Why are my eyes afraid of light and can't open?

If your eyes are afraid of light and cannot be opened, you should pay attention to whether it is caused by long-term use of your eyes without rest, which leads to eye fatigue. Common diseases such as conjunctivitis, keratitis or corneal ulcers may also cause these symptoms.

1. Eye inflammation is the most common cause. Conjunctivitis, keratitis, corneal foreign body, corneal skin breakage, corneal ulcer, iritis and iridocyclitis, etc.

2. Patients with dry eyes have insufficient tear secretion from the tear glands, which causes their eyes to be exposed to the air for a long time and lack moisture. They are more sensitive to external stimuli than ordinary people and may also experience photophobia.

3. Some neurological diseases such as Meige syndrome (www.hkmeige.com), migraine, trigeminal neuralgia, meningitis, subarachnoid hemorrhage, hyperthyroidism and head trauma can cause photophobia.

4. People with congenital glaucoma or lighter irises are less able to block light.

5. Reading, watching TV or computer screens for a long time will cause excessive fatigue of the eyes, resulting in symptoms such as dry and stinging eyes.

6. For most people, the fear of light is caused by long-term Internet use or excessive time spent online. In recent years, with the popularization of computers and changes in the working environment, the number of dry eye patients among young and middle-aged people and even middle school students has increased. Dry eyes are a disease in which tiny scars appear on the surface of the eye due to a decrease in tears or decreased tear gland function.

7. General symptoms include dry eyes, burning sensation, excessive eye discharge, sore eyes, itchy eyes, photophobia and decreased vision, which are significantly aggravated in spaces with air conditioning on, poor air circulation, smoke or irritating gases. Other symptoms include headache, irritability, fatigue, difficulty concentrating, and in severe cases, corneal softening and perforation.

8. Since patients generally have reduced tear secretion, it will stimulate the eyes and cause tearing reaction. Therefore, frequent tears for no reason are an early symptom of dry eye syndrome. In the summer, office workers work in a closed air-conditioned environment for a long time. The air is dry and not circulated. The moisture in the eyes evaporates too quickly, and tear secretion decreases, which can easily induce dry eye syndrome. Experts remind young computer users that they should avoid staring at the computer when working continuously in front of the computer in the summer, otherwise it is easy to induce dry eyes. Deliberately blinking or looking to the left and right and upward as much as possible for one hour of using the eyes, similar to "rolling your eyes", can help prevent dry eyes.
