Progressive Lenses Come Of Age

No one likes to advertise their age — especially 40-something adults who start having trouble reading fine print. Thankfully, today's progressive lenses make it impossible for others to tell you've reached "that bifocal age."

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.

Comfortable Vision At More Distances Than Bifocals

Bifocal lenses have only two powers: one for seeing across the room and the other for seeing up close. Objects in between, like a computer screen or items on a grocery store shelf, often remain indistinct with bifocals.

To attempt to see objects at this "intermediate" range clearly, bifocal wearers must bob their heads up and down, alternately looking through the top and then the bottom of their bifocals, to determine which part of the lens works better.

Bifocals also 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.

With progressive lenses, there's no need to bob your head up and down or adopt uncomfortable postures to see your computer screen or other objects at arm's length.

Holding your head in a comfortable position, you can simply look straight ahead to see in the distance, move your eyes slightly downward to view your computer through the intermediate zone and lower your gaze a bit farther to read comfortably up close.

Natural Vision With No "Image Jump"

The visible lines in bifocals and trifocals are points where there's an abrupt change in lens power. When a bifocal or trifocal wearer's line of sight moves across these lines, images suddenly move, or "jump."

Progressive lenses are line-free and have a smooth transition in lens power for clear vision at all distances.

The discomfort caused by this "image jump" can range from being mildly annoying to creating nausea.

In addition, because of the limited number of lens powers in bifocals and trifocals, your depth of focus with these lenses is limited. To be seen clearly, objects must be within a specific range of distances. Objects that are outside the distances covered by the bifocal or trifocal lens powers will be blurred.


Progressive lenses, on the other hand, have a smooth, seamless progression of lens powers for clear vision at all distances. Progressive lenses provide a more natural depth of focus, meaning there's no "image jump."

It's important to note, however, that the first time you wear progressive lenses, you may notice a soft blur in your peripheral vision through the lower half of the lenses, to the right and left of the intermediate and near zones. If this occurs, the sensation typically will go away after a week or two of full-time wear. If it persists, tell your eye doctor or optician. Often, changing to a different progressive lens design will solve the problem.

Progressive Lenses For All Frames And Lifestyles

Because of their advantages over bifocals and trifocals, progressive lenses have become the most popular multifocal lenses for anyone with presbyopia who wears eyeglasses.

And the demand for progressive lenses continues to grow as aging Americans want to continue seeing well and looking good long into their senior years.

This demand has led to a number of recent advances in progressive lens technology. Among them:

Wider zones of clear vision. In early progressive lens designs, the lateral field of view for computer use and reading was somewhat limited. This required wearers to make frequent small head movements and "point their nose" directly at an object to see it clearly.

In today's progressive lenses, the size of the zones for computer use and reading has been increased. And for computer users, special occupational designs greatly expand the intermediate zone for enhanced comfort at the computer.

More comfort for active wear. With early progressive lens designs, first-time wearers frequently noticed soft blur and other peripheral aberrations that could give the sensation of movement or "swim" during quick head turns.

Today's progressive lenses have better optics and fewer peripheral aberrations, making them very comfortable for active wear. Some of the newest high-definition lens designs found in modern progressive lenses are created with the same wavefront-guided technology used in LASIK surgery for crystal-clear optical performance over a wide field of view.

Compatibility with smaller frames. In early progressive lens designs, the power changes within lenses required them to be relatively large. This limited frame selection to larger styles.

Today, many progressive lenses have compact designs specially made for smaller eyeglass frames. With these new designs, wearers with small faces or anyone who wants a smaller, fashionable frame can enjoy all the benefits of progressive lenses.

Better lens materials. Today's progressive lenses are available in all the latest lens materials, making them thinner, lighter and more comfortable than ever before. Progressives made of high-index plastic lens materials can be up to 50 percent thinner than standard plastic bifocals.

For safety eyewear, many brands of progressive lenses are available in lightweight and impact-resistant polycarbonate as well.

Other Options For Progressive Lenses

For the best vision, comfort and appearance, purchase anti-reflective (AR) coating for your progressive lenses.

AR coating virtually eliminates distracting lens reflections that can cause glare when driving at night. It also makes your lenses nearly invisible, for better eye contact with others and a more attractive appearance.

For outdoor wear, many of today's progressive lenses are available in photochromic tints for greater comfort when going in and out of the sun. Some progressive lenses are also available as polarized sunglasses.

Seek Expert Advice For Your Best Lens Choice

With so many progressive lens designs and options available today, the choices can be overwhelming without professional advice.

To make a wise investment and to get the progressive lenses that work best for you, consult with your eye doctor or optician. These experts will be able to recommend a truly customized progressive lens solution for your lifestyle and visual needs. They also can give you helpful tips about how to adapt to your first pair of progressive lenses and how to care for your lenses.
