Brock Exercise Notes

leave a comment »

June 27 – afternoon. my first time to Brock in a long long time. I was amazed that I could start out at 12 inches. I was also amazed that when looking softly over the yellow center bead I could get the double image of the rear red bead.

June 28 – afternoon. After a tiring day at work. Again I was able to successfully see the yellow bead at 12″with an “X” through it. But not much took place after that.

July 4 – late morning. More rested. I was able right away to nail yellow Bead it 12 inches. Then briefly, I could back it off to about 18 inches. But this only lasted for a millisecond. Then the whole thing deteriorated.
My other observation is that the right string image is always stronger in front of the bead I am converging on and the left string image is completely strong behind it. This confirms what I felt initially after the BRAO that my brain is vertically aligning upper and lower images from both eyes.

0719brocklog July 9 – walked by my Brock string for the umpteenth time and told myself “Look— it will only take three minutes!” This time I decided not place the yellow bead at a specific place but just grab the first 12” mark near the front green bead and look. I was surprised that I could converge at 21”!

July 10 – late morning, right after massage. Right off the bat I got 25”. Then things got a little wobbly. I got interrupted, but I was able to regroup and see the bead at 20”. I would call that an improvement!

Later that day or the day after, I see my fingers for the first time in 3-D. They were interlaced on my lap, with tips popping out toward me, and looking physically SOLID. It was so awesome I unlaced my right hand and just stoked those solid looking fingertips and then re-laced them once or twice. “So this is what REAL fingers look like.”

It was an almost spiritual experience, making this new connection with my own hands, and so I gave thanks for this new vision I didn’t even ask for. Grace …

July 14 – evening, after a long day on the road. Only managed 15″ convergence and that with only half the X: the right eye image of the string in front and left eye image of string in back of the center bead.
I decided after this poor “X” showing to pick blueberries for visual and emotional therapy. “Fast Cars” from U2’s How to Dismantle an Atomic Bomb played in my head. It fit my anxious mood in a happy U2 sort of way. The tomato plants were begging to be tied in the garden behind me, and the piles of laundry and dirty dishes were waiting inside. It all made my head pop.
But, during that forever time picking, I thought “the whole diplopia experience isn’t needed in real life, so maybe a half an X is ok and a whole X is not the ultimate goal with me.” I know my eyes are converging with just that half an X …

July 16– 2:30 in the afternoon seems to be the best time. I once again was able to see the bead at 19” then things got wobbly. I also could not get myself to see the red bead. But after that, a quick second attempt to see the yellow be succeeded at 24 inches. Doing this more frequently definitely has its advantages.

July 19– 8am just before headed out to my landscaping job, I decide a 10-second “goose” before a visually demanding day would be a good thing. I converged and diverged easily between the near green bead at 8″ and the yellow at 15″ — this is a first.

Seven brief sessions in three weeks, not 21 or more. 3x day is my goal …

Even with only those seven brief sessions, a couple of amazing things happened at my optometry appointment this afternoon. But that’s another blog post!
