# What causes photophobia?

Photophobia is abnormal sensitivity or discomfort in bright light. It can originate from eye surface problems, intra‑ocular disease, or neurological conditions.

## Ocular Causes

Corneal abrasions, keratitis, uveitis, and severe dry eye commonly produce marked light sensitivity. Post‑surgical states, albinism, aniridia, and some inherited retinal dystrophies also heighten glare.

- Red, painful eyes with photophobia often indicate serious inflammation or infection
- Meningitis and migraine can cause central photophobia with relatively normal eye findings
- Certain medications or dilating drops temporarily increase light sensitivity
- Long‑standing photophobia may be associated with iris or retinal abnormalities

## Clinical Importance

New or severe photophobia, especially with pain or reduced vision, requires prompt evaluation. Treatment targets the underlying cause and may include protective measures.

- Sunglasses, hats, and tinted lenses can improve comfort
- Persistent symptoms after injury or surgery should be reported
- Systemic symptoms like headache, neck stiffness, or fever warrant urgent medical care
- Diagnostic tests may include slit‑lamp examination and neurological assessment
