photophobia

[‚fōd·ə′fō·bē·ə]
(psychology)
An abnormal fear of light.

Photophobia

 

an increased visual sensitivity to daylight or artificial light. Photophobia may develop as a result of the inflammation of the anterior chamber of the eye (conjunctivitis, keratitis, and iridocyclitis), the entry of foreign bodies into the cornea, and the irritation of the unprotected eye during electric arc welding (electrophthalmia). Photophobia may also develop with albinism or with the artificial dilatation of the pupils after they fail to contract upon exposure to light, subjecting the retina to light rays. The condition is manifested by eyelid spasms, tearing, and eye pain.

Photophobia is treated by eliminating the main cause and by wearing dark glasses.
