Explaining the Difference Between Bifocals and Progressives

Posted by Eric Jaqua on Oct 30, 2015 2:04:24 PM

You probably get a lot of questions in your practice. Many questions come up about the different types of lenses. Many people are asking questions about the difference between bifocal and progressive lenses. If your patients are asking the same questions, here are some suggestions on how to answer that will help eliminate their confusion, and hopefully, provide you with some additional revenue. That’s a win-win!

First, let’s set the stage. Multifocal lenses typically address the needs of your middle-aged to older patients who are starting to feel the effects of aging. Many start to experience presbyopia, which is the gradual loss elasticity of the eyes and the resulting difficulty to focus on objects close up. This condition is very natural, but often annoying, and usually becomes noticeable in people in their early to mid-40s. It may continue to worsen until around age 65.

It’s at this point people need something more than a single vision lens in their prescription eyeglasses. They’re going to need additional magnification in part of the lens to help the eye focus on up-close objects. 

Bifocals

All bifocal lenses work the same. A small portion of the lens has the power to correct your patient’s near vision. Since people usually look down to read or look at object close to them, this area is at the bottom of the lens.

The lens segment (or “seg”) that is devoted to near vision can be in several shapes:

  • Flat-top (sometimes called half-moon, straight top, or D-segment)
  • Full bottom half of a bifocal lens (called “Franklin”, Executive, or E-style)
  • Round

bifocal lens types

Normally, bifocal lenses have a visible line. The line in the round seg is less noticeable than the lines in flat-tops and Executive styles. There is also something called “invisible bifocals” or “no line bifocals” which essentially is a round seg that has been buffed so the line doesn’t show. This can cause optical distortions, however. If an invisible line is desired, it’s usually better to go with progressive lenses.

Progressives

Just like bifocals, progressives give your patients the ability to see far and near. Progressive lenses offer a smooth transition in lens power for distance, intermediate and near distances, without a line.

Since bifocal lenses provide only two powers – one for seeing across the room, and the other for seeing up close – patients may have to “bob” their heads in order to see object in the intermediate range, such as computer screens or items on a grocery store shelf.

Wearers of bifocals have to sit closer to the screen and tilt their heads back to see the screen. Not only is this constant head bobbing and tilting annoying, this unnatural position can lead to muscle strain and neck pain when used for extended periods.

Therefore, it’s easy to justify to your patients the advantages of progressive lenses, especially for those with heavy computer use. Bifocal lenses can be less expensive, but today’s advanced progressive designs offer comfort and functionality that will be worth the investment. Not only will your patients appreciate the difference, they will usually be very happy they spent a little bit more.

Please be aware that IcareLabs sells premium progressive lenses for less than some labs' prices for bifocal lenses.
