Print the free eye chart on regular 8 1/2 x 11-inch paper
Tack or tape the chart to a windowless wall in a well-lit room at eye level
Measure ten feet from the wall
Cover one eye (if you wear glasses for distance vision, keep them on)
Have another person point to each line as you read the letters out loud and keep track of which letters you get right
Continue to the bottom row or until you can no longer read the letters
Write down the number of the smallest line where you identified the majority of letters correctly (Ex. If you were able to read 5 out of 8 letters on line 8, you would write 20/20.)
Cover the other eye and repeat steps 5-7
That depends on the age of the person being tested. A 3- to 4-year-old should be able to read the 20/40 line, and a 5-year-old the 20/30 line. Older children and adults should be able to read the majority of letters on the 20/20 line.
If you notice any results that fall outside these standards, be sure to schedule an eye exam with your Vision Source doctor.
