Uight ;ion No one can see as well at night as in the daytime. But as A we get older these differences increase. 50-year-old driver may require at least twiceas much light to see the same thing at night as a 20-year-old. What you do in the daytime can 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. But if you're driving, don'twear sunglasses at night. They may cut down on glare fromheadlamps, but they also make a lot of things invisible. Keep your windshield and all the glass on your vehicle clean -- inside and out. Glareat night is made much worse by dirt on the glass. Even the inside of the glass can build up a filmcaused by dust. Dirty glass makes lights dazzleand flash more than clean glass would, making the pupils of 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. Justas your headlamps should be checked regularly for proper aim, should your eyes so be examined regularly. Some driverssuffer from night blindness -- the inability to see in dim light -- and aren't even aware of it. 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 (as from a driver who doesn't lower the high beams, or avehicle with misaimed headlamps), slow down a little. Avoid staring directly into the approaching headlamps. 4-15
