What is the Vestibulo-Ocular Reflex (VOR)?
The VOR is an automatic eye movement that keeps your vision steady while your head moves. Your eyes move in the opposite direction to your head, so images stay clear.
When the VOR is not working well, such as after a concussion or vestibular injury, head movement can cause blurry vision, dizziness, and trouble focusing.
VORx1 vs VORx2
In both modes your eyes stay on the word. What changes is what the target and your head are doing.

How to Use This Tool
Your goal: keep the word in focus while your head moves.
Pick your mode before you press Start. Use the Exercise Mode buttons below.
For VORx1, choose VORx1. The word stays still. Move your head side to side, or up and down, and keep the word clear.
For VORx2, choose Horizontal, Vertical, or Diagonal. The word moves. Move your head the opposite way.
Press Start.
Say each word out loud. If you can read it, your vision is staying stable.
To change mode partway: settings lock in when the exercise starts. Press Stop, choose the new mode, then press Start again.
