I shut my right eye, and focus for the left, then I shut my left eye and
adjust the diopter for my right. Usually the dipoter setting ends up
close to zero. I have actually become quite quick at diopter setting,
as my first binoculars were crappy ones that required different settings
for different distances!
The problem is that every now and then I find it's wrong (but hasn't
slipped). So I go through the procedure and fix it. The setting ends
up a bit to the right of zero. Then a little while later I have to put
it back again. From this I deduce that one lens moves a little on my
eye, then moves back. I will experiment with blinking to try to fix it
instead.
