What should I do if water gets into my eyes while swimming, causing blurry vision?

Blurred vision after water enters the eyes while swimming should be treated based on the specific underlying cause. Possible causes include acute catarrhal conjunctivitis, epidemic keratoconjunctivitis, and allergic conjunctivitis.

1. Acute Catarrhal Conjunctivitis

If symptoms are caused by acute catarrhal conjunctivitis, it is recommended to use anti-infective medications such as levofloxacin eye drops or ciprofloxacin eye drops under medical supervision. If necessary, oral antibiotics such as azithromycin capsules or rifampicin capsules may be prescribed by a doctor to improve symptoms.

2. Epidemic Keratoconjunctivitis

If symptoms result from epidemic keratoconjunctivitis with bacterial co-infection, antibiotic eye drops and interferon eye drops may be alternately used under medical guidance. Commonly used medications include tobramycin eye drops, norfloxacin eye drops, and recombinant human interferon α2b eye drops. When corneal symptoms predominate, corticosteroid eye drops such as tobramycin-dexamethasone eye drops or fluorometholone eye drops may be prescribed by a physician.

3. Allergic Conjunctivitis

If symptoms are due to allergic conjunctivitis, mild discomfort can be relieved with cold compresses. For more severe symptoms, lubricating eye drops such as sodium hyaluronate eye drops or polyvinyl alcohol eye drops are recommended under medical supervision. Alternatively, oral antihistamines such as diphenhydramine hydrochloride tablets or cetirizine hydrochloride tablets may be prescribed by a doctor for treatment.
