Hey Tootsall!
Congrats on the second place win in the Eclipse contest!
Yeah, I can sympathize with the bifocal problem as I'll be 43 this next month. I wore glasses for many years and sure enough, once I got over forty I started having focusing problems. The problem was that I only have one bad eye--very nearsighted in the left eye. The doc said that a clear lens in the right and bifocals in the left would really screw things up. So, I now have a contact in the left eye and reading glasses for up close.
As for the problem of the horn being in the way---have you tried a Dizzy bell horn? I've always thought those would be the way to go for folks that have problems seeing the music on a stand. What I do is what you are doing now---swing right, but when I need to see the second page I swing back to the left.
I also pretty much have the music memorized----take the music home and make your own book. I've done this for years and it works!
