Photophobia is a symptom of abnormal intolerance to visual perception of light.[1] As a medical symptom, photophobia is not a morbid fear or phobia, but an experience of discomfort or pain to the eyes due to light exposure or by presence of actual physical sensitivity of the eyes,[2] though the term is sometimes additionally applied to abnormal or irrational fear of light such as heliophobia.[3] The term photophobia comes from the Greek ฯแฟถฯ (phลs), meaning "light", and ฯฯฮฒฮฟฯ (phรณbos), meaning "fear". Photophobia is a common symptom of visual snow.[4][5]
