youidiota@yahoo.com - 07 Apr 2005 00:15 GMT 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?

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

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

otisbrown@pa.net - 07 Apr 2005 19:01 GMT 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.

youidiota@yahoo.com - 10 Apr 2005 17:27 GMT 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.

otisbrown@pa.net - 10 Apr 2005 19:42 GMT 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.

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

otisbrown@pa.net - 11 Apr 2005 02:48 GMT 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!

otisbrown@pa.net - 11 Apr 2005 03:04 GMT 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 Engineer

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.

retinula@hotmail.com - 11 Apr 2005 00:07 GMT 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.

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.

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.
