Sudden congestion of the eyes after waking up in the morning is usually a sign of infection, which may be caused by bacterial or viral infection of the conjunctiva. In this case, the choice of medication should be based on the specific symptoms. If the conjunctival congestion is caused by a bacterial infection, it is usually accompanied by a large amount of purulent discharge. In this case, antibiotic eye drops are needed to control the local inflammation, such as levofloxacin hydrochloride eye drops and tobramycin eye drops. If the inflammation of the conjunctiva is caused by a viral infection, it is usually accompanied by aqueous discharge and can be treated with antiviral medications, such as ribavirin eye drops or ganciclovir eye gel. Only with the right choice of medication can the disease return to normal quickly. Of course, there is another situation is the performance of eye fatigue, generally after reasonable rest, can soon return to normal, and eye fatigue caused by conjunctival congestion, is no eye discharge.
