Colour Blindness

Colour-blindness is the inability to distinguish the differences between certain colours. The first scientific paper about colour blindness was written by John Dalton in 1793 entitled ‘Extraordinary facts relating to the vision of colours’. About 8% of all men and 0.5% of all women are colour-blind; However, women are carriers. Colour blindness is not deadly but it comes with many issues such as difficulty in school, problems with food, confusing medications, and trouble identifying safety signs.
