The color of eyes are genetic and vary from people to people. Generally speaking, people who are born blind doesn't mean they don't have eyes balls. The eye color of someone with blindness is usually White, Grey or Pale. Most blind people have normal looking eyes and remain their original color of eyes when they go blind. Eye color does not change when a person becomes blind. The colors of eyes could only change in case there is a defect in pigmentation and sometimes after trauma when the iris becomes atrophied, which means being dead. Some iris color change is usually noticed with age and also with some medication like anti-glaucoma drugs. In addition, there may be a hazy color of grayish-blue for the eyes of blind people. It also depends on the causes that lead to their blindness, if they were not born blind.
