How can I know whether I need Bifocals?

Some patients need two different lens prescriptions. Presbyopia is the most common cause, and the main reason some patients need one prescription for near tasks and another for distance tasks. Rather than carrying two pairs of glasses constantly, patients can choose to have those two prescriptions in one pair of glasses, in the form of bifocals or progressive lenses. Simply put, you will need bifocals when you have two different prescriptions and you find it inconvenient to switch back and forth between two pairs of glasses.
