Acute conjunctivitis is characterized primarily by redness of the eye, which is one of the most important signs of conjunctivitis. The conjunctival surface is largely exposed to the external environment, making it susceptible to irritation and injury. The conjunctival sac provides a suitable temperature and humidity, creating favorable conditions for pathogenic microorganisms to cause infection. Once infected, the eye becomes red. It is essential to maintain good eye hygiene and avoid rubbing the eyes with hands.
