Road-Bleary Eyes

8 Dec

It happens to everybody. You’re driving your car on a long road trip and suddenly your eyes start burning and you can’t keep them opened. You start nodding off, and sensing imminent disaster, you quickly pull off the road and take a nap. In an hour or so, you continue on your way, feeling much better.

But what would you do if you were an airline pilot and that happened? Or a tank driver during a war? Or an ambulance driver rushing to the hospital?

Actually, the cause may not be fatigue. Often, the cause is a reduction in the moisture content of the delicate tear film covering the external surface of your eyeballs. Pollution, heat, fatigue, car air-conditioning, and intense concentration (with not enough blinking), can all cause tear film moisture loss. Loss of tear film moisture increases the concentration of salts and other natural substances resulting in the familiar burning sensation. When you take a nap, your eyes are closed and your body is able to restore the depleted moisture.

The solution: Get plenty of rest, drink plenty of water (which will also help assure that you pull over and rest occasionally), make sure you blink often enough, and keep a pH Balanced water mist spray nearby as you drive.
