Night Vision No one can seeas well at night as in the daytime. But as A we get older these differences increase. SO-year-old driver may require at least twice much light to see the as same thing at night a 20-year-old. as What you do in the daytime can also affect your night in vision. For example, if you spend the daybright 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 They may cut down on glare from headlights, but also make a lot of things invisible that should remain visible - such as parkedcars, obstacles, pedestrians,or even trains blocking railway crossings. You may want to a put on your sunglasses after you have pulled into brightly-lighted service or refreshment area. Eyes shielded from that glare may adjust more quickly to darkness back on the road. But be sure to remove your sunglasses beforeyou leave the service area. 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 a with severe glare (as fromdriver who doesn't lower the high beams, ora vehicle with misaimed headlights), slow down a little. Avoid staring directly into the approaching lights. If there is line of opposing traffic, a of make occasional glances over the line headlights to make certain that one the vehicles isn't starting to of move into your lane. Once you past the bright lights, are give your eyes time readjust before resuming speed. to High Beams If the vehicle approaching you has its high beams on, to signal by flicking yours to high and then back low beam. This is the usual signal to lower the headlight beams. If the other driver still doesn't lower the beams, resist the temptation to put your high beams on. This only makes two half-blinded drivers. On a freeway, use your high beams only in remote areas where you won't impair approaching drivers. In some places, like cities, using high beams is illegal. When you follow another vehicle onfreeway or a highway, use low beams. True, most vehicles now have day-night mirrors that enable the driver to reduce glare. But outside mirrors not of this type and high beams are from behind can bother the driver ahead. 170
