Ideally, a second person should perform steps 1 through 3, as the victim may be in extreme discomfort, particularly if both eyes are affected. If a clean cup is not available, tip your head back and pour water over the affected eye(s). Try to avoid blinking during the first few seconds of flushing. If water is not available, then eye drops can be used to aid in eye flushing. If water is unavailable, then allow the eye to tear. Although this will lead to discomfort for a longer period of time, the sand will be flushed out of the eye. The chances of a corneal abrasion are much higher if water is not available to flush the victim's eyes. If eye flushing does not remove a foreign object, seek emergency medical attention. In addition, a person with a corneal abrasion may feel like there's an object in the eye, so a medical exam is essential to determine the true nature of the situation.
