If you can't see the hair or eyelash, it's possible that it is already out and what you're feeling is simply the irritation. You don't indicate how long this has persisted. If it has been bothering you for a few days and doesn't seem to be going away, or if you can see the item in your eye and can't dislodge it, a trip to your ophthalmologist is in order. It should be a relatively simple matter for your ophthalmologist to see what' s going on and to treat you.
