Do your bifocals have a sharp cutoff or a soft one? I wonder if it makes a
difference either way.

Mine have a soft "Gleitsicht" ( Gliding sight), cut off, ( if you can call
it that), and I have no problems. Some people get used to these in a day or
so, others never do. My optician warned me not to drive home wearing the
first bifocals I got. After a couple of days, this was no longer a problem.
I did not like the sharp cut-offs I had first, and changed them pretty
quickly.
I wear either the clip on flip-up polaroids, or "wraparounds" that fit
completely over my glasses . The ones I have are amber, from "Solar Shield"
and are very good.

When wearing bifocals at the computer, fly-dressing bench etc, you need to
check the position of your monitor, seat height, vice height, etc etc, as
you will otherwise end up with a stiff neck very quickly indeed.
