Have you ever heard of an anastigmat lens?

Yeah, I think it helps correct distortion in images, right?

Root Explanation

Anastigmat → It is formed from "ana-" (meaning back or again) and "stigmat" (from Greek "stigma", meaning mark or point). The word refers to a lens that corrects for distortion, effectively marking or defining the image more clearly again.

Memory Tip

Think of 'back' or 'again' ('ana-') correcting a 'mark' or 'point' ('stigmat') in an image, which helps you remember that an anastigmat lens improves clarity.
