Color blind vision test. To do?

Hello, colour blindness is generally a hereditary conditions passed on from previous generations so people in this condition have problem differentiating between red and green in dim light or problem differentiating between blue from yellow. So first enquire about anybody in your family suffering from it, if that's the case then its a hereditary condition and unfortunately there is no permanent treatment for that but there are contact lenses and glasses which helps to differentiate between similar colour that might be helpful. If its a acquired condition which might have happened by exposure to certain drugs or some other underlying condition, stopping of such things will be helpful in treating this.
