Bifocals, also known as multifocal lenses, provide correction for both near and distance vision, as well as astigmatism if needed. These lenses help you see better both close-up and far away when your eyes can no longer change focus due to age/presbyopia.
Bifocal lenses may be a better fit for you if you need two lens powers and do a lot of reading or computer work because they have a wider lens area than progressive lenses.
