International Blind Day is celebrated every year on November 13 in many countries around the world to draw society's attention to blind people, disseminate information about blind people and their rights.
To ensure that blind people feel fully integrated into society, almost 200 years ago a universal system of raised dot font (Braille) was developed.
Braille is a unique alphabet named after its inventor, Louis Braille. It is a tactile combination of graphical symbols using 6 dots, which allows for the transmission of letters, numbers, musical, mathematical, and scientific signs. Braille is a means of communication for blind people. With it, they can learn, receive information, and exercise their rights to freedom of expression and beliefs.
At the core of Braille is a combination of six dots. Different combinations of these six dots allow for the representation of letters, numbers, punctuation marks, as well as mathematical, chemical, and musical symbols.Forpeople with visual impairments, specially enlarged fonts are used.
