Santa Claus would be nothing without his faithful herd of reindeer, who we all know are Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen, and Rudolph. All of these reindeer are special, but Rudolph with his red nose always stands out as the leader. One thing all of Santa's reindeer should have are not one, not zero, but two whole eyes. Eyes are kind of important for reindeer who are expected to fly around the globe.
The creative person who designed these reindeer ornaments decided that reindeer must not need eyes. Eyeless reindeer would definitely make delivering presents a tad more challenging.
