      Their eyesight would not develop. Eyes need to be stimulated to grow and develop properly.
      In fact there is a condition that affects people who have normal eyesight but that work in dark environments for a long time. Like miners used to in this country many years ago. They lose the ability to keep their eyes still while they look at something and their eyes wobble, its called nystagmus.
