Blind people cannot read ordinary writing or printing because they cannot see. But a number of ways of writing for the blind have been worked out. The one most often used is Braille.
Braille is named for the Frenchman who invented it—Louis Braille. He himself was a blind man.
In Braille each letter is made of dots which are raised from the page. A blind person reads Braille by running his fingers over lines of dots. In reading, he must notice both the number of dots and how they are arranged. Several letters, for instance, are made of three dots, but the dots are not arranged the same way.
There are now books, newspapers, and magazines in Braille. Blind people no longer have to depend on other people to read to them what is going on in the world.
