To measure human being’s myopia, farsightedness, astigmatism, vision balance, esotropia, stereo vision, vision fusion and etc.

To check the refractive state of human eye.

Digital Refractor system is a computerized auto refractor used for subjective refraction by regarding the patient’s accommodation power and facilities.

Medizs Digitalized Refractor DR-19 is an automated digital phoropter.Operator can use it to find right eye glasses for patient's vision correction.

The NIDEK REFRACTOR Model RT-3100 is a computerized refractor used for subjective refraction with the NIDEK AUTO REFRACTOMETER (AR), AUTO REF/KERATOMETER (ARK), AUTO REF/ KER/TONOMETER (RKT), or AUTO LENSMETER (LM) via Eye Care card. The RT-3100 includes a refractor head, control box, and relay box. The relay box not only connects the other two units, but also connects the Chart Presenting device or PC. The control box includes the key panel, display, and printer. The display is a touch-screen panel. The control box displays the data and can be used for almost all operations. In addition, the control box operates the refractor head and the connected chart presenting device. It allows the refractor and charts to be controlled together. Normally, the relay box is installed on the system table (not included in the RT-3100 package.)

The NIDEK REFRACTOR Model RT-5100 is a computerized refractor used for subjective refraction in connection with the NIDEK AUTO REFRACTOMETER (AR), AUTO REF/KERATOMETER (ARK), AUTO REF/KER/TONOMETER (RKT), or AUTO LENSMETER (LM). The RT-5100 includes a refractor head, control box, relay box, and printer.

The RT-6100 is a motorized refractor for subjective refraction designed to be connected with other Nidek products such as the Auto Refractometer and/or Lensmeter to import their measurement data. Measurement of refractive errors (spherical power, cylindrical power, and cylinder axis) and binocular visual function testing are performed according to the patient’s response.

The TS-310 is a space-saving automated refraction system that uses a combination of the refractor head of the RT-3100 and a control box.• With the high precision LCD, visual acuity of 5 m as well as near visual acuity of 40 cm can be measured with the same accuracy as a standard refraction using actual distances.• The objective data measured by a NIDEK auto refractometer and the lensometry data measured by a NIDEK lensmeter can be imported and used in this device.

The key technique used in the easyRef Handheld Auto Refractometer is based on principle of Hartmann wave-front sensing.Light is emitted from the light source system inside the device, and then focuses on the bottom of the eye through the spectroscope and exit port, then the light is reflected back to the device,and beam through lens system and received by CCD camera. It is possible to calculate the diopter of the human eye by detecting the offset between the relative calibration light and the spot array formed by the light spot of each sub-aperture.

Manual Refractor is an ophthalmic testing device used to measure an individual’s refractive error and determine their eyeglass prescription.
