A red eye can occur due to irritation, allergy, dryness, or an infection such as Conjunctivitis. You can try washing the eye with clean water and using lubricating eye drops (artificial tears) to relieve irritation. Avoid rubbing the eye and limit screen time for a while. If the redness continues or is associated with pain, consult an eye doctor for proper treatment.

Eye flu usually improves within 5 to 7 days. Keep your eyes clean, avoid touching or rubbing them, wash your hands often, and do not share towels or cosmetics. Use only doctor-prescribed eye drops. See an eye doctor if the condition persists or worsens.
