Night Vision No one can see as well at night as in the daytime. But as we get older these differences increase. A 50-year-old 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 daytime can also affect your night in vision. For example, if you spend the day bright sunshine you are wise to wear sunglasses.Your eyes will have less trouble adjusting to night. Butif you're driving, don't wear sunglasses at night. They cut may down on glare fromheadlamps, but they also make lot a of things invisible. You can be temporarily blinded by approaching headlamps. It can take a second ortwo, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare(as from a dnver who doesn't lower the high beams, or a vehicle with misaimed headlamps), slow down a little. Avoid staring directly into the approaching headlamps. 4-15
