Acuvue Oasys For Presbyopia Bifocal or Multifocal?!
Question: Acuvue Oasys For Presbyopia Bifocal or Multifocal?
Do you know that if Johnson & Johnson's Acuvue Oasys For Prebyopia contact lens are bifocal (2 focal lenghts) or multi-focal (at least 3 focal lenghts)? I have this question because its label doesn't say whether it is bifocal or multifocal, but its ads says that it provides vision to near, far, and in-between.

If it says near, far and in between , it must be a multifocal .
A bifocal would only have far and near.

all soft lenses for presbyopia are MULTIfocals, not "bi"-focals b/c they use diffractive optics.
