Abstract: A measurement system for measuring a position of an eyebox of a virtual image of a pair of spectacles that can be worn on the head of a user can include a holding device for holding the spectacles at a predefined position, and a projection area element, onto which light beams that generate a virtual image can be projected via the first spectacle lens when the spectacles are held by the holding device. The projection area element is arranged at such a position in relation to the first spectacle lens that when the spectacles are held by the holding device, the position of the projection area element at least partially corresponds to the position of a pupil of the user when the user wears the spectacles on the head.

Abstract: A display apparatus which comprises an image module for generating an image, a spectacle-like frame which carries the image module, and wherein the spectacle-like frame comprises a front portion with a nose support, as well as two lateral temples mounted to the front portion. At least one of the temples has shiftably mounted to it a holding element. The holding element comprises a first portion extending downwards from the temple, and a second portion connected with the lower end of the first portion, the second portion extending from the lower end of the first portion in a direction pointing away from the front portion.
