Product Description

The Ultramatic RX Master™ Phoroptor® – the first and always the best refracting instrument - continues to be the industry standard after nearly 80 years. Every Phoroptor® has that unmistakable feel of quality. The smooth rotation of the dials. The virtual absence of play in the mechanisms. The precise, solid click of the control knobs. Constant reminders that you’re using the world’s finest refracting instrument. It’s a fit and feels no one can duplicate, any more than they can duplicate the Phoroptor®'s optical quality, accuracy and reliability.
