VOLK

Volk Optical pioneered the double-aspheric lens design, a breakthrough
innovation where both surfaces of the lens are aspheric, resulting in
exceptional image quality, clarity, and stereopsis to provide clear views
across the entire lens, all the way to the periphery. The combination of Volk’s
patented double-aspheric optical design in conjunction with the highest
quality glass materials, proprietary anti-reflective (A/R) coating, and timeless
manufacturing and inspection processes developed by Dr. David Volk and
perfected over time, make Volk’s Classic Series lenses the leading standard
in the ophthalmic industry.
