Digital lens surfacing is mostly relevant to progressive prescription lenses because the major difference between digital and traditional surfacing is digital’s ability to do custom regions within a lens to suit an individual. Sound a little complicated? It can be.
It’s important to note that, just because a lens is made digitally does not automatically mean it is better than a traditionally surfaced lens. In many cases, there is no difference.
Our lab uses advanced surfacing and edging technology, but we do not do digital surfacing. The major reason is that the vast majority of prescriptions do not need digital surfacing. For the small few who do, we have an outside lab available to accommodate their needs.
One of the biggest misconceptions about digital surfacing is that digitally surfaced lenses are always better than traditionally surfaced lenses. This is simply not the case. Because digital surfacing is so much more complex, it is possible to over complicate a relatively simple prescription, creating poorer vision for the wearer. We bow to digital surfacing for its ability to make better progressives for those with smaller pupil distances, but beyond that there is no difference between the lenses our lab produces and the lenses produced by a digital lab.
