Product Description

Vs-950 Optical Instrument Eye Handheld Auto Refractometer Vision Screener for Sale

VS-950 Vision Screener

 

Features:


Product introduction (main functions):
Ophthalmic optical instruments for eye diopter and visual acuity testing. Diopter and visual acuity testing equipment using infrared eccentric retinal photography technology. The infrared light source is projected onto the retina through the pupil, and the light on the retina is reflected to the pupil area, showing different patterns  under different refractive states. The camera records the pattern and calculates it. Spherical, cylindrical and axial data.

The principle of the vision screening:
Instrument: the typical products of the vision screening instrument adopt the "principle of eccentric photography optometry", which adopts the method of taking eye images at a  certain distance (for example: 100cm), based on the fact that the ametropia of the human eye will lead to different degrees of image display The difference between light and shade, which is  an objective optometry method, can be obtained through measurement and calculation to reflect the index of the refractive state. It can test spherical power, cylinder power and cylinder axis,  and can also measure pupil size and pupil distance.

Significance of clinical application (refractive test results):
Significance of clinical application: Through regular visual inspection and refractive screening, comparative analysis of the data of the tested subjects is carried out to achieve early detection and early intervention.

Advantage:
1. It is easy to carry and does not take up space; 
2. It is cost-effective and has 4G network function. 
3. Real-time haring and transmission screening report; 
4. The detection speed is relatively fast, efficient and convenient for mass screening
