Pitched at children aged 5-7, each title discusses the condition, how it affects everyday life and how it can be treated.
There is detailed medical data, information on aspects of everyday life ("Some gardens are specially planted for blind people to enjoy") and lots of positive messages: for example, a blind person can become a train driver; and people in wheelchairs can play rugby or hang glide.
