Night Vision No one can see as well at night as in the daytime. But as we get older these differences increase. 50-year-old A driver may require at least twice asmuch light to see the same thing at night as a 20-year-old. What you do in the daytimecan also affect your night vision. For example, if you spend the day in bright sunshine you are wise to wear sunglasses. Your eyes will have less trouble adjusting to night. if you're But driving, don'twear sunglasses atnight. They may cut down on glare from headlamps, but they also make a lot of things invisible. You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, foryour eyes to readjust to the dark. When you are faced with severe glare (asfrom a driver who doesn't lower the high beams, or a vehiclewith misaimed headlamps), slow down a little. Avoid staring directly into the approaching headlamps. Keep your windshield and all the glass on your vehicle clean -- inside and out. Glare atnight is made much of worse by dirt on the glass. Even the inside the glass can build up a filmcaused by dust. Dirty glass makes lights dazzleand flash more than clean glasswould, making the pupilsof your eyes contractrepeatedly. Remember that your headlamps light up far lessof a roadway when you are in a turn or curve. Keep your eyes moving; that way, it's easier to pick out dimly lighted objects. Just as your headlamps should be checked regularly for proper aim, should your eyes so be examined regularly. Some drivers suffer from night blindness -- the inability to see in dim light -- and aren't even aware of it. 4-17
