Itchy eyelids are commonly caused by allergies, according to Healthgrades. Other causes of itchy eyelids are infections and lack of sleep. The symptoms that accompany itchy eyelids include eye tearing, eye irritation, face swelling and eye redness.
In addition to general allergies such as dust, animal dander and hay fever, allergic reactions to eye makeup and other personal care products can cause eyelids to itch, claims Healthgrades. Allergies that result in conjunctivitis, which is inflammation of the eye surface, also can lead to itchy eyelids.
Infections such as blepharitis, chalazion and hordeolum cause itchy eyelids, notes Healthgrades. These infections inflame the region around the eyelashes and eyelid margins, which cause the eyelids to itch. The majority of these conditions don't interfere with vision and are not dangerous. In most cases, itchy eyelids heal in a couple of days without any treatment. However, those suffering from itching of the eyelids can use over-the-counter antihistamines and cool compresses to obtain relief.
To prevent eye irritation from escalating, the patient should avoid rubbing or scratching the eyelids. In case of serious symptoms such as breathing difficultly, sudden face and lip swelling and vision loss, emergency medical treatment should be sought immediately, according to Healthgrades.
