Louis Braille became blind at age 3 in a accident at his dad’s workshop. He meet , Charles Barbier, a former soldier in Napoleon Army at National School of blind, Paris. Barbier shared his invention called "night writing," a code of 12 raised dots invented for Napoleon; who wanted a secret code that could be used at night. It proved to be too complex for soldiers to learn and was rejected by the army
Louis trimmed Barbier's 12 dots into 6 and thus came in Braille language
BTW, Of the 37 million people across the globe who are blind, over 15 million are from India.
What’s worse is 75% of Indian cases are curable, India needs 40,000 optometrists, it has only 8,000, India needs 2.5 lakh donated eyes every year, but could not find enough donors, 30% of donated eyes could not be used, thx to pathetic infrastructure
153 million Indians don’t have access to reading glasses. Only 5% of 2 million blind children in India receive any kind of education.
What’s more pity is our attitude towards physically challenged
