Among all of the questions we get here at, one of the most common queries definitely involves uncertainties when it comes to lenses. More often than not, people are little bit unsure of the difference between bifocals and progressives. If you often find yourself questioning the difference, read on to learn more.


A bifocal lens is created with two different areas of vision correction, which are divided by a distinct line that sits horizontally across the lens. The top portion of the lens is used for distance, while the bottom portion of the lens is used for closer vision. Our regular bifocals are flat-top 28. This means that the reading portion of the lens is 28-millimeters wide and shaped like a sideways “D.”

Progressive Lenses:

Ever hear of no-line bifocals? Well, this is simply another term for progressives. Like regular bifocals, progressives provide a graduated range of vision that varies from distant to near, all without a line across the lens. Progressive lenses have multiple vision distances, including intermediate, which is perfect for computer usage.

This is a great option for someone who needs the strength of a bifocal but would prefer a seamless appearance on each lens. Other names you may hear for progressive lenses include “no-line trifocals” or “vari-focals.”

While it seems like such a simple distinction, some people are not aware of the difference between bifocals and progressive lenses. Regardless of their difference, both options are excellent for vision correction in a comfortable, effective way.
