Photophobia is an increased sensitivity and aversion to light.

While the term means fear of light, it is not a phobia. It is an eye problem caused due to medical conditions or medicines. 

As per AAO, over 80% of people with migraine may have Photophobia.

It may also affect your nervous system function. In the case of eye trauma, it may only affect one eye.

Photophobia(Light sensitivity)  can have several different causes. A few of them are temporary, while others may indicate a medical problem.

In this article, you will learn more about the different causes of this condition. <\/p>\n\n\n

Photophobia Causes<\/h2>\n\n\n

Sensitivity to bright light (Photophobia) can develop due to many reasons. These could include ophthalmic or non-ophthalmic conditions.

Some conditions that cause Photophobia are related to the eye, while others affect how the body detects pain.

Eye conditions, such as dilated pupils or light-colored eyes, actually allow too much light into the eyes, which is inherently unpleasant.<\/p>\n\n\n

\nThe trigeminal nerve, which controls sensation in the face and eyes, alleviates some of the discomfort associated with Photophobia.<\/div><\/div>\n\n\n\n

Check with your doctor for the real underlying cause. Your treatment may depend on it.

Here are some causes of Photophobia:<\/p>\n\n\n

Migraine<\/h3>\n\n\n

Migraines cause photophobia<\/a> as a common symptom.

Various factors, including hormonal changes, foods, stress, and the environment, can trigger migraine.\u00a0

In addition to throbbing in one area of the head, additional symptoms include nausea and vomiting.

It is estimated that more than 10% of the global population<\/a> suffers from migraine.\u00a0

Tension headaches, another form of headache, may also cause Photophobia.<\/p>\n\n\n

Brain conditions<\/h2>\n\n\n

Here are a few brain conditions that may cause you to experience Photophobia:<\/p>\n\n\n

Meningitis<\/h3>\n\n\n

This condition is an inflammation of the brain and spinal cord. An infection generally causes it.

The infection can be viral, bacterial, or fungal.

Light sensitivity from Meningitis<\/a> signals a dislike of bright lights.

Secondo un study<\/a>, Photophobia was prevalent in around 80% of children with bacterial Meningitis.<\/p>\n\n\n

Encephalitis<\/h3>\n\n\n

Encephalitis occurs when your brain is inflamed from a viral infection or other cause. 

It can also occur when the immune system mistakenly attacks brain tissue in response to a previous infection.

Most individuals with mild Encephalitis recover entirely. However, Encephalitis can be fatal and extremely serious. 

A 2020 study<\/a> around Encephalitis found that nearly 10 percent of hospitalized patients died.

Photophobia is a symptom of this brain<\/a> condition. Check with your doctor, as early diagnosis can stop it from getting severe.<\/p>\n\n\n

Subarachnoid hemorrhage<\/h3>\n\n\n

A subarachnoid hemorrhage is bleeding in the space between the brain and the surrounding membrane. 

The primary symptom is a sudden, severe headache. Some people describe it as the worst headache they have ever felt.

Other symptoms, such as nausea, vomiting, and Photophobia, often accompany<\/a> the headache.<\/p>\n\n\n

Pituitary tumors<\/h3>\n\n\n

A pituitary tumor is an abnormal growth in the pituitary gland. 

The pituitary is a small gland in the brain. It is located behind the back of the nose.

Though rare, there are reports<\/a> of increased light sensitivity due to compressing chiasm lesions.<\/p>\n\n\n

Eye conditions<\/h2>\n\n\n

Photophobia is also common in many conditions that affect the eyes. These include:<\/p>\n\n\n

Scleritis<\/h3>\n\n\n

Scleritis<\/a> happens when the white part of your eye becomes inflamed. It can cause Photophobia as a symptom.

Other symptoms of Scleritis include eye pain<\/a>, watery eyes, and blurred vision.<\/p>\n\n\n

Corneal Abrasion<\/h3>\n\n\n

It is an injury to the cornea, the eye’s outermost layer.\u00a0

Corneal Abrasions<\/a> can occur if you get sand, dirt, metal particles, or other substances in your eyes.\u00a0

It can cause<\/a> Photophobia as a symptom.<\/p>\n\n\n

Conjunctivitis<\/h3>\n\n\n
\"Photophobia
Pink Eye<\/figcaption><\/figure>\n\n\n\n

Also called “pink eye<\/a>,” Conjunctivitis occurs when the layer of tissue covering your eye’s white part becomes infected or inflamed. 

Most cases of Pink eye may be viral, but bacteria and allergies can also cause it. 

It shows photophobia, eye pain, itching, and redness.<\/p>\n\n\n

Dry eye syndrome<\/h3>\n\n\n

Dry eye occurs when your tear glands can’t make enough or poor-quality tears. 

It can make your eyes excessively dry. Most patients<\/a> with ocular dryness symptoms report some degree of Photophobia.

Causes include age, environmental factors, some medications, and certain medical conditions.<\/p>\n\n\n

Glaucoma<\/h3>\n\n\n

Light sensitivity (or Photophobia) and glare are Glaucoma symptoms<\/a>. They make outdoor activities and driving more difficult.

\u00c8 caused<\/a> by the pressure buildup in the eyes that is common in glaucoma. 

Light sensitivity patients experience discomfort from sunlight, incandescent, and fluorescent lights. 

For those with Glaucoma<\/a>, halogen lights, such as those used in car headlights, and fluorescent store lighting or fixtures can also cause uncomfortable glare.<\/p>\n\n\n

Blepharospasm<\/h3>\n\n\n

Blepharospasm is the uncontrolled blinking or other eyelid movements, like twitching. 

As per AAO<\/a>, research by the University of Utah found that the participants with Blepharospasm were as light-sensitive as those with migraines.

It may also be innescato<\/a> by severely dry eyes, blepharitis, intraocular inflammation, meningeal irritation, and light sensitivity.<\/p>\n\n\n

Farmaci<\/h2>\n\n\n

Many medications<\/a> can temporarily induce Photophobia. For example, Tetracycline, an antibiotic, is commonly linked with Photophobia.

Some other medications that can trigger this effect include:<\/p>\n\n\n\n
