Read full product description



The Righton original retinoscopy measurement principle achieves an extremely fast auto REF/KER measurement.

Measurement begins immediately after alignment. In addition to the continuous REF/KER measurement, it also performs automatic and continuous peripheral kerator measurements. The distance of the pupil is detected automatically. Each measurement can not only be manually operated, but also set to start by a single joystick operation for high-speed measurement. Includes selective fogging method in addition to normal fogging. With this method, more precise fogging is possible by selecting A2 using the measurement mode key. This type of fogging is useful for analyzing the eyes of patients with unstable eyes, etc.
