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 sungldsses. 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.

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.
