AR glasses type visual function inspection device

Abstract

The invention provides an AR glasses type visual function inspection device comprising AR glasses and a mobile terminal. The AR glasses include a frame, AR lenses, a nose pad, a left glasses leg and aright glasses leg. A display box is arranged below the connection between the legs and the frame. The display box includes a micro display, an optical assembly and a driver. An optical assembly adjustment knob is arranged on the surface of the display box. A reflective device is connected to the outer edge of the display box, and the display box is bilaterally symmetrically designed on the AR glasses. A left surveillance camera and a right surveillance camera are installed on the inner sides above the frame. A display controller is contained in the left leg of the glasses. Inspection items are selected by the mobile terminal, an image is sent to the AR glasses for display, and an inspected user can obtain an inspection result by adjusting the AR glasses and performing final calculation bythe mobile terminal. The portable visual function inspection device is small in size and convenient to use, and requires no professional to replace a picture or cover the eyes of the inspected user,and the visual function of the inspected user can be inspected conveniently by simple operation on the inspected user.

Description

technical field [0001] The invention relates to the field of ophthalmic examination, in particular to a device for visual function examination using AR technology. Background technique [0002] Eyes are the most important organ in human senses. About 80% of the knowledge and memory in the brain are acquired through the eyes. Eyes are the most important way for spatial orientation, emotional communication and learning. Therefore, timely eye contact It is necessary to check the function. [0003] The visual functions that people understand mainly include strabismus, amblyopia, stereopsis, and fusion functions. Among them, vision problems such as strabismus and amblyopia have greatly affected people's normal life. Traditional visual function tests can be carried out by means of synoptic machine testing, prism plus cover testing, corneal light reflection method, etc. However, there are different types of defects in existing visual function testing devices: 1. Each instrument ...
