How to use the NeurolignFit device

  • Remove your NeurolignFit device from the box

  • Charge the device with the provided USB cable

  • While the device is charging, scan the QR code in the Quick Start Guide, download the NeurolignFit app, and create an account. Make sure you register with the same email address as you used when purchasing your NeurolignFit device. 

  • Before attaching the device to your phone, make sure your phone is not on silent mode, is set to ‘do not disturb’ and your volume and brightness are turned up

  • Remove your phone case for the duration of the test. This will a) ensure your strap completely attaches your phone to the device and b) will prevent anything from blocking the camera

  • If you wear glasses, remove them for the duration of the test. Images may appear blurry or red tinted. This is normal and will not affect your results

  • Remove the circular cap from the the top of the device; this will make the viewport of the device visible.

  • Turn on the power button

  • Align the phone’s front facing camera with the red filter

  • Use the provided strap to attach your phone to the device

  • Use the same eye consistently to perform the tests

  • If you are left handed, consider adjusting the eye cup to fit your left eye. 



  • Look into the viewport to start performing the tests.

  • You can place your elbow on your chest or on a table for support

  • While you’re performing the tests, cover your other eye (the one not being tested) with your free hand or an eye cover. Do not squint your other eye.

  • Hold your phone in a way that your thumb is free so you can tap or swipe bottom of screen while tests are running
