  • The feeling of something in your eye
  • A scratchy feeling in the eye
  • The eye may water excessively
  • Sensitivity to light
  • A crustiness that forms along the eyelid

  • A bump on the eyelid that is usually not painful
  • In some rare cases, an entire swollen eyelid
  • If the bump becomes large, it can press on the eyeball and cause blurry vision
