Smooth and accurate eye movements are vital for efficient reading and writing. Without smooth, fine motor eye movements you cannot hold your eyes on important things such as the words when reading. Information cannot flow smoothly through to the brain to be analysed and attention will be poor.
Poor directed eye movements will cause jerkiness when reading, writing and copying and lead to the skipping of letters, number and lines when looking at a page of work. When directed eye movements are poor you may need to move your head more when reading or use a finger to help you hold your position on the page.
