well, first you could consider any of our ICES-PEMF to be best described as: ultra-high efficiency, ultra-low power… but don’t get confused that “ultra-low power” is the same thing as “crappy ineffective low power junk”. The explanation is deep in the math, but a simple ratio might suffice:
Our devices are about 500 times more efficient than typical PEMF systems, meaning that they get the same biological effect with only 1/500th of the electromagnetic power.
But our devices typically use something like 1/100th of the power of a typical PEMF system.
So, if you work the math, calculate the ratios, what you end up discovering is that our ICES-PEMF systems consume and emit only about 1% of the power, but are about 5 times more powerful when you consider their actual biological effects. Don’t worry if you do not understand this if you do not have a degree in physics or engineering. The bottom line is that comparing power for PEMF systems tells you basically ZERO about how well they actually work unless you factor in a lot of other calculations. So, my advice to you is to stop thinking about comparing power, because it will never ever** tell you anything real or useful. I can prove this to you, but only if you have the technical background to understand the math and engineering and biology facts. Otherwise, please just take my word for it.
** there is one valuable exception: PEMF generally works less well if you apply to much power. Very few people believe me until they prove it to themselves, but about 90% of the time when ICES-PEMF does not work well for someone, it turns out that they are using too much power, and if they will just dial it down a few notches, it will be much more effective for them. Many people seem to have a huge psychological blockage to this truth, so they continue to suffer needlessly, sometimes for many months, until finally they are willing to try less intensity. Then, surprisingly, about 9 times out of 10, ICES-PEMF actually starts working better for them.
Now, to answer your very reasonable question about which of our systems to use for applications related to the eye:
I suggest the M1 rather than the A9. This is because for many people eye tissue is very sensitive to PEMF intensity, and the M1 allows you to adjust the intensity to a very low level. You will need to experiment to see what works for you as an individual, so I suggest you start with very low intensity (try starting at level 3 or 4) to see if you respond well. If not, then try increasing intensity in small increments.
You can probably use it as long as you want, but I suggest you start with short sessions, maybe 5 to 10 minutes, at low intensity as described above, and work up from there as you become more familiar with your individual response to ICES-PEMF.
