There are a lot of red blood in the eyes.

The conjunctiva is rich in blood vessels. Red blood near the fornix is called conjunctival congestion. Congestion near the limbus is called ciliary congestion. Many eye diseases cause red blood. If conjunctival congestion is shown, it is initially considered to be related to conjunctivitis. It may be infectious conjunctivitis caused by pathogenic microorganism infection, or conjunctivitis caused by other external physical and chemical factors, such as light or chemical stimulation of conjunctiva. If the white eye shows red blood, it may be caused by bulbous conjunctivitis or foreign body or trichiasis. If red blood is distributed around the cornea, it may be related to corneal foreign body, keratitis and intraocular diseases, such as uveitis and endophthalmitis. Therefore, if the eye shows red blood, first of all, we should pay attention to developing good eye habits, pay attention to hand hygiene, ensure adequate sleep, and reduce the stimulation of working environment, sand and smoke. If the symptoms are still obvious, it is recommended to go to the hospital eye clinic in time.
