BERGEON 4422
Eyglasses
For efficient work, the strength
(magnification) of the eyeglass must
be adapted to each individual job.
A reliable magnification should be
used for ordinary work, this avoids
eyestrain!
Eyeglasses with a high degree of
magnification are to be used for
limited periods only.
As you will see, our eyeglasses
are available different strengths;
you can thus choose the one that
suits you best.
As these glasses are inexpensive, we
would advise you to keep a set giving
different degrees of magnification
