I moved to what we in the UK call Varifocals. They're like bifocals in that they cater for both near and far. With these there isn't a dividing line between the two prescription but a smooth transition.

The thing I found with varifocals is there is a narrow band of what's in focus both horizontally and vertically in the reading area. Where those two bands cross is the sweet spot for reading music, or anything else. That means your head has to move to track the score or line of text. I found with one pair of such glasses the sweet spot in each lens wasn't aligned correctly with each eye. It took time to realise what the problem was. Here's what I did to identify the problem. The trick is to close each eye in turn while keeping the head in the same position and while looking at particular notes in the score. If the sweet spot on lenses aren't aligned correctly the notes will appear in focus with one eye but not so with the other. It might take a few tries to see this, especially if youre trying new glasses. I now do this test each time I get new glasses or lenses.

With the unaligned lenses I felt there was something wrong but just couldn't put my finger on it. I didn't get headaches from the bad lenses but some people might.

Having gone through several pairs of varifocals I now switch to single vision glasses for music. I can't see the wrinkles on the conductors' faces so we'll but can make out their expression, which is enough.

You do need to be careful with stairs with this type of glasses. I'm not sure that's entirely due to looking through the reading area. I find the periphery of the lens distorts the field of view. I now find myself misjudging where a ball is in space if playing catch with grandkids. Of course, the distortion happens for stairs as well. This might have something to do with my particular prescription.
