# XREAL Glasses

XREAL’s products include the XREAL Light Developer Kit, XREAL Light Consumer Kit, and Xreal Air. See below for a brief overview of each headset, the features, and attributes relevant to developers.

* **XREAL Light**: The consumer version of XREAL Light, which is currently selling through its partnered carriers’ retail stores. XREAL Light operates by tethering to an Android smartphone.
* **XREAL Air**: Compared to XREAL Light, XREAL Air is a pared down, yet highly fashionable pair of AR glasses, that pushes the envelope with a form factor that’s wearable and inherently more comfortable.
* **XREAL Light Developer Kit**: The XREAL Light Developer Kit operates by tethering Xreal Light to a proprietary computing pack developed by Xreal.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://xreal.gitbook.io/nrsdk/v1.10.2/nrsdk-fundamentals/xreal-devices/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
