Nidek Phoropter RT-500

This is a used Nidek RT-500 phoropter, a manual refraction instrument used by optometrists and ophthalmologists to determine a patient's precise eyeglass or contact lens prescription. The unit allows the examiner to dial through a full range of spherical and cylindrical lens powers along with prism and axis adjustments while the patient views an eye chart, forming the backbone of the subjective refraction exam. It has been tested for smooth mechanical operation and is ready to be placed back into clinical service. Built with the dual-eyepiece housing familiar to most refraction lanes, the RT-500 includes standard auxiliary lenses such as Jackson cross cylinders, Risley prisms, and red-green filters, giving practitioners the tools needed for a thorough refractive workup. Its manual control design appeals to clinics that prefer traditional refraction workflows or that are equipping a secondary exam lane at a lower cost than a fully automated system. The instrument mounts on a standard refraction stand or wall arm, making it compatible with most existing exam room setups. As a pre-owned unit, this RT-500 carries typical cosmetic wear from clinical use but functions reliably for everyday refraction work. It represents a solid, budget-conscious option for optometry practices, teaching clinics, or vision screening programs that need a dependable manual phoropter.
