66VT YZ24B Rechargeable Streak Retinoscope | Portable Objective Refraction Instrument

Overview

The 66VT YZ24B Rechargeable Streak Retinoscope is a portable objective refraction instrument used to determine refractive status — myopia, hyperopia and astigmatism — without relying on patient responses. Built around a rechargeable Li-ion battery handle, it is fully cordless in use and projects a sharp, rotatable light streak into the patient's eye. By observing the movement of the retinal reflex at a 0.67-meter working distance, the examiner can accurately assess refractive power and quickly locate the astigmatism axis. The unit recharges on a dedicated charging base with automatic overcharge and over-discharge protection.
