French movie star Julie Delpy's parents feared the actress was "a retard" when she was a child - because she kept bumping into things. It took years for the family to realise Delpy had terrible eyesight. She explains, "I don't have a sense of depth, no three dimensional vision. It affects my life a certain way. "All my childhood I was thought a clumsy person. I just didn't see distance, so I would bump into everything. I always thought I was retarded."
