Denzel is not alone . In fact , nine out of ten blind children in America 's public schools do not know and are not being taught how to read and write using Braille . But reading Braille , especially when learned at an early age , is just as effective as reading print . Braille is also the only system that allows blind people to write and to read what they have written with speed and efficiency . That is why the National Federation of the Blind wants to make sure that young people like Denzel graduate from high school with the ability to read and write , and that every blind child in America and every adult losing vision is given the opportunity to learn Braille . But blind Americans need your help to address the crisis in Braille literacy .
