What strange problems will occur to blind people after they regain their vision? ? ?

Ruby was born blind and was unable to see the outside world for the first 52 years of his life.He lived so well in those years that he was often seen cycling around the village with his hand on a friend's shoulder.He also uses the tools in his workplace to make things.But he longed to have the light, and he spent most of his life trying to find a way to see the world. ?
When Ruby was 52 years old, he had a successful corneal transplant.For the first time in his life, he saw the world.Soon he became familiar with everything around him, but he had no sense of perspective, depth, or speed.He thought he could easily lower himself from the hospital window to the ground, even though he was on the fourth floor.When crossing the street, he became very frightened when he saw the passing vehicles, even though he had walked this street all his life when he was blind and knew it well.About two months after the operation, he became very depressed, always staying at home, in the dark, unwilling to go out again. ?

Due to his lack of acquired experience, he had difficulty adapting. ?
