- Ask the patient to cover one eye with the palm of their hand and read the letters on the chart and then repeat with the other eye.

This test is looking for consistency.

• If the patient is unable to read from 6M move to 3m then 1m.

tests peripheral vision inattention

sit square from the patient around 1M from them.
