There are no uncomfortable symptoms in the eyes and no need to clean the eyes. If you notice a significant increase in discharge from the eyes or if a foreign body enters the eyes, you usually consider flushing the eyes with saline. Because eye infections can lead to acute conjunctivitis, the conjunctival sac may produce large amounts of discharge and sometimes block vision and cause eye discomfort, so flushing the conjunctival sac with saline can effectively reduce the inflammatory response and relieve symptoms. If a foreign body is accidentally introduced into the eye, it is common to consider flushing with a large amount of saline to expel the foreign body and the accompanying pathogenic bacteria from the eye with the flushing process, which not only reduces the damage to the conjunctiva and cornea from the foreign body, but also reduces the possibility of secondary infection. If you find that your eyes are showing signs of discomfort, choose a hospital eye clinic for conjunctival sac irrigation.
