Causes of Corneal Abrasion

Corneal abrasions can be painful where individuals complain of having sand in their eye and some usually develop a headache. There are various scenarios that can cause corneal abrasion.

  • Exposure to sand, dirt, ash, sawdust and other foreign materials
  • Being poked in the eye by a plant, makeup brush or fingernail

  • Chemical burns
  • Dirty or ill-fitting contact lenses
  • Certain eye infections
  • Inadequate protection of eyes during surgery while under general anesthesia

  • Instruct individual to blink the eye numerous times. This might remove the foreign objects present in the eye.
  • Tug the upper eyelid above the inferior eyelid  so that the lashes of the lower eyelid will brush out any foreign particle that might be present in the lower surface of the upper eyelid. Just be careful to avoid unnecessary actions that might worsen the condition.
  • Avoid removing a foreign object that is embedded in the eyeball. Do not remove large objects that will make it difficult for the eye to close.
  • Instruct individual to avoid rubbing the eye after an injury since it will worsen the corneal abrasion.
