visual acuity chart for at home testing (ADULT)

---

• Print out the chart below. When printed, the largest letter at the top of the chart should be just under an inch (23 millimeters) tall.
• Measure 10 feet from a wall with no windows, and place a chair at this point.
• Tape or pin the chart on the bare wall, level with the eyes of the person you will test as he or she sits in the chair.
• Have the person being tested sit in the chair, 10 feet from the chart. Make sure the chart is level with his or her eyes.
• Have the person being tested cover one eye. If he or she uses eyeglasses for distance vision, the glasses should be worn during the test.
• Write down the number of the smallest line seen correctly (the line with more than half of the letters correctly identified).
• Now repeat the test with the other eye covered and record the results.
• WHAT IS NORMAL

An adult should be able to read the 20/20 line.

If not - schedule an appointment with us.

Explain to your child that you are going to play a “pointing game.” Using the practice E card, show him or her how to point in the same direction that the E is “pointing.” 

• Have your child sit in the chair 10 feet from the chart, holding the cover over one eye without applying any pressure. Do not let the child peek. If your child wears glasses, he or she should wear them during the test.
• Point at each of the Es, starting with the largest. Have your child point in the direction the E is pointing.
• Write down the number of the smallest line your child can correctly see (more than half of the Es correctly identified).
• Then repeat the test with the other eye covered. If your child is tired, you may wish to test the other eye at a different time.
• WHAT IS NORMAL - 

By age 3 or 4 - a child should be able to see the 20/40 line

By age 5 - 20/30 line 

An older child or adult should be reading the 20/20 line.
