Allergic Conjunctivitis: Causes, Triggers, and How to Find Relief

When your eyes turn red, itch like crazy, and water nonstop, it’s often not an infection—it’s allergic conjunctivitis, an immune reaction in the eyes triggered by airborne allergens. Also known as eye allergies, it’s one of the most common reasons people visit eye doctors—not because it’s dangerous, but because it’s so annoying.

Some people find that switching to daily disposable contacts or using artificial tears helps wash away allergens.
