Description

Convertible eye shakes and gathers eye-shade

Technical Field

The utility model relates to an eye-shade technical field, concretely relates to convertible eye shakes and gathers eye-shade.

Background

Nystagmus, called nystagmus for short, is an involuntary rhythmic movement of the eyeball. Peripherical and central pathologies of the vestibular system, as well as certain ocular diseases, can cause ocular shock. The eye shake view inspection collects eye movement videos through an infrared camera, can carry out quantitative analysis on eye shakes, and mainly reflects whether functions of a vestibular peripheral system and a vestibular eye movement passage are intact or not and positions pathological changes. There are four main methods for observing eye shake: naked eye examination, Frenzel ophthalmoscopy, electroseismic mapping (ENG) and seismogram (VNG). Among them, VNG is increasingly popular because it can record and playback eye shake video, has high resolution, and can perform quantitative analysis on vertical and horizontal movements of eye shake. Currently existing VNG devices typically need to be equipped with two cameras and an electrical connection box. During the use process, a doctor induces the eye shake through some specific tests, and can use monocular photography or binocular photography for eye movement video recording in software.

Chinese patent document CN104036256A discloses an eyeball image acquisition device.
