It is sometimes expedient to display a reduced number of letters on each row as shown below:



To display one letter on each row, press the I key on the keyboard or mouse once.


In LogMAR mode, pressing the I key again displays two letters, then 3 letters until all five are shown again. Pressing Esc restores the chart to to 5 letters/row.


In Snellen mode pressing the I key a second time displays the complete chart.


I is not available in Single Letter mode for obvious reasons.

Mouse
