Nidek HandyRef

The Nidek HandyRef refractometer is a device that enables
precise measurement of ocular refraction using the
Pupil Zone Imaging method. It offers a
wide pupil measurement zone, up to 4 mm in diameter,
allowing for more accurate and
subjective refraction measurements.
Additionally, this refractometer is equipped with
SynchroScan technology for stable measurements.
