Progressive Problems
Does the plethora of new progressive products help or hinder the market?
That depends on the dispenser

by Brian Dunleavy

Looking for a progressive lens for a presbyopic patient? A quick look at the Lenses Product Guide published by Frames Data (Jobson Publishing) shows this is hardly an easy decision for today’s dispensers. The guide lists more than 350 variations of progressive designs and brands.

At 23.3 percent of overall lens sales, according to the Jobson Optical Group Database, progressives still lag behind traditional multifocals (24.5 percent). But with presbyopes representing the largest potential eyeglass-wearing population, nearly every lens manufacturer has ensured itself a piece of the pie by developing at least one entry—actually, several entries in most cases—in the progressive market.

A look at the numbers shows why. According to the Jobson Optical Group Database, sales of progressives increased from 2000 to 2001, continuing an upward trend started in 1997. Since that time progressive sales have increased by almost 10 percent. Conversely, sales of bifocals and trifocals, according to Jobson, have declined by 16.5 percent from 1997 to 2001.

Statistics provided by Vision Service Plan (VSP), the largest third-party managed vision care provider in the U.S., demonstrate an even more profound market movement. In 1993, progressives accounted for only 11 percent of the lens products requested by VSP customers. Last year, that number was up to nearly 25 percent.

In speaking with the people who work closely with both lens designs and the dispensers who sell them—wholesale lab executives—however, the problem isn’t the ongoing proliferation of new products per sé, but the refusal by some manufacturers to phase out the older lens lines they replace. The result, they say, is a crowded and confused marketplace—one that includes some of the most important innovations in the history of optical as well as a troubling deficiency in knowledge about them at the dispensary—and, in turn, consumer—level.
“Every lens manufacturer is trying to get their piece of the progressive market and is reluctant to discontinue a design for fear of losing an optician customer committed to that design,” says one wholesale lab executive. “As a result, in my opinion, there are too many progressive products on the market. I can’t imagine that many of the hundred-or-so designs are actually making an impact on the market.”

Of course, lens manufacturers would argue they aren’t just introducing progressive products for the sake of simply bringing something new to market. Research has shown companies have improved upon progressive design and performance significantly in recent years, reducing many of the peripheral distortions that resulted in patient non-adapts with earlier generations of the product. In addition, specialty progressive products—such as “occupational” progressives (see “In the Lens Lab,” page 100), “short-corridor” progressives for smaller frame sizes and “active-wear” progressives with less distortion in the periphery—have successfully adapted progressive technology for new wearer populations. Progressive offerings also come in a full range of materials, with any number of add-ons.
“Some manufacturers have just changed their marketing story or branding, but others have actually redesigned their lenses,” says one lab executive. “There have been several important innovations in recent years, such as short-corridor progressives, occupational lenses for specific tasks and the overall high performance of newer, softer designs.”

Indeed, for the most part, lab executives and dispensers alike applaud manufacturers’ abilities to react to a changing progressive market and develop functional applications for their products. They also see it as a sign of things to come. One development they are anxiously awaiting is the introduction of computer imaging technologies designed to allow labs and other lens processing facilities to match the specific visual needs of individual patients. Most lens manufacturers have systems such as these in development. Some have versions of them in use.

“I believe that is by far the most important development,” says one lab executive. “Designers now have the ability to use recently developed software programs that create the virtual reproduction of vision at various distances. The information can then be converted into manufacturing data, yielding efficient progressive powers over the entire surface of the lens.”

Unfortunately, however, it seems more has been less in some cases. Because of fears that phasing out older designs will cost them customers, many lens manufacturers have a plethora of progressive brands available, with a lot of duplication in function as well as in features and benefits. With dozens of progressives flooding inventory at the lab level (some labs say they offer as many as 80 designs or more), there is a definite “information overload” within the industry.

“As nebulas as it may sound, most professionals gravitate toward those products they perceive offer ease-of-fit, ease-of-adaptation and relative value in a broad range of materials,” adds another. “This perception can also be influenced by a re-enforcing incentive—such as promotional or marketing programs. As a lab, we have to carry a lot of different designs, because we want to be able to address all of our customers’ patients. But there’s not enough discussion at the dispensary level about the differences between designs. One lens does not fit all.”

The solution lab executives offer sounds familiar: education. With so many different progressives on the market, dispensers have an increased responsibility to research all of the available products and pick several brands and designs to meet the needs and wants of their patient bases. Issues to consider include: design, material availability, treatment availability, price selection and ease of fit. Manufacturers may be guilty of muddling the marketplace, but they have also armed dispensers with an arsenal of products that should, ultimately, make it easier for them to move patients away from traditional multifocals and into premium progressive designs.

“It’s a big market with lots of niches for price, availability, private labeling and so on,” says a lab executive. “It’s up to the dispenser to sort through those options and find the best ones for them. If they can cut through the confusion, it’s to their benefit.”
