IIRC they showed something similar on tomorrows world a long time ago.

my SLR camera from about 1980-something had an adjustable lens on the
viewfinder,

so the technology has been in commercial use for ages

Presumably that moves the lens forward and back like on binoculars. Not
really practicable for spectacles.

I have varifocals plus a proper set of single prescription lenses set up
for computer use. I add to these clip-ons at +1.5 and +3 diopter for
reading small text and for close-up work.

eg eBay item 172952541377

Doesnt work.

what doesn't work?

That ebay item number.

Nope, the eyes still have compensation available.
All any glasses do is shift the distance at which
the conpensation happens over happens at.

Tell us how you get on. Could be fiddly to adjust "on the fly".

Might be handy for someone like me, who wears different diopters for
differing purposes - one for close, one for TV, another for driving,
but swapping focus would be very fiddely. I would want a push button
select, but not practical. Even better, remote control, or automatic so
they adjust themselves.

Think I will stick with my throwaway £1 glasses :-)

Jim GM4DHJ ... submitted this idea :
pound shop readers are great I have them everywhere for convenience....

Yep, me too. I have expensive prescription glasses in the car for
driving, with a spare £1 pair in the glove box, of the same
prescription, for emergencies.

Sensible way is to use contact lenses to correct any eye defects. Then
various cheap ready mades to cope with old age. ;-)

Reading glasses on a cord round your neck so you don't lose them. I
prefer varifocals which I get on with fine.

Huge cost, though.

My gas permeable contact lenses cost £100 from Specsavers. And non
prescription reading etc specs pennies.
