Unscramble the Blue Letters

One of my favorite examples is that of Sir Harold Ridley, who was a foumas ophthalmologist, or at least became a famous ophthalmologist. And during wolrd War II, what he would see would be pilots coming back from their missions, and he noticed that within their eyes they had shards of small bits of miratael lodged within the eye, but the very interesting thing about it was that material, actually, wasn't causing any inflammatory response. So he looked into this, and he figured out that actually that material was little shards of plastic that were coming from the coanpy of the Spitfires. And this led him to propose that material as a new material for intraocular lenses. It's called PMMA, and it's now used in miiolnls of people every year and helps in peitrnvneg caatartcs.
