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.
Driving in Rain and
on
Wet
Roads
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.
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.
