Vision Advantage™

Dynamic Visual Acuity
made accurate


Extend your evaluation

Extend your evaluation with an assessment of vision stability during head movement. Vision Advantage™ provides comprehensive vestibular-ocular reflex (VOR) assessments, helping clinicians plan treatment based on objective data:
  • Head-fixed baseline
  • Visual processing time
  • Loss of acuity from head fixed to head moving
  • Visual acuity scores are given for both sides
  • Quantification of the point just before retinal slip

A user-friendly solution

Vision Advantage™ is equipped with a wireless and lightweight head-worn sensor. As such, head movement is unconstrained, and assessment is easier for the clinician.
  • Compact and lightweight
  • Rechargeable battery – offering hours of active testing
  • USB charging

Patient training

The patient training software uses computerized VOR training to simulate gaze stabilization exercises, with selectable controls for velocity and direction of head movement.

Programmable to progress through varying levels of difficulty, the software can be customized according to patient performance on DVA and GST.

Sensor adjustment

The system is easy to use with its auto-calibration of head movement, ensuring accurate results. Head rotation can be measured in yaw, pitch and roll planes.
