Not necessarily "of course". I would expect the lens to be set to a
distance that gives good vision at some useful distance without needing
to wear glasses. And the two choices are probably infinity so you only
need to wear glasses for reading and other close work (maybe needing a
selection of different glasses for different distances) or else
reading, so you only need to wear glasses for longer distance such as
driving and walking around outside.

When age started making it more difficult to read (and use a computer) I
ordered up some contact lenses that were sort of half way. And although
they did make reading OK, I really couldn't put up with the poorer
distance vision. Seemed most unnatural to me, since I've had corrected
vision from a pretty early age. So soon just accepted I'd have to use a
reading aid. Might be difference for a presenter on TV etc, though. ;-)

Since my contact lenses correct for distance, ready made reading etc specs
are OK. And so cheap I can have enough to leave them were needed. ;-)
