Blepharitis is an inflammation of the eyelids that involves the edges of the eyelids and eyelash hair follicles. Blepharitis is a common and sometimes long-lasting condition that usual affects adults, but also can occur in children.
People with skin conditions such as rosacea, seborrhea, oily skin, dandruff or dry eyes are more likely to get this condition.
Blepharitis can be triggered by bacterial infections or by the eyelid glands making too much oil. This condition is not contagious.
