Zero-waste manufacturing of ophthalmic lenses by direct Fluidic Shaping in arbitrary domains

The Takeaway
Traditional lens making is incredibly wasteful, grinding away up to 97% of the material to get the right shape. This new 'Cookie Cutter' method uses mathematical frames to hold liquid in a way that surface tension naturally forms the exact curve needed for a prescription, requiring no grinding or polishing at all.
From the abstract
The conventional manufacturing of ophthalmic lenses is an inefficient subtractive process where up to 97% of the material is discarded through grinding, polishing, and edging. Fluidic Shaping has emerged as a powerful alternative, utilizing surface tension to form optical-quality surfaces. While the approach enabled the creation of ophthalmic lenses without grinding or polishing, it was limited to lenses with a circular or elliptical footprint and still required the wasteful edging process to fi
