Have you thought about trying variable progressive lenses but worried they won’t work for your patients? Maybe your peers won’t stop talking about the ease of dispensing them, or how patient adaptation is practically effortless, with fewer redos.
So, is a variable progressive lens right for you?
The Challenges of Early Progressives
Progressive lenses have evolved significantly since their introduction in 1959, when the biggest challenge facing lens designers was how to provide the desired add power without lines and ledges. Another shortcoming was the inability to create separate right and left designs, resulting in a lens profile that was exactly alike. Most designs were difficult for patients to adapt to due to the narrower working zones. Other issues disrupted the overall binocular focus and peripheral astigmatism, resulting in many patients complaining of swim and blur, and further increased the high non-adapt rates.

Fitting these progressives properly was also a challenge. While opticians typically focused on corridor length, early progressive lens options were based on fitting heights. This caused confusion since corridor length does not equate to fitting height. Only standard long corridor or a compact, short corridor lenses were available. Unfortunately, short corridor designs often delivered poor peripheral acuity, inadequate intermediate utility, excessive image swim, and insufficient reading comfort.

The consequence of limited options, paired with the complexity of fixed-corridor designs frequently resulted in visual compromises:
Free-Form Technology Ushers in a New Era
Thanks to the advent of free-form technology, today’s modern progressives feature asymmetrical designs, providing separate configurations for both right and left lenses. Variable lens technology has conquered many of the limitations of fixed-corridor lenses, offering patients more of what they expect and demand from their progressive lenses: good critical, dynamic and binocular vision in addition to ergonomic utility with regard to comfort and ease of use.
