Whilst many children with dyslexia or ADD / ADHD have good eye sight according to standard visual acuity tests, there is some evidence to suggest that other aspects of vision which do not get routinely tested may have problems. This includes the visual field or how good you are at seeing things which are in your peripheral vision. If you wish to try out your field of vision, try out this visual field tester.
