Dear Friends,
Subject: Checking BOTH your Snellen and your refractive STATE -- yourself.
We know that the 1914 study (by Bates) was successful. I was told by a
majority-opinion OD that this success did not "count" because the
kids did not measure their refractive STATE, and their STATE did not
change in a positive direction. :
Here is the "tool" to make that critical measurement. It is called,
variously, a "trial lens kit" or a phoropter.
If you a teaching Bates, it would be of value to demonstrate to the
person that his Snellen is clearing and his refraction is moving in
the correct direction as well.
=================
It's basically a phoropter (one of those
"which is better, 1 or 2" machines) that you can keep in your purse or
jacket pocket.
That's 8 plus lenses, 8 minus lenses and a plano lens for each eye,
giving you a whopping 289 possible combinations! (Sorry, no
cylinder/astigmatism lenses.)

"Quickly and easily screen vision with the new handheld I-test
Phoropter Vision Screener. Place the I-test on the face like regular
eye glasses, a patient can adjust lens strength by rotating the dial
to the desired lens strength. Lens range from +4.00 to -4.00 diopter
in 0.50 diopter increments. Each lens also includes its own occluder
and pin hole occluder."
* Tests for myopia, hyperopia, presbyopia, and anisometropia.
* Screen in real life situations
* Adjustable PD, fits everyone
* Folds up for easy storage.
Available in Gold, Gray, and ... Pink (!!)
Get it here for $141.69, with free UPS ground shipping within the
United States.
