Unpack your Envision Glasses from the protective case. There is a chance that your Envision Glasses don't have any battery, so make sure to first fully charge it by using the USB to USB-C cable inside the case. Attach the USB-C side to the back of the Envision Glasses and the USB side to your adapter. Keep in mind that charging with a laptop will not always work. By default your Envision Glasses should power on when they're charged. If that is not the case; hold the power button for 6 seconds, which is located on the inside, next to the USB-C port. This will power on your Envision Glasses in about 45 seconds.
If you have already installed the app on your phone, you can skip to step 3.
While your Envision Glasses are still charging, grab your phone and open the Envision app. Now, login to your Envision account or if you don't have an account, sign up for one.
Go to the Glasses tab on the Envision app. This is located next to the Find tab.
Click on Pair Envision Glasses. After that click on Start pairing process and follow the instructions to start pairing your device.
