Why do my eyes itch at night?

Allergies: Do you have allergies? When one has ocular allergies the eyes may get red and irritated, and they usually itch. Itching is the most common symptom of eye allergies. There are several excellent prescription eye drops which can alleviate the itching.

Allergies and drynes: Itching is often a symptom of allergy, although dryness can sometimes make the eyes feel a little itchy, too. An eye exam by a physician can often help make a diagnosis.
