Chapter 30: Blindness and Difficulty Seeing
Difficulty with seeing can be mild, moderate, or severe. When a person sees very little or nothing, we say he is blind. Some children are completely blind; they cannot see anything. However, most blind children can see a little. Some can only see the difference between light and dark or day and night, but cannot see any shapes of things. Others can see shapes of large objects, but none of the details.
Many more children are not blind but do have some problem seeing things clearly. For example, they may see fairly well for most daily activities, but have trouble seeing details. The family may not realize that the child has a seeing problem until they notice she has difficulty threading a needle, finding head lice, or reading letters on the blackboard at school. Often these children can see much better with eyeglasses or a magnifying glass. (Children who are completely blind cannot see at all, even with eyeglasses.)
Some children are born blind. Others become blind during early childhood, or later.
