supply Of visual purple is not SUI
ficient to replace the pigment
promptly and fully, as 1t must be
by the proper degree OF healthy
tissue in the eye, the return TO
normal vision is too slow for safe
ty. This is what happens when
the eye is subjected to the bright
glare Of automobile lights at night.
The supply Of visual purple is re-
duced below the point of safety by
the glare of light, and on passing
the fash of brightness, the driver
is fronted by nothing but black
darkness. In the moment or two
required to allow the vision to re-
turn to normal, many things may
occur and the fact that they do
occur is noted in the multiplied
accidents.
How Eyes Are Tested
We have now developed an in
strument that tests drivers eyes
for this defect. What is known as
1.-The recovery time limit" is indi-
Gated by the results Of careful
test with this instrument, in the
process of which the eye Is sub
1ected first to bright light and
then to normal illumination. In
fact, one may carry on a simple
test by having the eye first focused
on a bright light, as white cleo
trio light bulb. then on a green
one, and then red one, as in or
binary traffic, ending on return to
green, since that sense seems to be
the harder to recover.
The time included in this test
Is the answer to the questions that
involve your fitness to drive your
car in safety. Age has something
to do with the subject, but Is not
a determining factor. In fact, the
situation is similar to the one
when you try to cross a congested
intersection. If you are quite nim-
BILE you are comparatively safe.
but II you are slow and stiff, the
traffic may get the jump on you.
It is the same way with your OPP
tical nerves; If they are quick to
adapt themselves to changes In
strain, you are not likely TO be
blinded by excessive lights, but II
they recover slowly from glare,
then beware.
From the angles of both optical
survey and nutritional tests, 1t has
been decided that we must have
the food which supplies vitamin
A If we want to have our proper
supply of visual purple to make
standard vision. Even in supposed
ly good diets, it was found that
this element was often missing.
Green Foods Essential
The outer or green leaves Of
iceberg lettuce are proven to have
from thirty TO forty times as much
vitamin A as the bleached inner
leaves which are all We usually put
on the table. Besides lettuce and
cabbage, we can depend on green
beans. peas, peppers, and all the
-stalked vegetables II we do
not throw the outer stems away
Select yellow corn and yellow
hominy If you want the best in
nutrition. There has been some
difficulty in my own family in con-
verting tastes to using yellow corn
meal for mush instead Of white.
This whole matter is being care
fully worked out by the Bureau Of
Home Economics in the Depart
ment OF Agriculture. The final
verdict is that We must quit dis
carding the outer colored leaves
Of our garden products. and eat
our food las is" In order to get
all the benefit OF the natural
properties as they are grown into
the product In its development for
the table. Eat yellow and green,
they insist, and I add the red
since many fine qualities are found
In red beets. cabbage and red
fruits. Butter, eggs, cheese and ice
cream are among the other de-
sired foods.
Lacking the proper elements OF
diet, the only recourse is to pre-
scribe fish liver oils and carotene
as marketed for these deficiencies.
It is much simpler TO abide by nat
ural laws.
