What the term actually describes
Orbital vector compares how far the eye socket bone (the infraorbital rim) sits relative to the front of the eye itself, viewed from the side:
- Positive vector — the bone and surrounding soft tissue sit forward of the eye.
- Negative vector — the eye sits forward of the bone, reading as more sunken or hollow.
It's a depth relationship between two structures, not a distance and not a size in absolute units — and soft tissue at the rim moves it as much as the bone underneath does, which is part of why forum threads on the term rarely agree on how to self-assess it from a photo.
Why a front-facing camera can't read it
The relationship orbital vector describes sits on the depth axis of the face — the same axis a straight-on camera view compresses the most:
- A full-frontal shot flattens the socket-to-eye relationship into the outline of the face, where the actual forward/back offset isn't visible.
- Reading it requires a genuine side profile, where the rim and the front of the eye can be compared against each other in depth.
That's a different camera-setup problem from the pitch/roll/turn sensitivities covered in the full breakdown of why face-rating scores swing between scans — those are about holding a front-facing angle steady; this is about needing a different angle entirely.
Where this fits next to what Mogalytics actually reads
Mogalytics does not compute or display a separate orbital vector number. Its six-measurement composite reads live from a front-facing camera feed, and the closest measurement by location is:
- Canthal tilt — the only other eye-region measurement Mogalytics reads live, an eye-line angle rather than a socket-depth relationship.
Canthal tilt and orbital vector both concern the eye region, but they're not the same measurement — one is an angle read frontally, the other is a forward/back offset read in profile. Mogalytics makes no claim of parity between the two, or with any other site's specific orbital vector assessment.
Related reads
Orbital vector sits next to two of the six measurements Mogalytics tracks. If you're auditing the rest:
- Canthal tilt — the closest camera-read analog by region, sensitive to head roll rather than profile depth.
- Midface ratio — the other measurement anchored to the eye line, distorted by camera distance instead of angle.
- Hunter eyes vs prey eyes — a related community label that also bundles eye-socket depth alongside canthal tilt and brow overhang.
- How does Omoggle's scoring work? — the publicly described mechanics this term shows up in.
