Is there a relationship between eye-coordination problems and poor reading?
At about four months the baby has learned to fuse the images from the two eyes into one three dimentional image. Eye-coordination continues to develop as the child learn to play progressively more and more demanding games. If a child have not quite developed propoer eye-coordination then reading becomes very difficult. For example, if the eyes has a tendency to deviate outwards, the medical term for this is exophoria. In order to read, even with minor diversion, massive energy and effort is needed to keep the eyes pointing at the book. If the eyes fuse the image beyond the page the child will experience eye strain and fatigue very quickly.
