The Total Refraction System analyzes massive amounts of visual measurement data and computes “the most comfortable visual acuity value” for the patient automatically. During a near point test, power convergence and power PD automatically makes adjustments. The automatic cross cylinder lens makes simultaneous comparison of cross cylinder charts possible. Automatic refractor has a full data display with high-contrast LCD. Its easy operation with electronic dial and colored key operation allows the doctor to keep looking at the patient while determining the final refraction.
