I have read that squinting can only be beneficial.  On the other hand I
have head squinting will halt all progress in myopia prevention.  I
have also heard that people become myopic from squinting to see in the
first place.  Does anyone know about this?

It's easier to see when you squint because smaller openings focus better.
Look up "depth-of-field." It doesn't change your myopia, just counteracts it
until you stop squinting.

I haven't heard that.

I'm pretty sure squinting won't make any difference in your myopia
prevention.

It's pretty likely people squint because they get myopia, not the other way
around.

Farsighted people squint too. They usually get more farsighted, no matter
what.

Dear Friend,
(Interesting email name)
After spending long hours, weeks, months, years at "close work", you
may find that objects are slightly "burrry" out their.

If you squint, that reduces the aperture of the eye, and increases your
depth-of=field.  This can "improve" image-sharpness because of this
optical effect -- and will produce clearing for that reason.

Squinting is a normal response to slight blur at distance.

I know what squinting does, you guys.  But I was just wondering why
this book I bought which is based on the Bates method says not to
squint because squinting prevents your eye from healing, by which i
mean becoming less myopic.

Usenet offers a group specifically for discussing these techniques - it's
alt.med.vision.improve.

Bates' book is full of drastic, dramatic conclusions based on anecdotes and
his own intuition. Don't worry if some of it doesn't make sense. People who
take college physics and physiology and anatomy always have problems
understanding Bates.

I should think you would want your money back.

My guess is that Bates and his "groupies"  think that any stress (such
as
squinting) with the muscular (ocular) system is detrimental. Which is
why
"relaxation" exercises are important in Bate's philosophy. Maybe a
Bate's proponent
could be more specific. BTW, myopia is not a "disease" so there is
no "healing" needed to take place.

Yes, Frank is right.

Nearsightedness is not a "disease" -- it is an undesired negative
refractive state of the natural eye.

An engineering-scientific approach should be used to understrand this
behavior of the natural eye -- not a "medical"approach.

Dear prevention minded friends

Otis does not have any medical background and is in no position to give
medical advice.  Please disregard his opinions.

Thank you.

Dear Allen,
You must not read the English language very well.

I said negative refractive state of the natural eye.

You keep on thining "medicine", twist my words,
through your lack of ability to understand simple
English, and then declare that I have made
a "medical" statement.

Jeeze!

While you're correcting his understanding of simple English, note that in
myopia the eye assumes a more _positive_ refractive state.

Dear Mike,

Anyone who understands the design of a control system
knows this.

Build an auto-focused camera with a time-constant of
3/4 second for the accommodation system,
and 100 days for the long-term control system,
and the operation of this sophisticated system
would become obvious.

And yes, the natural eye (primate) is a very sophisticated
system.

Otis

Except it wouldn't have much bearing on real human eyes. Your long-term
control system exists only in your head.

With a "100-day time constant," a 3-diopter myope who removes their glasses
can expect to be a 1-diopter myope in 100 days. It doesn't happen in my
world. Perhaps it happens in yours.

if you're -1.00 to -3.50, and you're over 40 years old, then myopia
isn't that bad.  have you ever considered the positive attributes of
being myopic?  have you ever considered that myopia may be a desirable
trait for presbyopes instead of something to be "cured".

Because when the Bates method fails, the Bates guys can say "you must have
been squinting.

Damnit, I've been wearing my old pair of glasses.  They are my third
strongest prescription.  That is, I have two pairs of glasses that are
stronger than they are.  My vision isn't getting any better.  In fact
whenever I look at the eye charts in my room I am reminded of just how
bad my vision is.  Maybe Bates doesn't work.  Maybe I should just join
the military and get lasik, and screw myopia reversal.  After all
myopia prevention is so much easier anyway.

Who has a working prevention technique?

Please point me to one that works, so I can offer it to my patients.

The Bates book is totally different from the books about Bates.

Guess what: Dr. Bates answered to a precise question that squinting is
LESS injurious for the eyes than wearing glasses.

It is better to squint than to wear glasses.

Again and again, people who write books about Dr. Bates' treatment are
all cheaters.

They have created such a difficult situation for the poor gullible man
who wants to get rid of the glasses, that it becomes almost impossible
to get out of that difficulty.

Anyway, I am always available to offer the true version of Dr. Bates
book and speak about it, sharing experience and motivations.
