eyeglass
UK: ˈaɪɡlɑːs | US: ˈaɪɡlæs
n. A lens or pair of lenses set in a frame, used to correct or assist defective eyesight.
n. (Historical) A single lens used as a magnifying glass or monocle.
The word "eyeglass" is a straightforward compound of "eye" (Old English ēage, meaning the organ of vision) and "glass" (Old English glæs, referring to transparent material, often silica-based). The term emerged in the late 16th century to describe lenses used for vision correction, reflecting the functional combination of the two components. Over time, "eyeglass" evolved from singular lenses (e.g., monocles) to primarily denote spectacles (paired lenses). The logic is transparent: a tool ("glass") for the "eye."
