What Causes A Sensitivity To Light?

Uveitis

Light sensitivity may develop due to uveitis, a condition where an individual's uvea, the middle tissue layer of the eyewall, becomes inflamed. This condition can affect both or one of an individual's eyes. Uveitis is caused by an inflammatory disease, injury, autoimmune disorder, or an infection. Uveitis can cause a patient to experience eye redness, blurred vision, poor vision, eye pain, floaters, and sensitivity to light. Symptoms occur rapidly and progress quickly in affected individuals. Uveitis can cause certain parts of the eye to lose function temporarily. The parts of the eye responsible for detecting and absorbing light can become impaired because of the inflammation of eye tissues. When the eye is not able to properly adjust to brighter light conditions very well, the affected individual will experience increased sensitivity to light. As long as a patient receives treatment within a reasonable time, photophobia caused by uveitis is usually not permanent.
