How to Focus the vision screener
Monocular Mode
In monocular mode, you will be given the option to choose which eye to screen. This should be
attempted when binocular screening does not capture the subjects’ pupils.
1. Touch the side of the screen that corresponds with the eye you would like to screen. (OD =
subjects right eye; OS = subjects left eye).
2. When complete, you can repeat the process with the other eye by choosing Monocular from the
Results Menu.
