Good visual ability allows you read faster, with less effort, understand more of what you read and remember it. You are less tired, so you do not have to put so much effort in. You can train tracking and jumping eye movements; inefficient focussing skills; eye alignment and control improvement; visual perceptual or information processing. You need good bilaterality (both sides of the body together), eye hand coordination, form discrimination, visualisation, memory and directionality. All of which can be trained.
As physiotherapy training is designed for the person concerned and is modified depending on progress, homework has to be used to allow you to make greater progress. Therapy sessions are usually every three weeks and reviews in 4-12 months.
