Visual Acuity. Test visual acuity for each eye separately (by covering one eye at a time), using an eye chart.

Color Vision. Test each eye separately for ability to distinguish colors. Test for red desaturation, a sign of subtle asymmetry in optic nerve function (as seen, for example, in optic neuritis described in KCC 11.4), by asking the patient to cover each eye alternately while looking at a red object and to report any relative dullness of the color as viewed through either eye.
