Background

Optometrists perform this test by using a speculum (also known as a retinoscope). The specific detection method comprises the following steps: projecting light emitted by a shadow scope on the fundus of the examinee through a cornea and a pupil; the examiner slightly rotates the speculum; the optometry is to observe the moving direction, speed, form, color and the like of the reflection shadow of the eyeground through an observation hole of a shadow examination mirror; adjusting a test lens in front of the eye to be tested according to the fundus oculi shadow property; when the shadow of the eyeground is still, the 'neutralization' is achieved, and the corrected value of the power of the used testing lens and the detection distance is the full-refraction correction power of the tested eye. In this way, the optometry needs to be performed in a dark room. The used film examination mirror has low price, convenient use, high accuracy if being mastered by skilled people, and can be suitable for children, mentality handicapped, deaf-mute and amblyopia patients, thereby being widely adopted for many years. The examination method can be divided into normal pupil examination (natural pupil) and mydriatic examination (dropping medicine to make the pupil dilated). The specific use of these two methods should be determined according to different ages or the nature of the refractive error. The subject without the interference should use the normal pupil optometry.

The inconvenient rotation regulation of present eye sight optical inspection appearance is observed, can not the fixed eye of efficient, and inconvenient accurate improvement eye sight optical inspection is examined the shadow, and the suitability is lower, and the patient probably moves disorderly, can not hold in the palm the centre gripping of patient face, and intelligent performance is not enough, is difficult to satisfy the demand of present eye sight optical inspection appearance.
