lens

Definition

Used metaphorically for a viewpoint or analytical frame, nearly always in the phrase "through the lens of X." It signals a paper that reinterprets a phenomenon using an existing theory rather than proposing a new method — the contribution is the framing and what it explains. The literal optical sense does appear, but only in work on cameras, image formation, and related imaging problems, where context makes it unmistakable.
