Night

Vision

one can see as well at night as in the daytime. But as

we get older these differences increase.

50-year-old

driver may require at least twice

much light to see the

same thing at night as a 20-year-old.

What you

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

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

headlamps. It can take a second

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,

vehicle with

misaimed headlamps), slow down

little. Avoid staring

directly into the approaching headlamps.

Keep your windshield and all the glass on your vehicle

clean

inside

and

out. Glare at night is made much

worse by dirt

the glass. Even the inside

the glass

can build up a film caused by dust. Dirty glass makes

lights dazzle and flash more than clean glass would,

making the pupils

your eyes contract repeatedly.

Remember that your headlamps light up

far

less

roadway when you are in

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

be examined regularly. Some drivers suffer from night

blindness

the inability to see in dim light

and

aren’t even aware of it.
