What term describes a sensitivity to light?

Photophobia is the correct term used to describe a sensitivity to light. This condition can cause discomfort or pain in the eyes when exposed to bright light or sunlight. It can be a symptom of various underlying issues, including eye conditions, migraines, or inflammation. Understanding photophobia is important for eye care practitioners, as it can significantly affect a person's quality of life and may signal the need for further examination or treatment.

Presbyopia refers to the age-related difficulty in focusing on close objects and does not relate to light sensitivity. Pannus is a term that describes a growth of tissue over the cornea, often due to inflammation or irritation, rather than sensitivity to light. Ptosis is the drooping of the upper eyelid, which also does not relate to sensitivity to light. Recognizing these distinctions is crucial for anyone studying eye care and conditions associated with visual health.
