Its a puzzle that was posed over 300 hundred years ago by William Molyneux. Now thanks to modern advances it is possible to restore sight to some people who has been blind from birth, in India patients who underwent eye surgery to restore their vision having never been able to see before were found to be initially unable to distinguish objects but would very quickly develop the ability to do so within the space of a few days,
