These skills involve moving, focusing and teaming the eyes so they may function efficiently. Vision skills include several components.
Fixation is the ability to direct and maintain steady, central visual attention on a target.
This basic skill is developed in infancy and refined through the early years. Through the toddler years the individual refines this movement system by learning to use eye muscles to replace head movement - an achievement important in visual readiness for school. Eventually vision becomes the dominate sense. Accommodation is another component skill involving focusing the light entering the eyes. This combined lens neuro-muscular system is a network integrating the eyes and the brain.
