If your glasses aren't working as they should, sometimes restarting them can help.
The easiest way to restart your XanderGlasses is to power them off, and then power them on again.
To power the glasses off, press and hold the power button on the glasses for at least 10 seconds, until the display turns off completely. Release the button once the display turns off.
Now, turn the glasses on as you normally would, pressing and holding the power button for about 5 seconds, releasing the button as soon as you see the green "V" in the center of the display.
