Strabismus

"Strabismus, more commonly known as crossed-eyes or wall-eyed, is a vision condition in which a person can not align both eyes simultaneously under normal conditions. One or both of the eyes may turn in, out, up or down. An eye turn may be constant (when the eye turns all of the time) or intermittent (turning only some of the time, such as, under stressful situations or when ill). " (www.strabismus.org)

When researchers do research into strabismus in primates they induce strabismus by making the primates wear goggles. I went to a research presentation the other day about this topic. One word to the wise strabismus researcher, if you put pictures like this is your presentation, do not get offended when people laugh!
