Your

Driving

and

the

Road

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 as

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’t wear

sunglasses at night. They may cut down

on glare from headlights, but

they

also

make a lot of things invisible

that

should

remain visible

-

such as parked cars,

obstacles, pedestrians, or even trains

blocking railway crossings.

You

may

want to put on your sunglasses after you

have pulled into a 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 before you 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 with severe glare

(as

from

a driver who doesn’t lower the high

beams, or a vehicle with misaimed

headlights), slow down a little. Avoid

staring directly into the approaching

lights. If there is a line of opposing

traffic, make occasional glances over the

line of headlights to make certain that

one of the vehicles isn’t starting to move

into your lane. Once you are past the

bright lights, give your eyes time to

readjust before resuming speed.
