Accurate vision measurement
Considering the refractive error of the patient, the measurement ring is projected on the retina, and is adjusted automatically by Smart Assembly Moving to secure a stable signal. HRK improves the effect of uneven light reflection in normal and cataract eyes with the results being more accurate refractive power data


Rapid guidance to the measurement position
The Aiming Dot quickly guides you to easily find the patient’s visual apex from any position for fast alignment. Reliable refractive power data is then automatically obtained
Color View Mode
Color View Mode allows you to assess the condition of the eyes and the fitting status of contact lenses, and provides corneal curvature values for prescribing contact lenses. Furthermore, it is capable of color display with a Full Color camera and White LED illumination
