You're shoving a foreign object into your eye. Your eye isn't used to it, but it should get used to it eventually.
Put a towel over the sink. If you drop it somewhere and can't see it, use a flashlight to find it.
Blink more. See if that helps. If not, you may have your contacts in incorrectly.
I'm assuming you have soft contacts?
As for my story, I can't see anything without corrective eyeware. I can barely see that there's text on the moniter about 18 inches away from my face.
