Refraction can be measured under various light conditions:
One-touch smooth operation for accurate, automatic measurement of both eyes.
Besides providing an intuitive interface for operation, the RK-F3 can also show the measurement results in various ways. This is very helpful when discussing the examination results with your clients.
Thanks to the small footprint and operation freedom provided by the rotating and tiltable touch screen, the RK-F3m can be a great fit in any room.
By changing the brightness of the fixation target, scotopic, mesopic and photopic conditions can be created. During the measurement, both refraction and pupil size are measured automatically. Scotopic Pupil Size (SPS) measurement can also be done without any refraction measurement.
