Progressive Addition Lenses (No-Line
Multifocals)

As the presbyopic segment of the vision care population
continues to grow, lens manufacturers continue to position
and treat progressive addition lenses (PAL) as their flagship
premium products.
Progressives also referred to as "no-line bifocals".
These lenses are similar to trifocals in that they have
three different prescription areas for near, intermediate,
and distance vision. Progressives differ from bifocals and
trifocals in that the different zones are not separated
by visible lines, but rather offer a natural, "progressive",
transition between the different powers on the lens. This
eliminates the problem of "image jump" associated
with lined multifocals and presents a more attractive appearance.
The upscale Baby Boomers who represent that market growth
are always looking for the best. Hence, today's PALs are
offered (and often packaged) with top-of-the-line features
such as the best lens materials and the finest lens options.
As a result, they continue to make advances on a variety
of fronts. The hottest innovations in progressive addition
lenses are occurring in lens materials, new designs like
short corridors, and Rx customizations like cast-to-prescription
technology. These improvements expand the lenses' capabilities
as well as their appeal to patients.
Ideal Wearers
Progressive addition lenses are ideal for first-time wearers.
Their progressive optics virtually provides the natural
accommodative vision lost due to aging. Of course PALs don't
come without some compromise. Their progressive optics creates
special aberration challenges to distortion and marginal
astigmatism.
With today's new designs and lens materials almost every
patient is a candidate for progressives. To accommodate
today's shallow dimension and smaller frames, short corridor
versions have emerged. Shorter corridor progressives teamed
with softer designs and less distortion, make progressive
addition lenses as close to natural vision as technology
can bring them. Even with "extreme" lifestyle
activities (meaning activities that require a unique use
of one's vision), PALs are a great lens option in nearly
any viewing situation.
Enhanced Reader Progressives
A Profile of Older Americans: 2001 by the Administration
on Aging reveals that 24.3% of householders aged 65 and
older had a computer and 42.6% of this group had Internet
access. This is a good opportunity to consider enhanced
reader progressives. These lenses offer a perfect solution
for any near task enthusiast.
In the next decade, millions of Baby Boomers will greet
their presbyopic years. They'll join the ranks of other
presbyopes who have active lifestyles and want to enjoy
themselves unimpeded by their eyewear. Today's progressive
addition lenses offer that freedom.
