A focus light is shown for use with an ophthalmologic microscope. A patient is directed to gaze at this focus light during surgery keeping his or her line of sight offset by about 18° from the illuminating light source, thus having the effect of directing a significant portion of the light source to the optic nerve instead of the macula to reduce photophobia and phototoxicity. A secondary focus light is also shown for temporarily redirecting the patient's gaze for certain incisions.
