To determine the strength of a diopter, if you hold it at an angle you
should be able to see a faint marking indicating its strength. If you wear
corrective lenses and you don't have an OM-3 or OM-4 series body, you will
need a diopter unless the correction you need is -.5, which is built in. So
if you use a -1 diopter, the correction is -1.5. If you have an OM-3 or
OM-4 series body, it has a built in adjustable diopter correction from + 2
to -3. I you need -4, you need a minimum of a -1 and then set the variable
diopter to -3. Personally, I would get the -4 diopter and use the built in
diopter to fine tune the correction. That will also give you the
flexibility of further correction if your eyes change, as they surely will.

Hi
I have two diopters, but only one OM body (OM2) without diopter correction.
They are definitely - (something), but how can I determine how strong they
are? As I understand, you don't need -1 or -2.
