If you are not sure whether your symptoms fit blepharitis, start here. This hub pulls together the most useful symptom and diagnosis guides so you can compare patterns and decide what to read next.

Common blepharitis symptoms

  • Gritty, burning, or tired eyes.
  • Crusting or flakes at the lash base on waking.
  • Red or thickened lid margins.
  • Symptoms that fluctuate with screen use or wind.

Patterns that point to blepharitis

Blepharitis often starts at the lid margin, where the lashes grow. Many people notice morning crusting, irritation that improves after cleaning, and recurrent styes or chalazia.

Evidence-led guidance, written for patients.
Expand any question to see the full answer.
What can be mistaken for blepharitis?
Dry eye, allergic or infective conjunctivitis, styes/chalazia, contact dermatitis or eczema, ocular rosacea, and keratitis can look similar. A clinician can check your lid margins and tear film to confirm.
Why do I only have blepharitis in one eye?
Blepharitis usually affects both eyes, but one side can feel worse. Persistent one-sided symptoms should be checked to rule out other causes.
What type of doctor should I see for blepharitis?
In the UK, start with a pharmacist or optometrist for advice on hygiene and products. See a GP if symptoms persist or you need prescriptions, and an ophthalmologist if referral is needed.
Can an optometrist see blepharitis?
Yes. Optometrists routinely assess lid margins and tear film and can advise on care or referral.
When should I seek urgent help?
Seek same-day advice if you have severe eye pain, sudden vision changes, marked light sensitivity, significant swelling, or recent eye injury.
