Hi .Double vision usually comes from a stroke in the brainstem. With double vision, a person loses depth perception, and may get confused by what he or she sees. The quick fix for this is to patch one eye, but that doesn’t fix the problem. But treatment requires accurate diagnosis, because there are many therapeutic techniques that need to be considered. Does the eye turn out because of damage to a nerve that controls one of the six muscles in each eye? The location and cause of double vision can determine the type of treatment. Best regards
