Two Good Eyes and Cognitive Ability

In Greek mythology, cyclopes were one-eyed creatures who possessed enormous strength, but not too much wit---something that could perhaps be attributed to their anatomy. After all, human beings have two eyes for a very good reason.

Having two eyes enables depth perception. One eye can compensate for the errors made by the other eye, with both eyes mutually supporting each other in conjuring images. Each eye takes slightly different snapshots of the world, leaving it up to the brain to process the images and come up with a concrete image.

Thus, when the ability of one or both eyes is diminished for one reason or another, a person’s cognitive abilities may also be affected. This is true in both children and adults. In some cases, behavioral or cognitive problems observed in a child are the result of undetected visual impairment, which the child may have difficulty coping with.

For this reason, good eye care has to be observed at all times. Regular eye check-ups, especially among children, is very important, as these will help detect potential problems at their earliest stages. Likewise, everyone must be on alert about any optical concerns, and go to an eye doctor when symptoms, such as blurry vision and headaches, arise.
