Being blind, is just simply the condition of not having visual perception. Like everything medical, and even today non-medical there is a more ‘advanced’ definition of blindness. This definition in North America is defined as having 20/200 or less in an individual’s best eye after eye correction, such as contact lenses, or glasses. 20/200 means that you would stand 20 ft away from an object and see the same thing as someone with normal eyesight would see from 200ft.
