Can we cure blindness?

Color blindness cure?

• My father has had color blindness since birth and I feel really bad that he can't experience the true colors of the world. Is there any cure or anything he can do to improve his vision?

• Answer:

  I know that this is a sad topic for you.. but I am not sorry to say, please use common sense. No, there is no cure or he would not be in this predicament. At the same time... I must ask, does he have good vision? (except for color loss...) Because animals that are considered color blind usually have good vision... it is thought that the more "rods" in the eyes contribute to better vision, but less sense of color... so is colorblindness neural or optical? Or, then again, there is another type in which the brain (or eye) can distinguish color well, but can still see it... (such as the disability to tell red and green apart) message me if you know more about this...
