causes of light sensitivity
Light Sensitivity. Light sensitivity is a hypersensitivity to light. A sudden onset of substantial or even painful light sensitivity (photophobia) may be caused by inflammation in the eye. This may be due to a foreign body in the eye, eye allergy, an infection of the cornea or an inflammation of the iris or uvea. This may also occur after having LASIK or cataract surgery. A gradual onset of less severe sensitivity to light may be associated with cataract or tear film abnormalities such as dry eyes.
