Support for using Gemvision

If you check out Compatibility Page you can find our latest supported devices. You'll also be able to find how and where to download the smart glass app for example

Go to Smart Glasses login, login with your user credentials and scan the generated QR-code with the scanner on you smart glasses.

The preferred method of updating your Vuzix smart glasses is by using the embedded OTA (Over The Air) update mechanism, which require the Vuzix smart glasses to be connected to a stable Wi-Fi network with internet access.

Make sure your smart glasses are plugged into a 1.5 amp USB power source*.
Open the Settings application.
Select the “OTA System Update” option at the bottom of the list.
If an update is available, select “Install”.
Wait for the download, then reboot and install the update.
Once the smart glasses have fully rebooted following the update, your update is complete.
*Do not power-off or interrupt the M300 during the upgrade process the OS may become corrupted! If your OS is corrupted, contact Vuzix Technical Support for assistance.

Have you tried refreshing your browser? If that didn't fix it, check whether the user you need to see has activated their account. Double-check your network or run the network check described on the compatibility page.
