What condition is described as an abnormal fear of light?

The condition characterized by an abnormal fear of light is indeed known as photophobia. This term specifically refers to heightened sensitivity to light, which can cause discomfort or anxiety. Individuals who experience photophobia may not only feel pain or discomfort in bright environments but may also develop an irrational fear or aversion to light altogether.

This condition can be caused by various factors, including underlying medical issues such as migraines, eye disorders, or certain neurological conditions. Understanding photophobia is important in the field of sports medicine since athletes may experience this symptom due to injuries or fatigue, impacting their performance and well-being.

The other choices refer to different phobias: nyctophobia pertains to the fear of the dark, claustrophobia involves fear of confined spaces, and agoraphobia is the fear of situations that may cause panic or embarrassment, particularly in public spaces. Each of these conditions has distinct characteristics and triggers, but none relate to a fear of light.
