Etymology
Borrowed from Old East Slavic ляца (ljaca, “lentils”), from Proto-Slavic *lęťa. Because of the roundish, flat seeds of this plant, K. Lībietis used the same word (in 1873) to refer also to the structure inside the eye (crystalline lens), as well as its optical equivalent (lens). In this, he followed the model of German Linse.[1]
