Are there any other kinds of visual problems that can cause reading or learning problems?
Yes. Although convergence problems are more common, we also see children who have laterality problems. These problems can effect reading, auditory competence, mobility, language, and manual ability, especially writing. Children should develop hemispheric dominance by the time they are six years of age, which is to say a child should be clearly right-sided or left-sided by then. Handedness is the most obvious sign of a child’s laterality. In order to achieve complete neurological organization a child must have complete hemispheric dominance in all areas of function. This means that the child must not only use the same hand consistently but that this hand should match his eyedness, earedness, and leggedness. If a child is right-handed, he should also be right-eyed not only at far point but, what is more important, at near point. For example, if a child is right-sided (right-handed, eared, and legged) but is using his left eye as the dominant eye instead of his right eye, this can cause p
