What is photophobia?

Photophobia refers to extreme sensitivity to light, a condition where bright lights can cause discomfort or pain in the eyes. This sensitivity can result from various underlying conditions, such as migraines, eye infections, or inflammation. Individuals experiencing photophobia may find it challenging to be in well-lit environments or exposed to sunlight, often needing to wear sunglasses or stay in dimly lit rooms to alleviate their discomfort. Understanding this condition is crucial for recognizing its impact on a person's daily activities and quality of life.

The other choices describe different sensations or conditions that are not related to photophobia. For example, a fear of the dark is known as nyctophobia, intolerance to loud noises is referred to as hyperacusis, and loss of vision pertains to various visual impairments but does not encompass sensitivity to light.
