You may have tiny glands that are clogged on your eye's inner leadge causing them to touch the eye making it feel like there is something in there. When your contacts are in it is blocking that sensation. These clogged glands are not dangerous, but it is best to see a doctor and metion this to him. There is medicine to help. I have this problem as well good luck, it's more of a neusence then anything. This happened to me last year and I found out from another eye doctor that my doctor from home prescribed me the wrong base curve for my contacts, which resulted in my getting Keratitis aka an inflammation of the cornea.

Can safety glasses affect your vision if you where contacts?
They could. Generally, nonprescription safety glasses have plano lenses, which mean there is no prescription to effect your vision. But, most of them have a general optical center (the part of the lens with the clearest vision). If you went to an eye doctor and got a safety pair of glasses they would measure this optical center to make sure you are getting the clearest vision possible. Glasses with a general optical center do not account for people who's eyes are close or far set. If you were not looking through the optical center it is possible that you would notice some distortion in your vision (nothing to extreme, just not quite clear).
