If the eyes are too congested, if it is caused by staying up late or using too many eyes, you can consider some anti-fatigue eye drops for treatment, such as aescin eye drops, pay attention to eye hot compress, rest your eyes and ensure sleep. If patients need to improve the appearance of red eye in the short term, eye drops with vasoconstrictive effect, such as nafenwei eye drops, can be properly considered, but not for a long time. Symptoms of red blood in the eyes, such as pain and photophobia, may be caused by local infection. Eye examination should be carried out as soon as possible, and eye drops should not be used on their own. For example, bacterial infection requires antibiotic eye drops, tobramycin eye drops or ofloxacin eye drops are broad-spectrum antibiotics and have a wide range of applications. Virus infection requires antiviral eye drops, such as acyclovir eye drops.
