Photophobia

Abnormal intolerance to light, often associated with albinism, drug-induced pupil dilation, migraine, encephalitis, measles, and other diseases.


Abnormal sensitivity to, and intolerance of, light. Photophobia can be a symptom of a variety of diseases and conditions, such as excessive wear of contact lenses, eye injury or infection, inflammation, migraine headache, meningitis (inflammation of the brain covering), and reaction to certain medications. Photophobia should be evaluated by a medical professional if it is unexplained, persistent, or accompanied by blurry vision or red eyes.


An abnormal intolerance of light, in which exposure to light produces intense discomfort of the eyes with tight contraction of the eyelids and other reactions aimed at avoiding the light. In most cases the light simply aggravates already existing discomfort from eye disease. Photophobia may be associated with dilation of the pupils as a result of drug administration, migraine, measles, German measles, or meningitis.


Sensitivity to light. It can occur in migraine, disorders of the eye, or in meningitis.


Unusual intolerance of light, occurring in measles, rubella, meningitis, and inflammation of the eyes.


A distressing heightened sensitivity or inability to tolerate light. This phenomenon is observed in specific eye conditions, such as corneal abrasion, and is also a characteristic symptom of meningitis (inflammation of the membranes enveloping the brain and spinal cord).


A sensitivity to light, like the one observed in children with measles, where their eyes become red, painful, and easily irritated. Intense light sensitivity is termed photodynia. It’s also known as photodysphoria.
