If you have red blood in your eyes, you should go to the hospital to check how it is caused. For example, if it is caused by inflammation, you should take anti-inflammatory treatment. Inflammation can be divided into bacterial, viral, fungal, chlamydial, or allergic. There are many kinds of inflammation, and the drugs are different. When the time comes, if you have confirmed the inflammation, you can use the corresponding anti-inflammatory eyedrops. Sometimes the congestion of the eyes is caused by eyestrain, so we should take a rest, and then click some eyedrops to relieve eyestrain, and then go out to look at the distance. Even looking far can relieve eyestrain. Other times, eye congestion is caused by dry eye disease. Dry eye disease can also be relieved by using artificial tears or eye medicines to lubricate the eyes. Sometimes the red blood in the eyes is caused by eye trauma or wearing contact lenses, which can also lead to congestion in the eyes. If it is caused by trauma, it should recover slowly, and then use anti infection eyedrops. If it is caused by wearing contact lenses, you should stop using contact lenses for a few days, and then wear contact lenses after complete recovery.
