Vision is vital for learning. Impaired vision will affect performance at school, ability to participate in games and sports and the child's self-confidence. It has been estimated that vision is needed in approximately 80% of learning activities. Regular vision checks are vital from an early age. Nevertheless, a significant proportion of eyesight problems are only discovered when the child starts school. A child who has to wear glasses does not need to feel awkward or different. Johnny Depp, Dr Who, Harry Potter, Elton John and Bill Gates are some of the role models who have helped children to feel OK about wearing glasses. Too much or too little exposure to light can increase the risk of a child developing vision problems. Research has shown that children who spend a couple of hours in outdoor play each day are at less risk of eyesight disorders. However, too much exposure to sun can be harmful. Having a night light in a child's room increases the risk of short sight. A healthy diet provides vital vitamins to maintain the health of the eyes. A good diet, and a healthy lifestyle in general, will help to protect your child from problems such as cataracts and macular degeneration in later years.
