Progressive lenses, sometimes called "no-line bifocals," give you a more youthful appearance by eliminating the visible lines found in bifocal (and trifocal) lenses. But beyond being just a multifocal lens with no visible lines, progressive lenses offer other advantages as well: primarily, the ability to see at all distances, including at arm's length for computer use and up close for reading.

---Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision.
---With progressive lenses, you can look up to see clearly across the room and in the distance. You also can look ahead to view your computer in the intermediate zone and drop your gaze downward to read and do fine work comfortably through the near zone of the lenses.
---It's easy to adapt to today's modern progressive lenses.
Don’t let multi-focal vision cramp your style. You no longer have to be caught peering over bifocals, or switching out two pairs of glasses. With progressive lenses, you can see your entire world in a crisp, clear, seamless way. One pair of eyeglasses can do it all.
Comfortable Vision At More Distances Than Bifocals
Bifocals put you at greater risk for computer vision syndrome (CVS) when using a computer for extended periods. Bifocal wearers have to sit closer to the screen and tilt their heads back to see through the bottom part of their lenses. This unnatural posture can lead to muscle strain, neck pain and other symptoms of CVS.
Progressive lenses more closely mimic the natural vision that you enjoyed before the onset of presbyopia. Instead of providing just two lens powers like bifocals (or three, like trifocals), progressive lenses are true "multifocal" lenses that provide a smooth, seamless progression of many lens powers for clear vision across the room, up close and at all distances in between.
