1
Hold the printed chart at the distance you would normally hold a book or newspaper. Examples of printable eye charts can be found in the Resources section of this article or can be supplied by a retailer of reading glasses.
-
2
Read each line of the chart, starting with the one in the largest print. Do this without wearing any reading glasses you currently possess.
-
3
Stop reading when you reach a line on the chart where the letters appear blurred or indistinct and where you have trouble making out the words.
-
4
Check the magnification level noted against the line on the chart that you have reached. This is expressed as a decimal such as: +1.25, +2.50 or +3.25. This shows the strength of reading glasses that you require.
