In optics, why is "lens" not "len" used?

Why is "lens" used as a singular not plural?

Not every word in English that ends in -s is plural.

Consider:

gas
bus
canvas
news
atlas

The why is probably because the word lens was taken from the Latin word lens, which is also singular. See Online Etymology. The Oxford English Dictionary says the same.

  • Isn't News a plural of New? A Newspaper contains many articles of new things that happen. "I have good news (many good new things)" Like Sweets (pieces of candy) - a group of things is described by their main adjective in plural. – DraxDomax Jan 26 '16 at 10:41

In optics, lens is a singular noun and its plural is "lenses". A noun that ends with " s" doesn't necessarily mean it's a plural.
