Symptoms to watch for
- Redness in the white of the eye
- Watery or thick discharge

- Eyelids stuck together in the morning
- Itching (allergic type)

- Iritis — deep pain, photophobia
- Corneal ulcer — needs urgent ophthalmology
- Dry eye syndrome
How it's diagnosed

Treatment
Viral: cool compresses, artificial tears, resolves in 1–2 weeks. Bacterial: erythromycin ointment or polymyxin/trimethoprim drops. Allergic: antihistamine drops (olopatadine).
