The exact cause of blepharitis isn't clear. Factors associated with the development of blepharitis include:
- Seborrheic dermatitis — dandruff of the scalp and eyebrows
- A bacterial infection
- Malfunctioning oil glands in your eyelid
- 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
- Certain medication — the severe acne medication isotretinoin (Amnesteem, Claravis, Sotret) can lead to an increase in bacteria on the eyelids and can affect tear production
Blepharitis may be caused by a combination of factors.
