This really hit home for me. Once, long ago, I was night skiing, and my contact lens popped out of my eye. It was a hard lens (do they even make those anymore?) and it was tinted blue. I searched and searched, on my hands and knees. It was cold and windy, but very well lit. After about a half an hour, I actually found the lens. And, I believe, I acted exactly the same way as this guy did.

If you don’t want to watch the whole thing, once he starts searching, jump to about 2:30 for the finding part.
