What causes children's eyes to be afraid of light?

Many people do not take photophobia seriously. Many people are afraid of strong light, but some people are completely photophobic, which is an abnormality. Many people want to know why children are afraid of light. In addition to eye diseases, this may also be due to problems with the child's optic nerve development.

1. Eye inflammation can also cause photophobia, including conjunctivitis, keratitis, etc. Photophobia caused by inflammation is often accompanied by symptoms such as red eyes, eye pain, tearing, increased secretions, and even visual impairment. Some sudden fear of light may be caused by strong radiation from the sun, ultraviolet light, etc., which is called photoelectric conjunctivitis. These symptoms require prompt medical attention. Delaying treatment can lead to worsening of the condition and, in severe cases, affect vision.

2. Children's optic nerves have not yet fully developed and are still very immature, so they are sensitive to light. Most people will feel photophobia and discomfort when they are under the sun or exposed to strong light. The normal reaction is to squint the eyes or use other items to help block the sunlight to reduce eye discomfort, but some people will feel uncomfortable even under normal light intensity. We can say that these people have photophobia.

3. Some non-inflammatory eye diseases can also cause photophobia, such as albinism, aniridia, and total blindness caused by autologous inheritance. There is currently no medical cure for photophobia caused by this type of disease, so the only treatment is passive. For example, wear sunglasses or hats when going out, and avoid too strong indoor light.

4. Some systemic diseases can also cause photophobia, such as migraine, trigeminal neuralgia, meningitis, subarachnoid hemorrhage, hyperthyroidism and head trauma. People with congenital glaucoma or lighter irises are less able to block light. The photophobia caused by these diseases can be relieved and improved to a considerable extent after surgery or drug treatment.
