Itching is commonly associated with allergies; however, given that your complaint is only on one side this is unlikely unless you sleep with the affected side down on your pillow most of the time. Allergic itching can be effectively treated with over-the-counter antihistamine eye drops or pills. Tears often help dilute irritants and may also be effective.

Another common cause of itching along the lid margin is blocked oil glands, or blepharitis. Regular eyelid hygiene with hot packs and baby shampoo can be effective for this type of problem.

If your symptoms do not resolve with these remedies, see your ophthalmologist for an examination to diagnose and treat your specific issue.
