It's my understanding that it is the markings on an RX lens which are
different; 1/3 stop more open than the marking shows to compensate for the
prizm viewfinder, for instance at f4 mark, exposure would actually be f4 +
1/3 stop. Maybe you could use it but it would sure be a pain. And if you got
it (or them) mixed in with other non-compensated lenses, it doesn't sound
like fun. Possibly you could make an overlay or something to cover the
original markings. On the other hand, the film that might be ruined could
cost much more than a proper lens.

One thing to observe:
There are two kinds of Bolex lenses: the older ones, and the RX lenses.
The RX lenses contain a compensation in the optical formula for the
beam-splitter in a reflex Bolex.
This means that RX lenses contain an error in the optical formula when
used
on cameras which have mirrors, instead of beamsplitters.
It is not recommended to use a 10mm RX lens on your Eclair.
A non RX lens will work.
