Conjunctivitis is usually caused by pathogenic microbial infections or allergic reactions, and it is possible for patients with milder symptoms to heal on their own with rest and conditioning. For patients with conjunctivitis caused by less virulent bacteria or viruses, the inflammation is relatively mild and can be self-healing if the eye habits are corrected in time, eye hygiene is ensured, reasonable rest is taken, and more water is consumed. For some patients with conjunctivitis caused by dry eye, usually due to improper eye use, lack of sleep and other factors, the effect of self-healing can also be achieved without medication after avoiding prolonged eye use and proper rest; 3, for patients with more serious infection or allergic conjunctivitis, relying solely on self-healing is unable to achieve a cure, and may even lead to more serious eye redness, eye pain, photophobia and other eye discomfort symptoms, requiring the use of antibacterial, antiviral eye drops or ointment under the guidance of a doctor. Patients with this condition should avoid prolonged use of antibacterial and antiviral eye drops or ointments. Patients should also be careful to avoid prolonged eye use, frequent use of contacts and contact lenses, and the use of medications to prevent the discomfort of conjunctivitis from worsening.
