Things have improved markedly since last time. I know that I've said this before, but now it's especially true. I'm experiencing something like stereopsis right now and it's great, and it's amazing to think that it's only going to be greater as motor control increases and as suppression decreases. I should qualify that by saying it's obviously a 'low-resolution' stereopsis since I'm not fusing. If I were fusing, I wouldn't be seeing an extra copy of letters on the screen as I type this.
It's interesting. I've actually experienced my vision improve quite a bit in the past week even though I've taken off several days. But I should say that I have been playing games in stereo 3d a bit extensively. I do believe playing games in stereo 3d can be a good practice for stereopsis. Maybe this means that I shouldn't have been working so hard and so obsessively.
Regardless... I think I discovered the last exercise technique I'm going to have to learn until I fuse and gain full stereopsis. It's that tilting the left and right side of the head toward the light in the light tube, carefully controlling the speed so that I'm just able to maintain a singular view of the glowing circle. It feels like that's it. I've already seen improvement--significant improvement--since a few weeks ago that I discovered it. The idea now is to keep going at it so that I've be able to maintain a singular view of the glowing circle regardless of how quickly I turn my head.
That might be the most important exercise I'm doing right now. I think I'll probably cut down on Columns to five minutes, Bouncy five minutes, saccades five minutes, and tilting light tube for 20 minutes. That's only a 35 minute VT workout, but it's probably better that way... and I'm probably going to take more days off.
