Correct, the proper term for light sensitivity is photophobia. Photophobia is a common symptom of various eye conditions and may result from conditions that affect the eye or other conditions such as migraines. Common eye conditions that may cause photophobia include uveitis, corneal abrasions, and iritis. Photophobia is not a medical condition and is not considered a disease on its own. It is a symptom that typically accompanies other underlying medical conditions. Treatment of photophobia involves treating the underlying condition causing it.
