Bifocals are glasses that have two different strengths of lenses depending on where you look in the lens. Typically bifocals for [[presbyopia]] and [[myopia]] have the lower section 1-2 [[diopters]] weaker than the upper section, for use during reading.

The EM method uses separate [[differentials]] and [[normalized]] lenses rather than bifocals, making it easier to adjust your [[lens selections]] one at a time.
