Part of our success as a species of hunter-gatherers is due to our evolutionary dependence on vision to survive. Of all the integrated systems within the body vision is arguably the most complex. It is not just the connection between the sensory input from a single eye to almost every other part of the brain, but the fact that the two eyes work together to provide a cyclopean view of the world which we largely take for granted. Research is showing that the ability to judge depth and the position of objects is related to eye dominance. The role of the dominant eye is to judge the position of an object in space. The role of the non-dominant eye is to judge depth to be able to anticipate the arrival of an event, be it a car crash or a baseball. As a result of it, role in survival the visual system makes a disproportionately large energy demand on the brain. In recent times information technology has pushed vision well beyond its design capability and the brain is desperately trying to resist this anomaly. This is creating dietary distortions, associated autoimmune processes and immune deficiencies. As a result we are seeing an epidemic of ametropias including myopia, and acquired conditions like obesity, Type II diabetes and psychological morbidity. In this talk, the presenter will describe the path from Cro-Magnonman at the peak of human physiological development totodayâ??s relatively sick society, from a visual point of view.
