Then one of those headbands with fold down lenses of varying

That was the sort of thing I was thinking might have been the most
common reply Bob but I guess it's how to how good other peoples eye are
and what they are doing.

Being able to change the lenses (quickly) helps,

Yes, that was the sort of thing that could soon become tiring, if it
wasn't quick and easy to do.

although there is one I
use 90% of the time.

Which would probably be the same here and so meaning all the others
lenses would become lost. ;-(

For close up stuff, a jeweller's loupe (I have two different
magnifications). I take the glasses off when using them. There is no
loss of binocular vision since the other eye is missing and I'm used to
it. I also wear a monocle quite a bit so it's no strain to use the loupe
for longer periods.

The loupe works for me for inspection but not for actually doing the job
where I need two hands.

This gives me two hands. The loupe stay in as well as the monocle. It's
just practice, and the monocle gives me plenty.

Ah yes, not though of that. ;-)

Is the headband elastic on yours or do you have to fit it

On the flip down lenses? It's a flexible plastic band with a knob you
rotate to loosen/tighten.

Ah, good, I prefer those to elastic for several reasons, primarily
they generally provide a more rigid mount without the tension you
might need to do the same with elastic, especially when flipping
things up and down and moving your head etc.

There are also friction adjustments on the
sides to allow the whole thing to be pushed up and assume the secondary
Steve Fletcher position.

Cool. They sound well thought out.

The lenses flip up too, and you can actually fit
two and combine them - I rarely do that.

Would you be able to find a link to what you use please Bob?
