I've been told by an ophthalmologist, that I have 'independent vision' : I cannot co-ordinate both eyes simultaneously, but use either eye, at any one time. Is this common?

Vision impairment has traditionally been associated with a problem with the eyes. There are a number of students with disabilities, however, who have vision loss as a result of disturbance to the posterior visual pathways and/or the visual cortex which deal with the processing and integration of visual information.This is known as cortical vision impairment. These childrenís eyes may appear normal. There is normal pupillary response and no nystagmus yet the child appears to be blind. Vision may appear intermittent. The children are usually attracted to bright shiny moving objects. They will frequently use one sense at a time eg they may look at an object but when they touch it they look away and move around the environment with out bumping into anything. Cortical vision impairment can be described as a condition in which the vision is more severely reduced than ophthalmological findings indicate.

It's not extremely common, however not uncommon. It's actually called an alternating tropia meaning that both eyes develop normally except one eye is really only "focusing" / paying attention (pointing the right way) at one time, and because they switch off as to witch is paying attention no problems occur. Its when the "tropia" is constant that it will become a problem. The guy above didn't answer anything at all, don't pay attention to their reply.
