Very sweet.
That brings back memories of making toric contact lenses. We used a variety of lathes including Hardinge, Levin, Chase, Robertson, and a CNC job called a DAC lathe to cut the spherical surfaces using diamond lathe tools. We would cut a spherical base curve into a hydrophilic blank, crimp the blank in a little Delrin jig, then grind another surface using a diamond coated brass arbor. When the crimp was released, we would have a nice football shaped aspheric surface. I believe we went up to about 6-7 diopters of cylinder once hydrated.
The blank was then mounted on another arbor for machining in an offset collet. The offset would produce a weighted lens that would orient the cylinder on the eye properly. It would then be put into a sphrical collet to cut a little edge lenticulation to reduce the edge thickness for comfort.
