Answer 2

Answer:

Braille is a system of raised dots that can be read with the fingers by people who are blind or who have low vision. Teachers, parents, and others who are not visually impaired ordinarily read braille with their eyes. Braille is not a language.

Braille allows blind and partially sighted people to learn spelling, grammar and punctuation and gain an understanding of how text is formatted on the page. Individuals learn in different ways – some people may find it easier to take in information via audio while others prefer to read the written word in braille.
