What is blepharitis?
Blepharitis is a chronic inflammation of the eyelids, often along the lash line. It causes redness, itching, irritation, and especially dry eyes, which can significantly reduce eye comfort.
Common causes
- Bacterial overgrowth on the edge of the eyelids
- Meibomian gland dysfunction (responsible for the lipid layer of tears)
- Skin conditions such as seborrheic dermatitis or rosacea
Main symptoms
- Red and irritated eyelids
- A burning and itching sensation
- Dry or watery eyes (both are common)
- Crusts or dandruff at the base of the eyelashes
- Light sensitivity
Treatment and advice
- Eyelid hygiene: daily cleansing with warm compresses to loosen sebum and remove crusts
- Ocular lubricants / artificial tears: essential for relieving dryness and protecting the cornea
- Topical antibiotics: only if the bacterial inflammation is severe
- Management of associated conditions: dermatitis, rosacea, or Meibomian gland dysfunction
Regular follow-up with an ophthalmologist is crucial to prevent complications, including infections or worsening of dry eye.
