To diagnose your eye allergies (allergic conjunctivitis), your eye care professional will ask about your symptoms and when they occur. Most people with eye allergies complain of itchy, watery, red eyes.
A careful eye exam is important in making the diagnosis because some other disorders can cause red eye. Your eye care professional will check your eye for swelling of the blood vessels, conjunctiva, and eyelid. Some people with severe eye allergies may have large, bumpy formations under their eyelid. A physical examination and laboratory tests are also needed to confirm the diagnosis of eye allergy.
