1. A modular wearable optics device including:
at least one wearable support element, to be worn by a user;
one or more active optical elements adapted in use to display an image to a user; and
a removable bridging element, selected from a plurality of bridging elements, to position or orientate the one or more active optical elements in a predetermined location based on one or more anthropometric characteristics of the user, wherein the plurality of bridging elements have different shapes and sizes each adapted to locate the one or more active optical elements in a different position or orientation;
wherein the selected bridging element includes an identifier which enables identification of the shape and size of the bridging element by a control system of the one or more active optical elements to thereby adjust one or more convergence parameters of the one or more active optical elements based on the identified shape and size of the selected bridging element.
