Researchers have discovered that myopia can be successfully
treated if special lenses are fitted before it gets too bad.

Then, disaster struck, and Otis Brown's dreams of becoming a

glasses to correct a worsening case of myopia, or nearsightedness,
a condition which causes distant objects to appear blurred.

a condition which causes distant objects to appear blurred.
Brown was born too soon. Today, there is good reason to
believe, if his parents could take that same 10 year old boy to an
optometrist, there is at least a 50-50 chance that Brown would
never have to wear a pair of glasses or contact lenses to see
distant objects. And, instead of being limited to flying his
home-built, Volkswagen powered cub plane, Otis Brown might have
the regular Pan Am route between Philadelphia and Paris.

It is only in the past few years that substantial numbers of
optometrists have begun using a radically new treatment, involving
"plus" lenses, that is said to keep myopic eyes of children from
deteriorating further, and even to cure or prevent myopia. It is
a direct contradiction to the more traditional forms of treating
nearsightedness which use "negative" lenses that bring distant
objects into sharp focus.

When rays of light enter the eye, they are bent by the eye's
lens so that they converge on a single point on the retina of the
eye. The retina, it should be noted, is the inside coating of the
eyeball. Although it is only the thickness of a newspaper page,
it contains 10 distinct layers and between 125 and 150 million
sensing rods which we use to see directly ahead and to all sides,
according to Dr. Harris Gruman (New Ways to Better Sight,
Hermitage House, 1950).

In the individual with myopia, the eye has adapted itself to
the reading environment. Therefore the light rays converge on a
single point in front of the retina, making distant objects appear
blurred. The traditional treatment for this problem has been to
fit the patient with negative (or minus) lenses which make an
adjustment to the light rays, resulting in their finally being
focused on the retina.

If some of the optometrists now doing research on myopia are
correct, then the child should be using a plus lens for
prevention, rather than the traditional minus lens. Although a
direct opposite treatment, the plus lens may be the right one to
actually prevent the eye from developing a negative focal state
(nearsightedness).

prevention, rather than the traditional minus lens. Although a
direct opposite treatment, the plus lens may be the right one to
actually prevent the eye from developing a negative focal state
(nearsightedness).
Here's how it works.
The eye functions by "accommodation," which is the term used
to describe how the focusing apparatus of the eye adjusts to
objects at different distances. "Accommodation" takes place by
increasing the convex shape of the eye's lens through adjustment
of the ciliary muscles in response to blur sensed at the surface
of the retina.

of the ciliary muscles in response to blur sensed at the surface
of the retina.
In man, according to some of the researchers, the eye's
normal function is programmed to distant objects. But, by
starting children in school at an early age -- and keeping them
there -- as well as letting television baby sit them -- the eye's
"long-term focusing" adjusts to close-up work. To perform the
adjustment the eye alters its corneal curvature and length,
thereby blurring its distance vision.

thereby blurring its distance vision.
TREATMENT STARTS WHEN SQUINTING BEGINS
The positive lens advocates believe that when a child starts
squinting in school -- one sign that may mean myopia is right
around the corner -- the child should be fitted with weak positive
lenses. The positive lens, which is a magnifying glass, minimizes
the need for large amounts of accommodation.
squinting in school -- one sign that may mean myopia is right
around the corner -- the child should be fitted with weak positive
lenses. The positive lens, which is a magnifying glass, minimizes
the need for large amounts of accommodation.
For example, when a child dons a pair of plus glasses,
(strong enough to neutralize the near enviroment) the reading
material will become clearer, since the plus lens is a magnifying
lens. This means that the eye's accommodation process does not
have to work at all for close work. When the child stops his
reading to look at something in the distance -- the distant
objects will be clearer.

objects will be clearer.
And in order to minimize the number of times a child might
have to put on and take off his glasses, those who advocate the
use of positive lenses recommend either a full-face plus, or a
half-lens or "granny" glasses, so that the child can look over the
positive lenses when gazing at distant objects.

What happens, on the other hand, if the child who develops a
ease of myopia is fitted with a pair of negative lenses?

The negative lens corrects the blurred image and distant
objects literally leap into focus the minute the glasses are put
over the nose. But, the negative lenses do not correct the
overall problem of accommodation, and in fact move all objects
(optically) closer to the eyes.

The basic problem of adjustment to close-up work still
exists. And what's worse is that the eye will continue on the
same path, developing a worsening case of myopia. This means that
until the individual is about 25 or so, he will continue to need
stronger and stronger negative lenses until the myopia gradually
grinds to a halt.

Even then, there is no guarantee it will stop. And besides
having to wear glasses every waking minute, the individual winds
up spending anywhere from $600 on up to thousands of dollars for
new glasses during the course of his life.

On the other hand, there is a good chance that if a child is
fitted with positive lenses, he can slowly work his way out of a
myopic state to the point where he will never have to wear
negative glasses. By this theory, the use of plus lenses enables
the child to use his distance vision all the time, keeping the
myopia from developing further, and in many cases eliminating it.

Does the "positive lens" theory work?
"Yes, definitely," says Dr. William M. Ludlam, an
optometrist who formerly directed the Laboratory for Myopia
Research in New York and is now working on a year-long National
Institutes of Health grant at the University of the Pacific.
"I've used that method for the past 20 years and have had good

Dr. Ludlam believes that myopia can be cured and, what's
more important, can actually be prevented through development of
good reading and other eyesight habits such as holding books
farther away from the eyes during reading and frequently looking
at distant objects during and after long periods of reading.

One time an accountant brought his young son to Dr. Ludlam
for treatment of headaches associated with long periods of
reading. After fitting the son with positive reading glasses and
prescribing a series of visual exercises, Dr. Ludlam was asked if
he could cure or at least help the accountant's myopia.

"The accountant had normal vision up until he was about 23 or
24. In fact he had served in the Air Force. But by the time he
came to me, he had 20/400," Dr. Ludlam said.

20/400 means that the accountant who was in his early 30's
could see at 20 feet what people with perfect vision could see at
400 feet. In practical terms, he could read only the largest
letter on an eye chart.

Dr. Ludlam treated the accountant with a series of exercises
and positive lenses which increased the eye's flexibility. "I
brought him down from 20/400 to 20/80 and 20/40 where he is now
and I've held him there," Dr. Ludlam said. "He-still wears
glasses to drive, for the theater and to watch television, but
other than that, he doesn't need them especially for his close-up
work."

Dr. Ludlam has done the same for children, bringing them
from extremely poor distant vision right down to 20/40 through
exercises and positive lenses and "held them there for 10 years.
I reported on 30 cases that I treated for over a 10 year period of
time, so I know it can be done. They're still there today."

NOT ALL MYOPIA RESPONDS
There are two different kinds of myopia that Dr. Ludlam has
studied. One is caused by pressure of the eye growing too fast,
causing the eye to become elongated. "It literally grows right

Treatment calls for fitting the eye with contact lenses which
press the eye into focus, acting like a "pressure bandage." If a

is a good chance that the myopia will be caught and not progress
further, he noted.

But the other type of myopia can be reversed. It's caused by
a spasm of the ciliary muscles. For example, a person is reading
and then looks up. If the eye fails to focus on a distant object,
the ciliary muscles are believed to be undergoing spasms.

times, he's accurately describing a ciliary spasm," Dr. Ludlam
said.

lenses which tend to take the close-up environment and push it
outwards, increasing the reading distance.

someone who does this continually will become nearsighted very
quickly."

"There are indications that nearsightedness is caused by a
number of things such as the environment, nutrition and function
(i.e. reading)," Dr. Ludlam told PREVENTION. "There are cases
where one aspect of the problem is more important than the other.
For example, if a child eats a well-balanced diet and lives in a
good home, but all of a sudden becomes a book worm and develops
myopia, it's pretty obvious what the cause is."

The study of 204 children in grades 3, 4, 5 and 6 in Alaska

The optometrist is now in the process of analyzing data on
525 children with an NIH grant. While in New York he and his
associates followed these children for several years, taking down
all the information they could, ranging from the size of the
eyeball to total weight. Now, the information is being analyzed
by computer.

"In a year, we should have most of the answers about what

Dr. Ludlam also believes that heredity can pretty well be
discounted as a cause of myopia simply because of the fact that it

A lower Bucks County (Pa.) optometrist, Dr. Carl Cordova

But, the onset of myopia is a gradual one. It can happen
over a year or two and a person might first be conscious of it
after being examined. And, as Dr. Cordova pointed out, patients
want the blurred vision eliminated almost immediately. They will
not take the time to effect a cure but will settle for having
their distant vision cleared with a minus lens. A cure, however,
can take almost as long as the eye took to reach the point at
which correction started.

A variations of the positive lens cure, Dr. Cordova said, is
to fit the patient with bifocals containing a reading (positive)
lens on the bottom, and a negative lens of a lower power than
needed on top. He has had success with patients using that method
and was eventually able to almost completely corrected myopia in
patients who were willing to use the treatment.

Almost a universal problem of parents today revolves around
the question: "How can I prevent my child from becoming

There are several ways, the first of which begins in the
crib. Mothers, according to Dr. Amiel Franke, of Washington,
D.C., should keep a child out of the playpen as much as possible.
By stimulating the baby's eyes they are given more of a chance to

his vision growth and development is limited too," he told a

should be within his sight at all times.

of course, most refined foods and sugars were unavailable.

In experiments conducted at the Columbia College of
Physicians and Surgeons by Dr. Arthur A. Knapp, animals were fed
diets deficient in vitamin D and calcium. The animals developed
an amazing variety of eye problems including myopia (Medical World

as those produced in the animals.

Unfortunately, all of this "new" information comes much too
late for Otis Brown. His eyes are bad and they will remain that
way. But, despite his run of bad luck and being born 20 or 25
years too early, he hasn't lost his zest for evangelism and
constantly warns others against accepting negative lenses too
readily without examining the alternative.
"Parents should know that there is an alternative for their
children," Brown said. "But this alternative stops later on in
life. If they can stop myopia early, they should be able to take
advantage of it and use the preventive process.

"The biggest advantage to trying the positive lens approach
is that it is completely harmless. It can't hurt." But, Brown
continued, "it could help tremendously. If the child is 8, 9, 10

If the condition has developed over a year or a year-and-a-half,
