(HealthDay News) -- Carelessly handled contact lenses, a low-hanging tree branch or a fingernail used to relieve an itch can scratch the eye's cornea, resulting in what is called a corneal abrasion.

The American Academy of Family Physicians offers these suggestions to reduce your risk of this injury:

  • Wear goggles when near machinery that could injure your eyes.
  • Cut your fingernails regularly.
  • Trim low-hanging tree branches.
  • Clean your contact lenses properly each day, and be careful when placing them on your eye.
  • Always take contact lenses out before going to sleep.
