I suffer from a Traumatic optic neuropathy in one eye. Is there an exercise to practice seeing from 1 eye?

doctors have told that this is a non curable syndrome. i have trouble playing shuttle cock, inserting a thread into needle, driving, playing cricket and doing anything that requires precision distance measurement by eyes.. they say practice makes a man perfect. can some1 suggest exercises that can help my eyes http://bit.ly/nrKJZ8
