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.
