Persuaded by my wife and kids, I went to the stationary store and bought some art tools, such as oil, painting brushes and sculpting clay. It was not easy to hide my passion for art and love for the art tools and materials.
Sound a little complicated?
In many cases, there is no difference. In other words, traditional surfacing labs have pre-made tools stocked for every prescription imaginable.
For a progressive prescription, a traditional lab must use a semi-finished progressive lens that has the progressive bifocal on one side, then it works the prescription into the side opposite the progressive. A digital lab has the ability to surface the progressive bifocal and the rest of the prescription on the same side.
The ability to use semi-finished single vision lenses means digital labs have more options for lens colors and sizes. Semi-finished progressives limit the pupil distance and lens size of a prescription; digital surfacing removes this limitation almost entirely.
If you are comfortable with standard progressives and your pupil distance works in a specific frame, you will be hard-pressed to find a difference between digitally and traditionally surfaced progressive bifocals.
If you have single vision or use a lined bifocal, there is no difference for you between digitally and traditionally surfaced lenses. In a small number of cases, digital surfacing can create stronger prescriptions than traditional in highly curved wraparound frames.
For this reason and to increase the options for those with pupil distance conflicts, we are partnered with a digital surfacing lab, allowing us to offer digitally surfaced lenses to our customers for an added fee.
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.

However, digital arts is a natural extension of traditional arts due to the digital evolution in human civilization. In an age when everything around us becomes digitalized, the arts are taking this step towards the digital world as well.
