American Optical AO Phoroptor

This used American Optical AO Phoroptor is one of the most recognizable refracting instruments in the history of optometry, valued for its dependable mechanical design and long service life. Built with the classic AO dial layout, it allows examiners to adjust sphere, cylinder, and axis settings with smooth, tactile precision during subjective refraction exams. Many practices still keep an AO Phoroptor in rotation because of its proven reliability and the familiarity generations of eye care professionals have with its controls. The instrument supports a complete refraction workflow, including distance and near visual acuity testing, phoria and duction assessment, and prism-based diagnostic techniques. Its auxiliary lens wheel accommodates common tools such as the Maddox rod and Risley prism, giving practitioners the flexibility needed for thorough binocular vision evaluation. The dual optical housing and adjustable interpupillary distance mechanism make it easy to fit a wide range of patients comfortably during an exam. As a pre-owned unit, this AO Phoroptor shows signs of its working history but continues to operate reliably for everyday clinical use. It is a practical and cost-effective choice for practices wanting to add a dependable, time-tested refracting instrument to an exam lane, and it remains compatible with the instrument stands and mounting brackets commonly used across optometric offices.
