  • Display device for demonstrating optical properties of eyeglasses
    Patent number: 10292581
    Abstract: A display device with a retaining device is disclosed, which can be placed on the head of a user. The display device contains a first image generator, which is secured or can be secured to the retaining device, and a first optical imaging system which is secured to the retaining device and which is designed to image an image generated on a first image plane (E) by the first image generator such that the user can perceive the image with a first eye (LA) when the retaining device is placed on the head of the user. The retaining device supports a first refraction determining optical system which is designed to determine the subjective refraction of the first eye (LA) when the retaining device is placed on the head of the user and/or the first optical imaging system is configured to be variable.
