When is light sensitivity urgent?

Bottom Line

Photophobia means light hurts or feels too bright. It can come from dry eye, migraine, inflammation, infection, injury, or a nerve problem.

Photophobia is discomfort or pain from light. It is a symptom, not a single disease ¹.

Common causes include dry eye, migraine, cornea scratches, eye inflammation, and some brain or nerve conditions. The right treatment depends on the cause ².

Light sensitivity with severe eye pain, vision loss, injury, fever, or a contact lens red eye needs urgent care. These can signal infection or inflammation that threatens sight.

Common Causes

Photophobia can come from the eye surface, inside the eye, or the brain's light pathways. It often overlaps with dry eye and migraine ².

Dry eye. The surface nerves become irritated.
Migraine. Light can trigger or worsen head pain.
Cornea scratch or infection. This often causes tearing and sharp pain.
Uveitis. This is inflammation inside the eye and can cause deep ache.
Recent surgery or injury. These need prompt checks if symptoms worsen.

When To Seek Care

Go to the emergency room now for sudden vision loss, severe pain, chemical splash, injury, fever with stiff neck, or confusion. Contact lens pain with redness or discharge needs same-day urgent eye care. After eye surgery, call your surgeon now.

Routine sunglasses can ease symptoms. They should not replace an exam when light sensitivity is new, one-sided, painful, or linked with blurry vision.

Common Questions About Photophobia

No. Photophobia is a symptom. The cause may be dry eye, migraine, inflammation, infection, injury, or a nerve problem ¹.
