The light tube wasn't particularly interesting. It wasn't as stressful as the other day, but it's still a pretty good workout for the most part.
Special Tetris went well. I have been experimenting with different ways of playing it. It seems when I look at it dead straight and when there's a falling pieces somewhere in the middle of the screen, that requires a lot of effort to track. I've also experimented with looking at the screen obliquely in hopes to make the game more challenging. I notice more esotropia when I am looking at the falling pieces from higher up on the screen. That may be a place to give more future focus. Regardless, the game is still challenging, and I notice a different feel in my eyes as the timer continues. The movement begins to feel more rigid, if that makes sense. I am looking forward to stereopsis.
