Lens file: Success or failure

It is a fine line dividing, often one that is barely discernable, between genius and madness. Launching a new lens design can sometimes be not dissimilar especially in this new era of free-form progressive designs. Just a little software tweak in the wrong direction can turn positive wearer feedback into negatives.

The most notable benefit of high definition free-form lens design, think of 40,000 hinge points on a 70mm lens surface has been the outcome almost overnight to override 100 years of patent lens design around spherical and toroidal lens curves. Tscherning, Percival, Whitwell, Ostwalt, Wollaston and Tillyer to name but a few. In our modern age of instant expectation the huge significance of free-form lens production has been swiftly passed over without due recognition to its genius. Aberrations that affected lens designs for generations effectively vanished overnight.
