In The Marriage of Heaven and Hell, William Blake says that "If the doors of perception were cleansed everything would appear to man as it is: infinite." In vision, of course, there is a simple connection between optical infinity and perceived visual clarity, at least for distance vision in emmetropes. Contact lens practitioners and refractive surgeons have taken things one step further. By exploiting the brain’s ability to perceptually suppress central vision in one eye when the two eyes are receiving disparate stimuli, they have found that it is often possible to correct presbyopic ametropes using a distance correction for the dominant eye, and a near correction for the non-dominant eye. In this "monovision" situation, patients thus have to suppress the central vision in their non-dominant eye for distance tasks, and in their dominant eye for near tasks.
In essence, monovision is a form of deliberately introduced
