Abnormal fear or intolerance of light. It can be physiological, although it often accompanies inflammations of the anterior segment of the eye, especially anterior uveitis. It is also noted in patients with cone degeneration. Management is usually aimed at treating the primary cause (e.g. keratitis, uveitis), but in other cases (e.g. albinism, drug-induced mydriasis, recent aphakes, fear of light) tinted lenses will give relief. See albinism

Patient discussion about photophobia
Q. I had cataract surgery with iol implant, and ever since I have awful light sensitivity. Any ideas? I can't go into a "super store" without my sunglasses. My eyes ache at the end of the day.
My doctor says "I don't know!"
A. May sound a bit silly question, but have you tried to consult your ophthalmologist (eye doctor, e.g. the one that performed the operation) about it? Cataract surgery, although considered very successful, isn't problem-free. Primary physician may not have the necessary specialization to deal with these subjects.
Q. Hey ! i am sensitive to light , every time i go out with a short sleeve i get this red rush all over.. what can i do ?
A. You should see a dermatologist or even your personal physician when this happens. Sensitivity to light is common in various medical conditions you should get checked up for.More discussions about photophobia
