It seems like I've made way more progress in two weeks of vision therapy with syntonics than I had with 30 months without. I really thought there was something wrong or ususual about my brain that was the reason for progress to be so slow, like my brain lacked plasticity or myelination.
This session went alright. It only started getting a bit more challenging five minutes into the workout when I started turning up the volume on the lazy eye. It seems as though I've gained quite a bit of conscious control over how much my brain engages that eye. Before I talked about how I used visualization to turn that eye on, but now turning it on is much simpler. It's almost as simple as flexing a muscle. You just think it and it's done.
It reminds me of when I was around ten and I would watch my brother flex his pecs in the mirror (he was 14). I was curious as to how he did that, because I didn't have conscious control over that muscle in isolation. He said that what he did is that he clenched his fist, and then he noticed that if he clenched it hard enough his pec would contract. He would notice the way that the pec felt when that happened and then he would try to replicate that feeling on its own without engaging any other muscle. And it worked. And I tried the same thing and with practice I got the same result.
That said, that feeling of gaining control over a part of your physiology that you previously didn't have control over, is a familiar feeling. The feeling of being able to control the brightness of the light and control the brain's engagement of the lazy eye feels very similar to that feeling of being able to control my pecs. I suspect that learning to control an unusual and untrained part of your physiology might be helpful to people who are trying to gain stereoscopic vision. The process is similar. Granted, I'm sure there's a hell of a lot more wiring that needs doing with vision since sight requires such precise control of the eyeballs.
The saccades exercise was better than ever before. The hardest part is saccading to the extreme bottom right. But today it was very easy. It's not perfect yet, but it's significantly better than it ever was. I suppose that's proof that the issue wasn't mechanical but neurological.
There's another thing I want to mention that I thought about before, but hadn't got around to it. They say that syntonics can cause mood swings and tiredness. I haven't yet experienced either of those things.
