Causes

The exact cause of blepharitis isn't clear. In some cases, it can spread to another person. It might be associated with one or more of the following:

• Seborrheic dermatitis — dandruff of the scalp and eyebrows
• Infection
• Clogged or malfunctioning oil glands in your eyelids
• Rosacea — a skin condition characterized by facial redness
• Allergies, including allergic reactions to eye medications, contact lens solutions or eye makeup
• Eyelash mites or lice
