Handheld Digital Auto-refractometer

Handheld Digital Auto-refractometer(AutoSight 900) is a portable vision screener for patients at any age. Its working principle is the refraction of light. Optical rays are focused on a sensor after passing through the eye’s refractive system. The spherical power, cylindrical power, and axis of both eyes can be obtained by digital signal processing.
Features of Handheld Digital Auto-refractometer:

Quick: Automatic and convenient. Press the button at the working distance (35cm/14in) and that’s it. The result will be automatically shown in 5 seconds.
Accurate: Objective measurement of diopter is obtained from optical signal. The result is not affected by various external factors.
Intelligent: Detects multiple eye problems in one measurement including myopia, hyperopia, astigmatism and anisometropia
