Also known as: Photophobia
Light sensitivity makes normal light levels uncomfortably bright, causing squinting, eye pain, or headache. It accompanies many eye and neurological conditions.
Photophobia is not an eye disease but a symptom of many conditions. The degree can range from discomfort in bright sunlight to inability to tolerate any light.
Migraine is the most common neurological cause, with photophobia occurring in up to 80% of migraine attacks. The trigeminal nerve pathway connecting the eyes to the brain amplifies light signals during attacks.
Eye surface conditions like corneal abrasions, conjunctivitis, and uveitis cause photophobia through direct irritation of pain-sensitive eye structures.
There are several possible reasons you may be experiencing Sensitivity to Light. Here are the most common ones.
Neurological hypersensitivity during migraine attacks makes normal light painfully bright.
Scratch on the cornea exposes pain nerves, causing severe light sensitivity.
Eye surface inflammation from infection or allergy increases light sensitivity.
Inflammation inside the eye causing deep aching pain and photophobia.
These approaches may help manage sensitivity to light at home. Always consult a healthcare provider if symptoms persist or worsen.
Wear quality sunglasses outdoors. Avoid wearing them indoors as this can worsen sensitivity.
Use adjustable lighting and screen brightness to find comfortable levels.
Slowly increase light exposure rather than sudden changes.
Eye examination including slit lamp, pupil response testing, and neurological assessment if brain-related cause suspected.
Seek immediate care if photophobia is accompanied by severe headache, neck stiffness, fever, or vision changes — these may indicate meningitis or other serious conditions.
Steps you can take to reduce the likelihood of experiencing sensitivity to light.
Manage migraines proactively
Protect eyes from injury
Treat eye infections promptly
Adjust screen brightness
Sudden photophobia may indicate migraine, eye infection, corneal injury, or rarely, meningitis. See a doctor if severe.
The symptom itself isn't dangerous, but it can indicate conditions ranging from minor to serious depending on accompanying symptoms.
Prolonged screen use can cause temporary light sensitivity from eye strain. Regular breaks help prevent this.
