What causes blepharitis?
The most common cause of blepharitis is a bacterial infection affecting the base of your eyelashes or the glands in your eyelids.
Other causes include:
- viral infections — such as herpes simplex
- allergies — for example to pollen, eye makeup or eye drops
- skin problems — such as dermatitis, dandruff or rosacea (skin redness)
- blocked oil glands at the edge of the eyelids — this can be caused by seborrheic dermatitis or rosacea
When should I see my doctor?
See your doctor if your symptoms do not improve after a few days of self-care.
Your doctor may take a swab from your eyelid so they can identify the cause of your symptoms and suggest an effective treatment.

How is blepharitis treated?
Your doctor may prescribe medicine to treat blepharitis. There are also things you can do at home to relieve your symptoms.
Medicines
If your doctor suspects an infection, they may prescribe medicines such as:
- antibiotics — ointments or tablets for bacterial blepharitis
- antiviral medicines — for viral blepharitis
- antihistamines — for allergies
- antiparasitic medicine — to kill parasites
They may also recommend lubricating ointments to treat dry eyes, and occasionally corticosteroid ointments, if other medicines don't work.
Self care
Eye hygiene is important. To treat blepharitis at home you can:
- Massage your eyelid towards your nose to help release oil from the glands.
- Clean your eyelids.
- Use a cool compress — for allergic blepharitis.
- Use a warm compress — for all other types of blepharitis.
To clean your eyes:
- Use warm water or diluted baby shampoo. Mix 1 part shampoo with 10 parts water.
- Dip a cloth or cotton bud in this liquid and gently wipe along your eyelid — including the edges of your eyelids and your eyelashes.
You can also ask your pharmacist or doctor about eyelid cleaners.
To apply a warm or cold compress:
- Dip a clean face cloth into very warm or cold water.
- Squeeze the cloth until its damp and hold against your eye for over 3 minutes.
You can do this once or twice a day.
Always talk to your doctor to find the best treatment plan for you.
