Photophobia, known generally as light sensitivity, is another possible reason for eyelid spasms. Mild cases may make an individual squint in brightly lit areas, while more severe cases can cause extreme pain. One of the common causes of temporary photophobia is migraines. Other causes include encephalitis, meningitis, and bleeding between the brain and its surrounding tissues. Pink eye, dry eye, conjunctivitis, and cornea injuries can also lead to light sensitivity.
