Blindness, it's a worldwide problem, even though we have some technology to help people be able to see, but some don't have enough money. Braille is the exception to many people not being able to read. Louis Braille was a French educator and inventor of a system of reading and writing for use by the blind or visually impaired. He invented Braille so people could read without being able to see. They would have to memorize and begin to know what they mean. Braille is a system or pattern of raised dots on a sheet of hard paper making your fingers feel the raised dots. The people who used this are talented and are able to read as many books they would please. Braille is used in many different ways, in codes and in books, paper and languages.
