DEAR DOCTOR K: I have allergies, and my eyes are affected the most. They're puffy, red and itchy. What can I do?
DEAR READER: Pollens, animal dander, dust mites and mold: The same allergens that cause sneezing and an itchy nose and throat can trigger allergy symptoms that affect your eyes, too. If your eyes are red and itchy, you may also have tearing, mucous discharge and swelling of your conjunctiva (the inside of your eyelid). This constellation of symptoms is known as allergic conjunctivitis. It can be uncomfortable, but it is not a threat to vision.
