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
headlamps.
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 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 on the glass. Even the inside of 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 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 eyes
moving;
that
way, it’s easier
to
pick out dimly lighted
objects. Just as your headlamps should be checked
regularly for proper aim, 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.
Driving in Rain and on
Wet
Roads
W
Rain and wet roads can mean driving trouble. On a wet
road, you can’t stop, accelerate or turn as well because
your tire-to-road traction isn’t as good as on dry roads.
And,
if
your tires don’t have much tread left, you’ll get
even less traction.
It’s
always wise
to
go slower and
be cautious
if
rain starts
to
fall while you are driving.
The surface may get wet suddenly when your reflexes
are tuned for driving on
dry
pavement.
