Noun
lens (plural lenses or (obsolete) lens)
- An object, usually made of glass, that focuses or defocuses the light that passes through it.
- 2013 July-August, Catherine Clabby, “Focus on Everything”, in American Scientist:
- Not long ago, it was difficult to produce photographs of tiny creatures with every part in focus. That’s because the lenses that are excellent at magnifying tiny subjects produce a narrow depth of field.
-
- A device which focuses or defocuses electron beams.
- (geometry) A convex shape bounded by two circular arcs, joined at their endpoints, the corresponding concave shape being a lune.
- (biology) A genus of the legume family; its bean.
- (anatomy) The transparent crystalline structure in the eye.
- 2013 July-August, Fenella Saunders, “Tiny Lenses See the Big Picture”, in American Scientist:
- The single-imaging optic of the mammalian eye offers some distinct visual advantages. Such lenses can take in photons from a wide range of angles, increasing light sensitivity. They also have high spatial resolution, resolving incoming images in minute detail.
-
- (earth science) A body of rock, ice, or water shaped like a convex lens.
- (by extension, figuratively) A way of looking, literally or figuratively, at something.
- 2004 April 11, Ann Hulbert, “Are the Kids All Right?”, in The New York Times Magazine, page 11:
- If "the public looks at the condition of America's children largely through a negative lens," worries Child Trends […] , "it may be more difficult to […] promote child well-being."

Latin
Etymology 1
Unknown, likely a borrowing from an unidentified source.
Compare Old High German linsa, Lithuanian lęšis, and Old Church Slavonic лѧща (lęšta) sounding too similar for a coincidence, however different enough to prohibit reconstruction of a common PIE protoform. May also be related to Ancient Greek λάθυρος (láthuros).
If ultimately a non-IE loanword, locating the source is virtually impossible because cultivation of lentil was widespread in the region since the Neolithic.
Pronunciation
- (Classical) IPA(key): /lens/, [ɫẽːs]
