A foreign object in the eye should be taken seriously. If your child feels something in his/her eye, do not let him/her rub it. Rubbing can damage the cornea, the clear tissue covering the coloured part of the eye.
Most eye injuries are preventable. Use common sense and take a few precautions when there is potential for eye injury.
