Visual acuity test
Charles Brown, OD
This test measures how clearly you see. We will ask you to identify different letters of the alphabet printed on a chart (Snellen chart) or a screen positioned some distance away. The lines of type get smaller as you move down the chart. Each eye is tested separately. Your near vision also may be tested, using a card with letters similar to the distant eye chart that is held at reading distance.
