Blepharitis is an inflammation of the eyelids. The membrane covering the inside of the eyelid and the white of the eye may also become inflamed. Blepharitis can be caused by bacteria (germs) on the eyelids or on the skin around the eyes. Dandruff or oily skin can also cause blepharitis. Wearing contact lenses or makeup can make the symptoms worse. Blepharitis can’t always be cured. But it can be controlled.

Oil and bacteria coat the eyelids near the base of the eyelashes. You may then have:
Redness of the eyelids
Swelling and tenderness of the eyelids
Itching around the eyelashes
Greasy flakes or scales around the eyelashes
Hard crusts at the base of the eyelashes. These crusts may cause the eyelashes to fall out.
Flakes or crusts can form during the night. If this happens, it may be hard for you to open your eyes in the morning. If blepharitis is not treated promptly, it can lead to a cyst (an inflammation of an oil gland on the eyelid) or a stye (an infection at the base of an eyelash).
