"Lathe turned - A lathe turned contact lens is cut and polished on a CNC lathe.[31] Lathe Turning is #101 of Mass Reducing Operations.[32] The lens starts out as a cylindrical disk held in the jaws of the lathe. The lathe is equipped with an industrial grade diamond as the cutting tool. The CNC Lathe turns at nearly 6000 RPM (revolutions per minute) as the cutter removes the desired amount of material from the inside of the lens. The concave (inner) surface of the lens is then polished with some fine abrasive paste, oil, and a small polyester cottonball turned at high speeds. In order to hold the delicate lens in reverse manner, wax is used as an adhesive. The convex (outer) surface of the lens is thus cut and polished by the same process."

"To inspect the lens, hold the concave side against the scale and look for lathe marks, scratches and edge chips."

: Although I usually support Cinefil-san's answers, in this case I think "Lathe marks" is more meaningful

Thank you! The URL indicated by Cinefil-san has been useful for my research, as I was about to post a response like "lathe turn scratches"...

lathe marks
Lathes are used to cut and grind metals, etc. - lathes are also used for contact lenses.
Here's a website talking about lathe marks on contact lenses.

c) These lathes vut the front and back surface curves along with any peripheral curves, plus the edge shape
d) Lenses are then polished to remove the lathe marks and improve the optics
