Eyepiece → It is formed from "eye" (from Old English "ēage", meaning the organ of sight) and "piece" (from Old French "piece", meaning a part or section). The word "eyepiece" refers to a part that is associated with the eye, typically used in optical instruments to look through.
Think of the 'eye' as the organ of sight and 'piece' as a part — an eyepiece is a part that you look through with your eye.
