Melody function
For inexperienced patients such as children, the melody function can ease patient anxiety and allow greater cooperation during measurements.

Pupil zone imaging method
The HandyRef-K/HandyRef analyzes a wide area (Max. 4 mm diameter) pupil zone. By measuring the light coming through the pupil zone in a wide area, more accurate measurement data closer to the subjective refraction is now possible.

SynchroScan Technology
The HandyRef-K/HandyRef adopted an excellent measurement method; “SynchroScan Technology”. Measurements start when the alignment starts, and locks in the data when alignment becomes optimal as a measurement value. It provides a more stable measurement value more effectively and efficiently.
