Red eyes

It’s probably allergies, aka allergic conjunctivitis—a reaction to pollen, pet dander, or something else in your environment. Get away from the trigger if possible, whether it’s a fluffy cat, a dusty attic or a park full of ragweed. Then take an oral antihistamine to halt the immune system reaction, says Tim Mainardi, MD, an allergist with New York-Presbyterian/Weill Cornell Medicine in New York City.
