Photophobia

Photophobia
SpecialtyOphthalmology

Photophobia is a medical 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 Greek φῶς (phōs) 'light' and φόβος (phóbos) 'fear'.[4][5]
