The convex grind arcs down into a convex curve (arcs out) towards the edge. The convex grind is similar to the sabre grind in that it (typically) still has a lot of steel in the middle of the blade, making it the thickest of the three main types of grinds. This puts extra …

Other examples would be rolled and polished edges or faceted edges. The thickness of a plus lens can be minimized by grinding the edge of the lens to a very thin edge. The thickness of a minus lens can be minimized by keeping the center thickness of the lens to a minimum. When we do this, we minimize the saggital value (sag) of the lens
The pair of lenses 12 is fitted against the eyewear frame 10.For each lens 12, the surface facing away from the user when the eyewear is worn is faceted, and the surface facing toward the user when the eyewear is worn is not faceted.The lenses 12 are commercially available and formed by methods commonly known in the art, for example by methods used in crystal manufacturing
The method of both the surface grinding, or fining, and the polishing of a lens are accomplished on the same surfacing machine spindle, precisely reproducing the curvature and alignment from fining to polishing, thereby resulting in improved surface quality and optical properties. The fine grinding and polishing are accomplished using plain water by sequentially securing to and releasing from
Mar 27, 2020 · Page 1 of 2 - Manually grinding a lens - posted in ATM, Optics and DIY Forum: Hello, I’ll start to grind a lens with a photographer friend who wanted after years of photography to make one himself to get a feel of the process.

Mar 27, 2021 · This can cause the split to be asymmetrical. It can be corrected by proceeding to grind each side alternately until the more advanced side is at the desired position relative to the drill point (where the facets meet). Then, grind only the side which needs to move further toward the center by pulling the point width taper out slightly
Nov 18, 2016 · One of your lens elements has a grinding flaw where one surface was ground at two different alignments, i.e., it's faceted.
