You guys calling the original guy an idiot are all wrong. I'm a huge horse racing fan, and racehorses wear blinkers. A carriage-pulling horse, or a jumper, wears blinders, but the hoods that some racehorses wear are indeed blinkers, which is where the term comes from.
One of the most famous racehorses of all time, Secretariat, wore blinkers in all of his races.
