Etymology: "Eyelessness" is about as transparent as English compounds get: it is simply "eyeless" with the suffix "-ness" attached. "Eyeless" itself is built from "eye" and the suffix "-less", meaning "without", so the noun names the state of being without eyes, whether that is a congenital condition in a creature or the absence of sight-organs in a species. The suffix "-ness" is an old and productive Germanic one, descended from Old English "-nes" and used to turn adjectives into abstract nouns of quality or state. Pairing it with "eyeless" follows the same pattern as "kindness" from "kind" or "wilderness" from "wild", so the word needed no special coinage to be understood.
