In 1809 Lousin Braille invented the method of Braille which helps blind people to read characters by feeling them with fingertips.
In Braille the characters are represented by the dots that are felt with fingertips and to create awareness of the importance of Braille as means of communication, the world observes 'World Braille Day' every year on 4th January. This day was first established by United Nations General Assembly in 2018 and come to in observation in the year 2019.
