Automated Binocular Refraction System

The All-In-One* Digital Refraction System

Chronos combines binocular autorefraction and keratometry measurements with binocular subjective testing and visual acuity in a single instrument that occupies a minimal amount of space and optimizes workflow. SightPilot guided refraction software simplifies refraction with a step-by-step guide that gives the operator instructions on how to proceed based on the patient’s response.

Save Time

Binocular testing and a built–in autorefractor that pre–sets the subjective refraction streamlines the process.

Save Space

Chronos combines an autorefractometer, a keratometer, phoropter and acuity testing chart into a single instrument with a compact footprint.


SightPilot software guides the operator through the entire process enabling refractions to be delegated to technicians. 


Perform more refractions without adding exam lanes or trained technicians. 


Multi–function capabilities allow patients to complete the exam without moving to multiple instruments
