Sounds like the eventual end. Will be learning how to take raw circler optical lenses. As the optical centres do. And build the tools for folks to shape them at home.
Such a project would be a huge advantage to many 3rd world environments. And would likely be about embedding quality glass cutting blades etc into 3d printed frames/mechanisms. Likely from PA. With the ability to embed metal rods and gears where stability, strength is needed.
It’s a guess ut I imagine the issue you have. Is most commercial opticians just see this as less option for them to sell overpriced frames. So agreeing to shape lenes for frames they dont sell. Is just a way to support the end of their profit line.
In the UK, when we started seeing the Chinese companies selling online glasses. We had lots of opticians refusing to give copies of the RX. Or limiting the positioning info they give. As all that part is NHS funded. Laws helped. But without legal force, companies ain’t going to help themselves lose business if it is obvious.
GI Joe never made it to the UK. So unlikely any aged military top brass recognise it.
A bit like Americans naming chocolate bars, after UK names for women’s underwear.
