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 :-)

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.
