1. Download and install the Nebula app on a compatible Android phone, and insert the glasses into the phone to activate and use them automatically.
2. Use a computer to open the activation website https://www.nreal.ai/support/activationGlasses/, insert the glasses into the computer, and activate the glasses according to the instructions on the webpage.
Q: Why do I need to update my glasses when I connect them to my smartphone and open Nebula? Can I cancel the update?
A: In order to improve product experience, Nreal will continually release new firmware versions for the glasses, fix known problems, and function optimization. When the glasses are plugged into the phone, the Nebula app will automatically detect whether the current version of the glasses is up to date, and if not, it will prompt you to update the glasses. Not using the latest firmware version may cause issues with the glasses, please follow the prompts to upgrade for an optimized user experience.
Q: How can I check if my phone is compatible with Nreal Light?
A: We have a list of devices that are compatible with Nreal Air available on our website: Nreal Light Compatibility. If your device is not listed, you may not be able to use Nebula or AR Space. However, if your device has DisplayPort, you will be able to use Air Casting mode. If you are using an iPhone or iPad, you can use Air Casting mode with the Nreal Adapter and original Apple Lightning Digital AV Adapter.
Q: Can I use Nreal Light while wearing my own glasses? What if I am near-sighted or far-sighted?
A: We don’t recommend using Nreal Light with your regular glasses as there will be a distance between the proximity sensor in the center and the wearer equal to the thickness of the glasses frame, making it unstable to use Nreal Light. Nreal Light will recognize if the user is wearing glasses and activate the screen when the distance sensor in the middle of the glasses.
For a better user experience, it is recommended that you visit your optometrist to have your prescription fitted to the prescription lens frame included with your glasses.
Q: Is Nreal Light harmful to your eyesight?
A:
1. Using any electronic product with a screen for extended periods of time may cause eye fatigue;
2. In AR Space mode, the screen distance can be adjusted, and you can adjust it according to your preference;
3. Please also adjust the screen’s brightness to an appropriate level according to the brightness of the current environment to avoid excessive eye fatigue.
We recommend: for every 45 minutes of use, take a 10-minute break before continuing.
Q: Can I use Bluetooth headphones with Nreal Light?
A: Nreal Light has stereo speakers, located on the temples. However, if you wanted a more private audio-visual experience while using your glasses, you can also use Bluetooth earphones and headsets if your glasses are connected to a device that supports Bluetooth.
Q: Can the glasses be charged?
A: Sorry, they can’t. As the glasses are not equipped with batteries, please do not connect your glasses directly to the power supply or a power bank.
Q: Will AR glasses drain my phone battery more quickly?
A: Nreal AR glasses themselves do not have batteries, and require an external power supply during use. Depending on use (Air Casting/AR Space etc.) and the mobile phone itself, the speed of power consumption may vary.
The Adapter has its own battery to supply power to the glasses. Watching long video content like movies through the glasses will consume the mobile phone’s (e.g. iPhone) battery. However, the battery consumption will not be greater watching the same content without the glasses.
