How to add a black bar over eyes in a photo or video
The black bar over the eyes is a familiar look — tabloid photos, medical case studies, screenshots people don't want traced back to them. Here's how to add one, and what it does and doesn't actually hide.
How to add a censor bar over the eyes
The bar over the eyes is Deface's solid colour style, sized as a strip rather than a full-face cover. Automatic face detection covers the whole face by default, so for the classic narrow bar you draw a manual region positioned across the eyes and set it to solid colour — black is traditional, but any colour works.
The same region works across a full video: position it once, and it persists across the frames the same way a detected face would, so you're not repositioning a bar on every frame.
How to do it with Deface
Two approaches, depending on whether you want the classic narrow bar or full-face coverage.
- For the classic bar: import the photo or video, add a manual region, and size it as a narrow rectangle across the eyes rather than the whole face. Set the style to solid colour.
- For full-face coverage instead: let automatic detection find the face and set its style to solid. This covers the whole face rather than just the eye strip.
- Choose the colour. Black is the traditional censor-bar look; any solid colour is available.
- For video, check alignment through the clip. A manual region persists across frames, but reposition it if the face moves enough that the bar drifts off the eyes.
- Export. No watermark on Pro, and metadata is stripped from the file regardless of which style you use.
A bar over just the eyes covers less than it looks like it does. It's a strong visual convention — most people read it instantly as 'this person is being kept anonymous' — but it leaves the nose, mouth, jaw, hairline and ears fully visible, and those are often enough to identify someone who's already known to the viewer, even with the eyes hidden. It reads as redaction, but it isn't full redaction. If the priority is genuinely hiding who someone is rather than following the convention, cover the whole face with solid colour, blur or pixelate instead.
Getting the proportions right
A bar that's too narrow leaves a strip of eyebrow or under-eye showing at the edges, which undercuts the whole point of it. Too wide, and it starts covering the nose or forehead and stops reading as the specific 'eyes only' convention people recognise — at that point you may as well cover the whole face instead. Deface's manual regions have precision size controls for exactly this, so the bar can be sized to sit consistently across the eyes on a given face rather than eyeballing a rectangle.
The same sizing question applies across a group photo — different people's faces are different sizes in the same shot, particularly if some are closer to the camera than others, so a bar sized for one face rarely fits another without adjustment.
Redaction convention, or just the look
The eye bar has two separate origins that have blurred together. In medical and clinical photography it's a real anonymisation convention, used on case-study images where showing the rest of the face is considered acceptable but the eyes specifically are withheld. In tabloids and mugshot-style images it became a visual shorthand for 'this person shouldn't be identified', whether or not it was doing much actual identity protection.
Today it gets used for both reasons at once — sometimes because someone genuinely wants a lighter cover than a full blur, and sometimes purely for the aesthetic, the way a pixelated face reads as 'broadcast TV' regardless of how well it actually obscures anything. Deface doesn't take a position on which reason you have; the solid colour style works the same either way, sized as a full face cover or a narrow bar.
Frequently asked questions
Is there an app that adds a black bar over eyes automatically?
Deface detects the whole face automatically. For the narrow classic eye bar specifically, rather than full-face coverage, use a manual region sized across the eyes and set it to solid colour — that gives you control over exactly how much of the face the bar covers.
Does a bar over the eyes actually hide someone's identity?
Partially. It hides the eyes, which carry a lot of expression and are often the first thing people focus on, but the nose, mouth, jaw and hairline remain visible and can be enough for someone who already knows the person to recognise them. For stronger anonymity, cover the whole face.
Can I add a censor bar to a video, not just a photo?
Yes. Position the manual region once and it persists across the video's frames. Check it periodically through the clip and reposition if the subject moves enough that the bar drifts off the eyes.
Does the censor bar have to be black?
No, black is just the traditional colour. The solid colour style supports any colour.
What's the difference between a censor bar and just blurring the whole face?
A bar covers a smaller, specific strip — usually the eyes — and leaves the rest of the face visible, which reads as a deliberate partial redaction. A full-face blur, pixelate, or solid cover hides considerably more and gives no partial view of the person underneath.
Does adding a censor bar remove the photo's metadata too?
Not by itself — the bar only changes the pixels it covers. Deface strips EXIF, GPS and timestamp data from every export automatically, separately from whichever censor style you use.
