7. How does a visual acuity test work? Most visual acuity tests follow these steps: Let Clients stand or sit 20 feet away from the chart or screen. Let the visual technician eye care ask client to cover one of your eyes (usually with your Cup hand or a paddle). Your eye care specialist will ask you to slowly read the chart, starting at the top with the biggest row of letters or symbols. You’ll keep reading smaller rows until you can’t see the letters or symbols clearly. After you finish with one eye, you’ll switch eyes and do the test again.

8. Results and Follow-Up What type of results you get from a visual acuity test? The results of the visual acuity test will be a fraction that represents your uncorrected vision. You’re probably heard of the most famous expression of vision-20/20 vision If it 20/20 vision, you can see an object that is 20 feet away clearly. People sometimes think 20/20 vision means perfect vision. But it actually just means average or typical vision. Most people don’t have 20/20 vision without wearing glasses or contacts. In fact, only around 35% of adults in the U.S. have natural 20/20 vision

9. Take home Note Visual Acuity test is done at all time during regardless of first or follow up visit. A wall chart with letters on it read from top to bottom is a common part of a routine eye exam. Encourage patient to be honest about how much they can or can’t see No matter which kind of visual acuity test eye care specialist uses. Almost everyone who has a visual acuity test and gets the help they need to correct their vision feels better. Visual Acuity is more comfortable, safer and convenience than they were before. Talk to your client they have any questions or notice any changes in their vision or in their eyes.
