If Steam Frame eye tracking appears to be broken, first identify which function has failed. Steam Frame uses two inward-facing cameras for its own eye tracking and foveated streaming. A separate problem occurs when a streamed PC application receives no gaze or eye-openness data through Steam Link, OpenXR, or OSC. Those are different data paths, so the fix for one does not prove anything about the other.
Use the symptom guide below, check only the software requirement that matches the feature you are using, and avoid assuming that a missing PC data stream means the headset cameras have failed.
Identify the failure before changing settings
Steam Frame’s eye-tracking cameras serve the headset’s internal rendering pipeline. Valve describes the resulting low-latency eye data as a way to steer detail toward the point you are looking at during foveated streaming. That is not the same as exporting gaze information to a Windows or Linux application.
Start by deciding which row best matches what you see:

| What you observe | Data path involved | First checks |
|---|---|---|
| Image detail does not appear to follow your gaze, or the streamed image behaves as though foveation is not responding. | Steam Frame’s internal eye tracking and the headset’s foveated-streaming pipeline. | Confirm the headset is worn normally, check that the inward camera area is unobstructed, and note whether the behavior is present throughout the headset experience. |
| A particular streamed PC application shows no gaze input. | Steam Link sharing plus the interface that application consumes, such as OpenXR eye gaze or OSC. | Check eye-data sharing in Steam Link settings and verify that the application supports the same interface. |
| No application receives data, but only when using an OSC-based feature. | SteamVR’s OSC exposure of Steam Frame eye-openness information. | Check the SteamVR and SteamOS versions against Valve’s dated requirement for that feature. |
| One application fails while another receives data. | Usually an application integration, permission, or interface mismatch rather than proof of a headset-camera fault. | Compare the working and failing applications’ supported interfaces and settings. |
Do not use the presence or absence of a visible foveated effect as a test of whether a PC application is receiving gaze data. The headset can be tracking internally while an application integration is disabled or unsupported.
Also note whether the symptom is reproducible. A one-time interruption after launching Steam Link is different from a failure that occurs in every session. Record whether restarting the stream changes anything, but do not treat a restart as a calibration or repair procedure.
How Steam Frame’s cameras differ
Valve lists two cameras inside the headset for eye tracking. It separately lists four outward-facing monochrome cameras for headset and controller tracking, plus infrared illuminators intended to support tracking in dark environments. The outward-facing cameras are not the eye-tracking cameras.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsThis distinction matters when diagnosing a blocked or dirty camera. Looking at the external tracking cameras, controller tracking, or room-tracking behavior cannot by itself confirm that the two inward cameras are working. Conversely, a problem with an outward camera does not establish that eye tracking has failed.
Valve’s product description connects the inward-camera data to foveated streaming: image detail is directed toward the user’s gaze so the system can allocate more detail where it is needed. That description explains the purpose of the feature, but it does not publish a user-facing calibration sequence, reset command, sensor test, or camera-repair procedure.
The infrared illuminators mentioned in the hardware description should not be mistaken for an additional eye sensor. They are associated with the outward tracking system and dark-environment tracking. A room-tracking change therefore does not tell you whether the interior eye cameras are obstructed or functioning.
If foveated streaming appears not to follow your eyes
1. Check fit and the camera view without disassembling anything
Wear the headset in its normal viewing position and make sure the area around the inward-facing cameras is not covered by a face covering, loose material, a damaged gasket, or another obstruction. Check the lens and surrounding interior visually under normal lighting. Do not insert tools, touch the camera modules, or open the headset.
Keep the check limited to visible conditions. Do not infer that a particular lens insert, accessory, or cleaning product will correct tracking: Valve lists prescription inserts and other accessories, but does not identify them as eye-tracking fixes. There is no supported purchase or known accessory cost that can be presented as a remedy for this fault.

This is a cautious physical check, not an official Valve calibration instruction. Valve’s published hardware information identifies the cameras but does not say that a particular cleaning method, alignment adjustment, or user calibration will restore tracking.
2. Separate a rendering symptom from an eye-data symptom
Ask whether the complaint is about image allocation inside the headset or about a separate application. If the concern is that a PC application cannot read gaze, skip to the Steam Link and application-path checks rather than treating foveated rendering as the test.
If the concern remains limited to the headset’s visual behavior after the fit and obstruction check, record the exact software versions and the circumstances in which it occurs. Note whether it happens in every streamed experience or only one title, and whether moving your head or changing room lighting changes the symptom. These observations help support staff distinguish a rendering-path problem from a tracking-path problem, but they do not replace a Valve diagnostic.
3. Compare repeatable conditions
Run the same short test more than once, using the same headset position and stream. Write down whether the effect is absent immediately, disappears after movement, or changes between sessions. If the issue appears only in one streamed title, that title’s rendering or integration is a more specific lead than a general camera failure. If it appears across all foveated-streaming experiences, report that broader scope.
If a streamed PC application receives no gaze data
Check Steam Link’s sharing setting
Valve’s Steam Link announcement says eye-gaze information may be passed through OpenXR using XR_EXT_eye_gaze_interaction when the feature is enabled in Steam Link settings. Open Steam Link’s settings on the device used for streaming and look for the eye-data or eye-gaze sharing control. The exact label can vary with the software version; the important question is whether sharing is enabled for the current streaming session.
Changing this setting addresses the transmission path only. It does not recalibrate the headset’s cameras, and enabling it cannot make an application that lacks OpenXR eye-gaze support consume the data. Recheck the setting after reconnecting if your setup uses separate host and client sessions, because the relevant control must apply to the active stream.
Confirm the application’s interface
Check the application’s documentation or input settings to determine which interface it supports. OpenXR eye gaze and OSC eye-openness are not interchangeable:
- OpenXR eye gaze: the Steam Link announcement describes eye-gaze information exposed through
XR_EXT_eye_gaze_interaction. The application must use an OpenXR implementation and request or support that extension. - OSC eye-openness: Valve’s SteamVR 2.18.2 beta announcement describes Steam Frame eye-openness information exposed via OSC. Eye openness is a different signal from a gaze direction or gaze point.
An application can therefore fail to show gaze input while Steam Link is sharing data correctly if it expects a different interface, does not enable the relevant extension, or only supports another eye signal.

Do not assume that an application’s generic “eye tracking” label identifies its transport. Confirm whether it expects an OpenXR extension, OSC messages, or another integration. If the documentation does not name a supported interface, mark the result as “unsupported or unknown” rather than diagnosing a camera failure.
Use the one-app versus all-apps test
Test a second application that explicitly supports the same interface, if one is available in your setup. A failure isolated to one application points toward that application’s integration or settings. A failure across applications that use the same path makes a Steam Link, SteamVR, operating-system, or headset-side issue more plausible, although it still does not identify a failed camera.
Write down which applications were tested, which interface each one uses, and whether the result was “data present,” “no data,” or “application does not support the interface.” That record is more useful than a general statement that eye tracking is broken.
Version requirements for OSC eye-openness data
Valve’s SteamVR 2.18.2 beta announcement, dated October 1, 2026, states that Steam Frame eye-openness information is exposed through OSC on SteamOS 0.4.3 or higher. The announcement identified SteamOS 0.4.3 as being on the OS Beta branch at that time.
Apply that requirement only when all of the following are true:
- You are trying to read eye-openness information, not merely use the headset’s internal foveated streaming.
- Your software path is OSC through SteamVR.
- Your SteamVR build and SteamOS channel match the versions covered by Valve’s announcement.
This is not a blanket minimum version for every form of Steam Frame eye tracking. It does not establish that SteamOS 0.4.3 is required for the headset’s internal foveated rendering, and it does not make OSC eye-openness equivalent to OpenXR gaze.
Because the announcement was a beta-channel note, check the current SteamVR and SteamOS release notes before changing branches. A version that was required or available in beta on October 1, 2026 may have moved, changed, or reached stable status later. Do not switch to a beta branch solely on the assumption that it will fix every eye-tracking symptom.

Check the complete data path, not just the headset
For a PC application, eye information has to travel through several components. A useful map is:

- Steam Frame sensing: the two inward-facing cameras collect the headset’s eye signal.
- Streaming transport: Steam Link must be allowed to share the relevant eye information when that path requires an opt-in setting.
- Runtime interface: the receiving side must expose the signal through the interface being used, such as OpenXR eye gaze or OSC eye-openness.
- Application integration: the PC application must support that interface and actually request or listen for the signal.
A break at any later stage can look like “eye tracking is not working” even when the headset’s internal tracking is functioning. Record the first stage at which you can demonstrate a failure. For example, “Steam Link sharing enabled, OpenXR application reports no XR_EXT_eye_gaze_interaction data” is a more actionable report than “the cameras do nothing.”
Use the same interface when comparing systems. A working OSC consumer cannot validate an OpenXR extension, and an OpenXR test cannot prove that OSC eye-openness is being emitted. This is why a cross-application comparison is useful only when the applications consume the same signal.
What you can safely inspect—and what you cannot conclude
Reasonable visual checks
- Confirm the headset sits in its normal position during the test.
- Inspect the inward camera area for an obvious obstruction.
- Compare behavior across more than one supported application or stream when the complaint concerns PC data.
- Record whether the issue affects foveated rendering, OpenXR gaze, OSC eye-openness, or more than one of these.
- Check whether the symptom follows the headset across supported sessions, rather than assuming a single application’s result represents the hardware.
Claims the published material does not support
- There is no published Valve procedure in the material reviewed here for user calibration of Steam Frame eye tracking.
- There is no published button sequence or software command supplied here for resetting the eye-tracking system.
- There is no published user test that confirms a dead eye camera, and no device-opening or camera-replacement procedure.
- Valve’s listing of prescription inserts and other accessories does not identify them as eye-tracking fixes. Buying an insert or accessory is not an established remedy for a tracking fault.
- No stated price, replacement-part program, or accessory purchase is established as a solution. Avoid spending money before Valve documents a device-specific remedy.
If a support page later supplies a device-specific calibration or service process, follow that current Valve documentation rather than substituting generic headset instructions.

When the checks above do not isolate the failure, create a concise reproduction record:
- Write down the Steam Frame software, SteamVR, Steam Link, and SteamOS versions, including whether each is stable or beta.
- State whether the symptom is missing foveated detail, missing OpenXR gaze, missing OSC eye-openness, or more than one.
- List the application or applications tested and the interface each one is expected to use.
- Describe the Steam Link eye-data sharing setting at the time of the test.
- Note whether the problem occurs in one application or across multiple applications using the same path.
- Record the exact steps that reproduce the issue and any visible error message.
- State whether the headset fit and inward-camera area were visually checked, without claiming that this proves sensor health.
For problems that occur in SteamVR or during streaming, Valve’s SteamVR announcement directs users to the SteamVR Bug Report forum and asks them to include a SteamVR System Report if possible. Include the report with the reproduction details, while avoiding unrelated personal information. This is a software-support route, not a promise that the report will identify a hardware failure immediately.

Treating every failure as a camera fault
A PC application can miss gaze data because sharing is disabled or because the application expects a different interface. Diagnose the transport and application path before concluding that the inward cameras are defective.
Using the OSC requirement for the wrong feature
The SteamVR 2.18.2 beta note is specifically about Steam Frame eye-openness information over OSC and SteamOS 0.4.3 or higher. Applying that requirement to all eye tracking can lead to an unnecessary operating-system change and still leave an OpenXR integration problem unresolved.

Opening the headset or buying accessories
The public Valve material covered here does not authorize a user repair, camera replacement, or accessory-based correction. Do not open the headset or treat prescription inserts and accessory kits as a documented tracking solution.
Changing beta channels without a matching symptom
A beta requirement is relevant only to the feature and interface named in the announcement. Moving SteamOS or SteamVR to a beta branch when the problem is foveated rendering or an OpenXR application mismatch adds another variable without establishing a fix.
Decision checklist
- Foveated image behavior only: check normal fit and unobstructed inward cameras, document the visual symptom, and seek current Valve device support if it persists.
- One PC app receives no gaze: verify Steam Link sharing, identify whether the app uses OpenXR eye gaze or OSC, and check that the app supports that interface.
- All OSC eye-openness consumers fail: compare SteamVR and SteamOS versions with Valve’s October 1, 2026 beta requirement of SteamOS 0.4.3 or higher, remembering the beta-channel qualification.
- Several SteamVR or streaming paths fail: capture versions and reproduction steps, then use the SteamVR Bug Report forum with a SteamVR System Report if possible.
The key diagnostic boundary is the location of the failure: inside Steam Frame’s foveated-streaming pipeline, in Steam Link’s sharing path, in the OpenXR or OSC interface, or inside one application’s integration. Keeping those paths separate prevents an unsupported calibration or repair guess from replacing the evidence you need for a proper fix.

Frequently Asked Questions
Does Steam Frame eye tracking require SteamOS 0.4.3?
Valve’s October 1, 2026 SteamVR 2.18.2 beta note specifies SteamOS 0.4.3 or higher for Steam Frame eye-openness information exposed through OSC. It does not state that this version is required for every headset eye-tracking function or for internal foveated streaming.
Why does foveated streaming work while my PC app gets no gaze data?
Internal foveated streaming and PC application data use different paths. Steam Link sharing may be disabled, or the application may not support the OpenXR eye-gaze extension or the OSC signal you are testing.
Are the four external cameras the eye-tracking cameras?
No. Valve describes two interior cameras for eye tracking. The four outward-facing monochrome cameras are for headset and controller tracking, with infrared illuminators for tracking in dark environments.
Can I recalibrate or reset Steam Frame eye tracking?
The published Valve material does not provide a user calibration sequence, reset command, sensor test, or camera-repair procedure. Check current Valve support documentation rather than applying generic headset instructions.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
What should I report if the problem continues?
Record versions and stable/beta channels, the exact symptom, applications and interfaces tested, Steam Link sharing status, reproduction steps, and errors. For SteamVR or streaming failures, Valve recommends the SteamVR Bug Report forum and a SteamVR System Report if possible.
Should I buy prescription inserts or another accessory to fix tracking?
No documented Valve material identifies those accessories as a remedy for eye-tracking faults. Do not spend money on an insert or accessory as a troubleshooting step unless Valve later publishes a device-specific recommendation.
The Bottom Line
First decide whether the failure is internal foveated streaming or missing data in a streamed PC application. Check the inward cameras and fit without opening the headset, verify Steam Link sharing and the application’s OpenXR or OSC interface, and apply the SteamOS 0.4.3 requirement only to OSC eye-openness data. If the issue persists, document the exact path and use Valve’s SteamVR reporting route rather than guessing at calibration, repairs, or accessories.
