on the left.
• Do not use the trial lens holder.
• Do not use an eye patch.
• Move patient’s head to center eye monitor between patient’s eyes.
• Patient may wear spectacles for this test.
After you have followed the instructions, press OK. The test will begin.
When performing the Esterman Monocular test, you will not get a set of instructions. Testing is
identical to a standard test, except the patient wears his or her glasses instead of looking through a
trial lens. You must still use the eye patch with the Monocular test. You may also use Gaze Tracking
if you wish (Model 740
i , 745 i , and 750 i ).
