How to read the results of a visual acuity test visual acuity is typically measured in fractions or decimals. the first number in the fraction refers to the testing distance, and the second number refers to the distance someone with "normal" vision could see the same details from. Most precision vision eye charts carry the letter size designation in m-units. this makes it easy to calculate the visual acuity if the chart is used at any other distance than the one for which it was designed by inserting the new test distance (in meters) and the letter size (in m-units) directly into the above formula.
If the patient reads all the letters on the 20/30 line you would record their vision as 20/30. if the patient is reading the 20/30 line and reads 3 out of the 5 letters correctly you would record that vision as 20/30-2.
