What is blepharitis?

Blepharitis means “inflammation of the eyelids”, namely the eyelid margins where the eyelashes grow. Natural oils and bacteria build up and form ‘crusty’ material that irritates the surface of the eye. Often blepharitis causes redness of the eyes or eyelids, itching, foreign body sensation and general discomfort. It is caused by an imbalance of oil production and therefore has no cure but treatment is needed for this chronic condition. Lid scrubs, warm compresses and antibiotic drops may all be needed.
