Eye symptoms of tearing, redness and itch frequently occur in patients with allergic rhinitis or hayfever. The purpose of this study is to learn whether placing allergen (the substance that causes allergies) in the nose several days in a row will cause an increase in eye symptoms and whether receiving a nasal steroid spray will prevent these eye symptoms.
