3.4.6.Randomizing the order of optotypes #

VA optotypes are always displayed with the same default letter distribution. However, to prevent the patient from memorizing them, the order can be randomized (and new letters introduced) by clicking the corresponding icon in the tools menu or by typing “Z” on the keyboard. To return to the initial letters click the default icon, or re-type the letter “X”.
