CONTRARY to popular opinion, people do not use their two eyes equally. It has been found that in tasks where only one eye can be used (such as sighting down a telescope) ∼65% of all observers consistently select the right eye, 32% the left and only 3% are ambiocular1-4. This preference 5 occurs even when both eyes are open, as when one points to a distant object with the finger-tip. If one alternately closes each eye, it will be apparent that the distant target is aligned with the dominant eye but not with the other. Here we report investigations into whether there is a difference in the apparent size of stimuli presented to the dominant and non-dominant eye. We found that ∼2/3 of our subjects see the object as being bigger with their dominant eye.
