Causes

By Mayo Clinic staff

Blepharitis occurs when tiny oil glands located near the base of the eyelashes malfunction. Blepharitis is often a chronic condition, meaning that it may require long-term care.

Diseases and conditions that can cause 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

Blepharitis may be caused by a combination of factors.
