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.
