Red eyes and yellow eye droppings are usually considered bacterial infections, especially when there is a lot of yellow eye droppings that stick to the eyelids in the morning and prevent the opening of the eyes, or when there is a lot of eye droppings that stick to the eyelashes during the day and affect the ability to see. Bacterial conjunctivitis is usually caused by bacterial infection, which may be bacterial conjunctivitis or bacterial dacryocystitis, while the congestion in the white of the eye is more obvious in bacterial conjunctivitis and the congestion in the eye is not so obvious in dacryocystitis, but it is accompanied by tearing. However, both conjunctivitis and dacryocystitis are caused by bacterial infections, so usually antibacterial treatment is needed, using levofloxacin solution or tobramycin solution for anti-inflammatory treatment, and there will be significant improvement after 3-5 days.
