In a house, you wouldn’t lay down the carpeting before the foundation was strong and sturdy. You wouldn’t put up the curtains until the walls were up and the windows installed.
Books Neural Therapy™ looks at the foundation level for causes. If someone notices a vision problem, most people would go first to the optometrist or ophthalmologist. However, a Books Neural Therapist would go back to foundational issues and would therefore check the housing of the eyes (the bony structure that encases the eyes) and the four cranial nerves that address eye movement and function.
If the eye muscles are tighter on one side than the other, it will be impossible for the eyes to track together and reading will be slower. Depth perception could be affected, which would impact the ability to judge distances in sports or while driving a car. These are structural and neurological problems and need to be addressed at those levels. The person may still need eyeglasses. But the eye doctor will be addressing near and far vision, astigmatism, etc., and not the foundational component addressed in Books Neural Therapy.
