DIGITAL GLASSES FOR RESTORING AND EMULATING BINOCULAR VISION Russian patent published in 2023 - IPC A61F9/08 

FIELD: medicine.

SUBSTANCE: digital glasses for restoring and emulating binocular vision contain a body designed to be mounted on a person's head, video cameras with turning and focusing devices, displays displaying a digitized image, a computer processing digital data connected by means of communication to video cameras and displays. Corrective lenses with optical characteristics corresponding to the degree and type of ametropia of the human eye are additionally located in the body of digital glasses at the level of the human eye. In front of the corrective lenses on the optical axis of each eye, achromatic blocks of prisms are additionally located with the possibility of changing the course of optical rays in the range from 0 to 30 degrees relative to the optical axis of the eye. In this case, the blocks of prisms consist of a set of optical prisms, each of which has an independent axis of rotation. Prism blocks are equipped with prism reversal devices. In addition, on the outer surfaces of the optical prisms oriented to the corrective lenses, as part of the prism blocks, a beam-splitting reflective coating is applied, and optical systems are placed between the prism blocks and displays, including objectives, collective lenses and focusing eyepieces, which are installed at an angle relative to the prism blocks so as to reflect the direction of the optical axis of the optical system from the reflecting surfaces of the prisms and align it with the optical axes of the corrective lenses. Moreover, optical systems make it possible to focus the display image falling on the retina of a person in accordance with the distance from the eyes to the object of observation. To register the image of the object of observation on the body of digital glasses, video cameras are placed above the corrective lenses, connected to the devices for their reversal and focusing. A laser pointer is fixed on the body of digital glasses to indicate the center of the field of view on the object of observation. In this case, the devices for turning and focusing video cameras, as well as focusable eyepieces, are controlled by a computer processing digital data.

EFFECT: increase of the contrast, increase of the volume, depth of the image of the observed objects, as well as increase the resolution of the observer's eye.
