Surfer's eye or Pterygium is an eye problem in which fibrous tissue grows over the surface of the eye. To treat this condition, surgeons often cut out the tissue with scissors. But one adventurous surfer in Hawaii chose to let the force of water take care of his eye, by dipping his head into the rushing water while surfing a 30-foot (10 meters) wave, according to a report of his case published in 2014 in the journal BMJ Case Reports. Apparently, the blunt force of water ripped off the irritating fibrous tissue, but doctors said the man was lucky the water didn't damage his eye.
