Symptoms and causes Dry eye may cause burning, grittiness, redness, watering, light sensitivity and fluctuating vision. Common contributors include screen use, air conditioning, contact lenses, eyelid-gland dysfunction, ageing, hormonal change and certain medicines.
Diagnosis Assessment may include tear-film examination, eyelid and meibomian-gland evaluation, staining of the eye surface and review of medical conditions and medicines.
Treatment Treatment is matched to the cause and may include preservative-free artificial tears, warm compresses, lid hygiene, environmental changes and prescribed anti-inflammatory drops. Selected patients may benefit from punctal plugs or procedures that improve eyelid-gland function.
When to seek care Persistent pain, marked redness, light sensitivity, discharge or reduced vision requires prompt examination because these symptoms may indicate more than simple dryness.
