Most eye infections are classified according to their cause, and are generally classified as either bacterial or viral infections, with these two types of infections being the most common. Bacterial infections mainly cause bacterial keratitis and bacterial conjunctivitis, of which bacterial conjunctivitis is the most common and is often referred to as pink eye, usually caused by improper eye hygiene and requires the use of anti-inflammatory drugs. The signs of bacterial infection are mainly yellow eye droppings, especially in the morning when there is a large amount of pus-like eye droppings that stick to the eyelids and prevent the opening of the eyes, and during the day there is also a large amount of eye droppings that stick to the eyelashes, which is a typical sign of bacterial infection. The other type of infection is viral infection, which is caused by a decrease in body resistance and immunity, in which white eye stool is the main cause, and there is a certain amount of tearing and foreign body sensation, and the white of the eye is also more serious congestion. This condition usually requires the use of antiviral drugs to relieve, and most of them have a long course, usually 3-4 weeks to get better.
