It sounds like you have progressive lenses, and for the first time!  A word
of caution, the vertical position of the lens is critical.  Too high and
you are always looking through the reading portion of the lens (this gives
me a headache).  The only way I can tell for sure that it's happening is to
drive at night on a straight and level stretch of road, with another car
far ahead of me.  I look at its tail lights.  If I have to lower my chin to
see them clearly, I know my lenses are too high.  Looking straight ahead,
those tails lights should be in focus.  If I have to lift my chin very far
to bring them out of focus, the lenses are too low.

The lenses can be raised (or lowered) a millimeter or two by moving the
nose pads closer together (or further apart.  If more adjustment than this
is required, bring the glasses back to the place you bought them.  They
will need to order new lenses and cut them again, at their expense.

I would say I've purchased about eight pair in the last 10 years, and all
but one time the lenses had to be re-cut.  I'm convinced that many of the
people who've tried progressive bifocals and claim they can't wear them are
just victims of poorly fit and poorly adjusted lenses.
