What is the cause of eye pain?

1. Eye diseases

The most common disease causing eye pain is inflammatory stimulation. Since our eyes are often open, when the body's immunity decreases, external bacteria or viruses can easily enter our eyes, causing eye inflammation and pain. Glaucoma caused by increased intraocular pressure can also cause severe eye pain. In addition, when an eye tumor presses on the eyeball, eye pain will also occur, and this pain is often persistent.

2. Eye Trauma

Although the eyeballs are protected by eyelids, we have to keep our eyes open to see things during the day. Therefore, when danger strikes, the eyes are very likely to be the first to be hit. When an eye is injured, there is usually severe pain in the eye, accompanied by bleeding, blurred vision, or protective closure of the eye.

3. Foreign body stimulation

The sensory system of the eyes is very sensitive. As the saying goes, "You can't tolerate any sand in your eyes," this describes the eyes' low tolerance to foreign objects.

4. Nervous System Diseases

The sensation of the eye is innervated by the ophthalmic branch of the trigeminal nerve (ophthalmic nerve). Therefore, when trigeminal neuralgia occurs, it is also accompanied by eye pain.

5. Drug poisoning

The eyes are rich in blood vessels and have an adequate blood supply. When some drugs are used in excess and lead to poisoning, it is very easy to cause eye discomfort and even become the earliest sign of drug poisoning. Aminopyrine is a commonly used antipyretic drug. When it is overdose, it will cause binocular vision impairment, severe eye pain, red and swollen eyelids, difficulty closing the eyelids, small red drug rashes on the skin; conjunctival congestion, herpetic conjunctivitis; corneal infiltration and turbidity, corneal epithelial detachment in the form of small bubbles; dilated pupils, and optic nerve atrophy can be seen in the fundus.
