Book Projector for myopia prevention
|
|
|
Assuming too much close work triggers myopia in some children, I am
looking for a projector that can project a book page onto a screen, to
help my son who love reading so much but is starting to develop myopia
at the age of 8. Much like the transparency projector we all know
about, I am talking about the type that project the image of a
non-transparent object like a book page. It has a camera type device
that 'reads' the book and send the signal to be projected.
Does anybody know what is the name for this device and where can I buy
one ? I remember seeing it in a university library many years ago but
can't remember what it is called. |

This is a big assumption, not supported by the research. Avoiding near
work is unlikely to prevent myopia in your son. If he has a near
esophoria (ask his eye doctor), there may be some justification to the
assumption. However, the research suggests that even in the small
group of esophores, avoiding reading will reduce myopia by 10% to 20%,
not prevent it altogether.
Using such a device will destroy the joy of reading for him, it will
become a big production to haul out the projector etc etc. If you
believe that the accommodation associated with near work is causing his
myopia, then simply provide him with +2.00 reading glasses to use for
near work.

Possibly an optical device which places the handheld book at infinity
as far as the eyes can know. Needs prisms and spherical lenses.
(homefully still plus, including cylinder if needed). Could look like
a pair of eyeglasses.
Unfortunately you will probably not be able to find an Eyecare Professional
who will help you with this. It's been tried, and found not to work, they
will say. A mistake with the prisms could get you a wall-eyed kid, I'd guess.
Nobody will touch it.

Dear BuyWheels,
Subject: The SECOND-OPINION for prevention of a child's negative
refractive STATE.
Yours is an excellent idea. The "projector" is called a "View-Graph",
as we called it when we used it.
You will find S.O. ODs who completely support you concept at:
www.chinamyopia.org
And I would sugget reading his site.
There are also M.O. ODs who are hostile to the concept
of prevention -- as you propose it.
I have prepared a PREVENTIVE site (as an engineer) to
help you sort out these issues.
I believe that nearsighedness (a negative refractive STATE)
of the fundamental eye is PREVENTABLE, but with
some obvious difficulties.
The projector idea is excellent.
Best,
Otis

I'm sure there are doctors who will prescribe appropriate lenses in order to
relieve you of $200-$400.
Since you don't like paying for treatments that _do_ work, it's curious why
you advocate treatments with dubious results.

Otis you seem to know what kind of device I am talking about.... do you
have an idea where I can buy one ?
I am not sure if it works, and I don't think any clinical trials has
been conducted to prove that it does not work either.... what I know
as someone with -8.0 myopia is that I am at a much higher risk in
developing floaters, glaucoma, retinal detachment, macular degeneration
etc when compare with someone without myopia.... so whatever I can do
for my son I will give it a shot, even if it only helps slow the
progression of myopia somehow I consider that good investment.
Thanks.

That's about cooking up a pair of eyeglasses for a kid, where there's prism
and sphere to fool the kid's eyes into thinking that the book he holds is at
infinity or at some far-away distance. And, after that, checked to see if those
eyeglasses were used appropriately, before announcing any negative results?
..
Have you ever done it?
Do you know anyone who has?
And Otis, you keep out of this! This is a bit more subtle than "The Plus".

That is another thing entirely. I don't like paying for eyeglasses that do not
do the job they are supposed optically as well as not fitting my fat face,
especially when I have to pay more than once for the same incidence
(possibly on account that eyecare professionals, having discovered
that contact customers are constant patients, now equivocate eyeglass
scripts and bias frames to develop similar levels of aftermarket potential.)

Actually, I think you can still buy such a contraption, called the
"myopter".
http://www.i-care.net/myopter.htm
I don't think it ever was very successful because who would wear it?

How about a thing like this:
http://szjulong.en.alibaba.com/product/50068720/50313337/Digital_Visual_Presenters/Video_Overhead_Projector.html
OR http://tinyurl.com/n8kac
Also, bear in mind that any low-vision type viewer (CCTV or similar)
COULD work for your purposes. Your son could simply sit far back from
the screen.
http://www.lowvisionsolutions.com/Topaz/adwords.html
http://www.enhancedvision.com/merlin_family.php
http://www.enhancedvision.com/flipper_family.php
etc. You can Google for "low vision" and devices, aids, products,
etc.
Good luck! |

Google on the word episcoop.
Having mentioned the name off the device I should strongly recomment to
avoid the use of it.
You need a somewhat dark room to see the projected book on the wall.
Your son already being nearsighted probebly shall squint to see the
letters on the wall more sharply.
TMHO your idea is a bad one.

I thought research did support that near work was likely to cause
(contribute to the likelihood of developing) myopia, only that plus
lenses and/or prisms didn't help to stop it. ?
For a while my mind went down this path, only with the idea being to
project the computer onto a wall rather than use a monitor.
