The new approach, based on nano-structure optics, replaces curved surfaces with a flat substrate etched with millions of microscopic pillars — each just one-thousandth the width of a human hair. These pillars slow light passing through them by varying amounts depending on their height and spacing, precisely controlling the direction of light waves. The result: even 1,500-degree prescriptions can be made just 2mm thick, with material utilization rates exceeding 95%.

In China, being socialist, it's the working class that benefits.

[–] yogthos@lemmy.ml 5 points 1 day ago (1 children)

I have actually, but I don't see how that's relevant to being informed on China.
