Night Vision No one can see as well at night as in the daytime. But aswe get older twice these differencesincrease. A SO-year-old driver may require at least as much light to see the samething 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't wear sunglasses at night. They may cut down on glare from headlamps, but they also make a lot of things invisible. You can be temporarily blinded by approaching lights. It can take a second or two, or even several seconds, for your 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 a vehicle with misaimed headlamps), slow down a little. Avoid staring directly into the approachinglights. Keep yourwindshield and all the glass on your vehicle clean -- inside and out. Glare at night is made much worse by dirt on the glass. Even the inside of the glass can build up a film caused by dust. Dirty glass makes lights dazzle andflash more than clean glass would, making the pupils of your eyes contract repeatedly. Remember that your headlamps light up far less of a roadway when you are in a turn or curve. Keep your cyes moving; that way, it's easier to pick out dimly lighted objects. Just asyour headlamps should be checked regularly for properaim, so should your eyes be examined regularly. Some drivers suffer from night blindness -- the inability to see in dim light -- and aren't even aware of it.
