SPHEROPERIMETER Russian patent published in 2018 - IPC A61B3/24 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, namely to ophthalmology. Spheromperimeter contains a screen with light test objects and a positive lens. Spheroperimeter is made in the form of spectacles in which one optical channel is used consisting of a positive aspherical Fresnel lens that is curved along a cylindrical surface and the screen is curved along a cylindrical surface. Radii of curvature of the cylindrical surfaces of the lens and shield are equal, and their symmetry axes are parallel and displaced to the focal length of the lens along the optical axis of the system. Angle of view of the eye is determined with the help of a control system for light test objects built into the spheroperimeter and an electrically connected electronic button. In another embodiment of the spheroperimeter, the control system of the light test objects is electrically connected to the eye oscillation sensor.

EFFECT: application of this group of inventions will reduce the size of the device for use at home.
