Photo phobia is a condition in which bright lights hurt the eyes. This condition also called Light sensitivity . It’s a common symptom that’s associated with several different conditions, ranging from minor irritations to serious medical emergencies.
Migraine : Photophobia is a common symptom of migraine. Migraine causes severe headaches that can be triggered by a number of factors, including hormonal changes, foods, stress, and environmental changes. Other symptoms include throbbing in one part of your head, nausea, and vomiting.
Conditions That Affect the Brain : Light sensitivity is commonly associated with a few serious conditions that affect the brain. These include:
Encephalitis : Encephalitis occurs when your brain is inflamed from a viral infection or other cause. Severe cases of it can be life-threatening.
Meningitis : Meningitis is a bacterial infection that causes inflammation of the membranes surrounding the brain and spinal cord. The bacterial form can lead to serious complications such as brain damage, hearing loss, seizures, and even death.
Subarachnoid hemorrhage : A subarachnoid hemorrhage occurs when you have bleeding between your brain and the surrounding layers of tissue. It can be fatal or lead to brain damage or a stroke.
Photophobia is also common in several conditions that affect the eyes. These include:
Corneal abrasion : A corneal abrasion is an injury to the cornea, the outermost layer of the eye. This type of injury is common and can happen if you get sand, dirt, metal particles, or other substances in your eyes. This can lead to a serious condition called a corneal ulcer if the cornea becomes infected.
Scleritis : Scleritis occurs when the white part of eye becomes inflamed.
Conjunctivitis : Also known as “pink eye,” conjunctivitis occurs when the layer of tissue that covers the white part of your eye becomes infected or inflamed. It’s mostly caused by viruses, but it can also be caused by bacteria and allergies. Other symptoms include itching, redness, and eye pain.
Dry eye syndrome : Dry eye occurs when tear glands can’t make enough tears or make poor-quality tears. It results in your eyes being excessively dry. Causes include age, environmental factors, certain medical conditions, and some medications.
