Automated Binocular Refraction System

The All-In-One*, Automated Binocular Refraction System with SightPilot Guided Refraction Algorithm

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.

Introducing SightPilot™

SightPilot™ is optimized for understanding and efficient workflow, facilitating delegation when required.
• SightPilot™ simplifies the user interface to provide a step-by-step guide through the refraction process.
• At each step, the operator is given instructions to proceed with the refraction, 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 other technicians. 


Perform more refractions without adding exam lanes or trained technicians. 


Chronos is ADA compliant and easy to adjust.
