The recovery time for acute conjunctivitis is related to the type of pathogen, the severity of the disease, and the patient’s own condition, but it does not heal on its own. Acute conjunctivitis is usually caused by bacterial and viral infections and manifests as eye irritation symptoms such as photophobia, tearing, conjunctival congestion, eye pain, mild loss of vision, and heavy discharge, etc. It does not heal on its own and needs to be given standardized treatment. Bacterial conjunctivitis can be fully recovered in 5-7 days with antibiotic drops and oral antibiotics; viral conjunctivitis can be recovered in 10-14 days with antiviral eye drops or even intravenous antiviral treatment; allergic conjunctivitis patients need to identify the allergen. Patients with allergic conjunctivitis need to identify the allergen and apply anti-allergic eye drops, and in severe cases, oral anti-allergic drugs, which can be recovered in 3-5 days. Children, elderly and frail patients or those with underlying diseases have a longer course of disease. In addition, patients should pay attention to personal hygiene, keep their eyes locally clean, avoid spicy and irritating foods, and avoid staying up late.
