Abstract

The invention provides a VR visual function inspection device including VR glasses and a mobile terminal. The VR glasses include a VR glasses body and a wearing portion. The VR glasses body includes left and right displays and left and right lenses in the front and left and right eyepieces close to the eyes of an inspected user and located in the rear portion. The positions above the eyepieces close to the eye side are equipped with left and right surveillance cameras. A casing of the VR glasses body further includes a controller, a driver and the like. 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 by the 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 VR 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 ...
