According to the UN, Braille is a tactile representation of alphabetic and numerical symbols using six dots to represent each letter and number, and even musical, mathematical and scientific symbols.

"Braille (named after its inventor in 19th century France, Louis Braille) is used by blind and partially sighted people to read the same books and periodicals as those printed in a visual font. Use of braille allows the communication of important information to and from individuals who are blind or partially sighted, ensuring competency, independence and equality," informs.

The UN deems that Braille is a means of communication for blind persons, as reflected in article 2 of the Convention on the Rights of Persons with Disabilities and is essential in the context of education, freedom of expression and opinion, and access to information and written communication, as well as for the social inclusion of blind persons, as reflected in articles 21 and 24 of the Convention.

According to World Health Organization, that globally approximately 1.3 billion people live with some form of distance or near vision impairment. People with vision impairment are more likely than those without to experience higher rates of poverty and disadvantage.

The UN reminds that over the years, disability policy developed from elementary care at institutions to education for children with disabilities and rehabilitation for persons who became disabled during adult life. Through education and rehabilitation, persons with disabilities became more active and a driving force in the further development of disability policy.  The efforts have led to heightened awareness of the capabilities of persons with disabilities and floating of initiatives related to their education, rehabilitation, integration and normalization.
