Etymology: "Eyepoints" is simply the plural of "eyepoint," a compound of "eye" and "point." Both parts are plain English words with Old English roots: "eye" comes from Old English "eage," and "point" entered English through Old French from Latin "punctum," meaning a prick or dot. The compound describes a fixed spot in space from which something is seen, which fits the sense of a point of vision. The plural follows the regular English pattern of adding -s to the noun, so each "eyepoint" is a distinct location. In practice, the term is most often used in optics, design, and photography, where designers need to know where the viewer's eyes will sit relative to a screen, lens, or display.

Synonyms: viewpoints, perspectives, vantage points, observation points, viewing positions
