RealWear Navigator 520 vs Vuzix M400
Both devices below are described from their manufacturers’ own specification pages. Where a row does not apply to one of them, it says so rather than showing a dash — that is a different statement from “the maker does not publish it”.

Differences you can see
Pictures first, table second. Every chart is computed from the same published fields you can read below it — nothing here is an illustration.
- RealWear Navigator 520
- Vuzix M400
Field of view
Seen from above. The grey area is roughly the human binocular field (~200°).
- RealWear Navigator 52024° (axis not stated)
- Vuzix M40016.8° (axis not stated)
One of these manufacturers publishes an angle without saying which axis it is measured on. Reviewers usually read those figures as diagonal, which would make the real horizontal field narrower than the wedge suggests — so treat the shapes as an impression, not as a ranking.
These angles are NOT measured the same way, so the wedges cannot be read as “this one is wider”. A pair of human eyes covers about 200° for reference.

On sale, and supported
Two different questions: how long you can still buy it new, and how long the manufacturer keeps updating it. The dashed line is the end of a three-year training programme (2029).

Sold and supported are not the same thing. A model can leave the shelves while its maker keeps shipping software to the units you already own — and it can stay on the shelves with no published support commitment at all.

| AnnouncedThe day it was shown, which is not the day it shipped. | 2023-01-03 | 2019-03-21 |
| ReleasedYear the model went on sale. Older is not automatically worse in this category. | 2023 | 2019 |
| AvailabilityWhether you can still order it new today. | On sale | On sale |
| Support endsThe date the manufacturer stops supporting it. Decisive for a fleet you are about to buy. | Support ends: not published by the manufacturer | Support ends: not published by the manufacturer |
| DisplayHow the image is produced. "No display" is a real answer in this category, not a gap. | Micro-LED, one eye | Micro-OLED, one eye |
| Eyes coveredOne eye or both. Over a full shift this is a real difference in fatigue. | One eye | One eye |
| Resolution per eyePixels delivered to each eye. Higher means small text and labels stay readable. | Resolution per eye: not published by the manufacturer | Resolution per eye: not published by the manufacturer |
| Refresh rateImages per second. Higher feels smoother and helps people prone to motion discomfort. | Refresh rate: not published by the manufacturer | Refresh rate: not published by the manufacturer |
| Field of viewHow much of your view the image covers. Bigger is more immersive, not automatically better for work. | 24° | 16.8° |
| Pixel densityPixels per degree of view — the honest way to compare sharpness between a headset and a pair of glasses. Higher is sharper. Only shown where somebody published it; we never compute it ourselves. | Pixel density: not published by the manufacturer | Pixel density: not published by the manufacturer |
| BrightnessIn a plant or outdoors, brightness decides legibility more than resolution does. | Brightness: not published by the manufacturer | 2000 nits |

| Peak pixel densityThe sharpest point, usually the centre of the lens. | Peak pixel density: not published by the manufacturer | Peak pixel density: not published by the manufacturer |
| Subpixel layoutHow the coloured dots sit in a pixel. A stripe looks cleaner on text than PenTile. | RGB stripe · 3 subpixels per pixel | Subpixel layout: not published by the manufacturer |
| Foveated renderingWhether detail is dropped outside where you look, to save performance. | Foveated rendering: not published by the manufacturer | Foveated rendering: not published by the manufacturer |

| Hand trackingWhether bare hands can operate the interface, without a controller or the phone. | No | No |
| Face trackingTracks facial expression — for avatars, not for training scenarios. | No | No |
| Body trackingHow much of the body the device knows about. Estimated legs are not tracked legs. | None | None |
| Controllers includedWhether motion controllers come in the box, or are bought separately — or the device is hands-only. | Controllers included: not published by the manufacturer | Controllers included: not published by the manufacturer |
| Controller modelThe manufacturer's own name for the controller. | Controller model: not published by the manufacturer | Controller model: not published by the manufacturer |
