Prism thinning and slab-off

[Randle Tibbs, ABOM]

I've never heard this question before, so can someone help me. When slab-off is present in a pal, can you also do prism thinning?

Yes, slab off is used to reduce the prism difference prism thinning is used to reduce edge thickness. You would have to be careful not to create other issues but it could be done. In most cases slab off is going to add base up to the most minus eye (cut off base down prism, same thing) and prism thinning is going to add base down prism to the lens. They would compliment each other and actually create a more pleasing job, in most cases.
