Shin Nippon Phoroptor SNP-1

Offered here is a used Shin Nippon Phoroptor SNP-1, a manual refraction unit designed for optometric practices performing routine subjective refraction. It combines sphere, cylinder, and prism adjustments in a single binocular head, allowing the examiner to step through a refraction routine with minimal interruption to patient focus. The construction is straightforward and mechanical, favoring the kind of dependable, low-drift performance that many practitioners look for in an everyday exam lane instrument. The SNP-1 includes the typical accessory lenses needed for near vision testing, plus Risley prisms for phoria and vergence assessment. Dial markings remain legible, and the lens wheels turn with the smooth resistance expected of a well maintained unit, though as a used instrument it does carry some cosmetic wear from years of clinical service. It mounts to a standard phoropter stand or arm, making it a straightforward swap into most existing lane setups. This type of phoropter is a mainstay of vision clinics, optometry offices, and ophthalmology practices that rely on subjective refraction to determine corrective lens prescriptions. It suits practices that want a manual, non-digital solution that is simple to operate and simple to service. The unit is sold as used clinical equipment and represents a practical option for a secondary lane or a budget-conscious primary refraction setup.
