What progressive design is Lens Shafters using? It's just marked Lux

Probably some of the same types that other in houses are running. US optical has a lense we can have made with our office initials as the markings..

It is not a matter who has lens that can be engraved. Any lens can be engraved, but you need the equipment for it.

Laser engraving

Laser engraving, or laser marking, is the practice of using lasers to engrave or mark an object. The technique does not involve the use of inks, nor does it involve tool bits which contact the engraving surface and wear out. These properties distinguish laser engraving from alternative engraving or marking technologies where bit heads have to be replaced regularly or inks have to be used.
The impact of laser engraving has been more pronounced for specially-designed "laserable" materials. These include laser-sensitive polymers and novel metal alloys.
The term laser marking is also used as a generic term covering a broad spectrum of surfacing techniques including printing, hot-branding and laser bonding. The machines for laser engraving and laser marking are the same, so that the two terms are usually

The ones that say Lux are their "HD" Lens. They're digitally surfaced, but not sure of the design. Usually only in 1.60-1.67 materials. Also comes in SV.

Maybe the Auto I, that's what Pearle uses for their digital Easyview lenses.
