If the abrasion is dirty, gently cleanse the area with a stream of clean water. Do not attempt to treat severe blunt trauma or penetrating injuries to the eye. Tape a paper or Styrofoam cup over the injured eye to protect it until proper care can be obtained. In the case of a blow to the eye, do not assume the injury is minor. The eye should be examined thoroughly by an ophthalmologist because vision-threatening damage could be hidden.
First aid is only the first step for emergency treatment.
If you experience pain, impaired vision, or any possibility of eye damage, call your ophthalmologist or go the emergency room immediately.
