Glasses glare and 'eyes closed' false positives

Applicants with glasses meet a special kind of rejection: a portal insisting their eyes seem to be closed, or that they are not looking at the camera, when they were staring straight into the lens. These are false positives from automated eye detection, and glasses are the usual trigger, because glare, tint and frame edges hide exactly the pixels the detector needs. This guide explains the mechanism, the rules behind it, and the three reliable ways out. The country-by-country rules live in the glasses and head coverings guide.

Why software says your open eyes are closed

Eye detectors look for the iris and the eyelid boundary. A reflection across the lens, a tinted or photochromic lens that has darkened, or a thick frame crossing the eye all remove that evidence, and the detector reports what it cannot see as closed or looking away. HM Passport Office's upload produces exactly this: users report 'my eyes seem to be closed even though they are wide open' on the UK digital photo, and our help entry documents the message. The underlying rule is real, though: gov.uk requires that the eyes are not covered by frames or any glare, reflection or shadow, so the detector is enforcing a published rule badly rather than inventing one.

The rules that make glasses hard

Where glasses are allowed, they are allowed conditionally. Canada permits them on the Canadian passport photo but refuses sunglasses and tinted lenses, including prescription ones, even when the eyes are clearly visible, which catches photochromic lenses that darkened in daylight. The Netherlands requires fully visible eyes through clear lenses with no reflection and no shadow for the Dutch passport, and tells applicants to take the glasses off if a reflection cannot be avoided. The United States simply bans glasses in the passport photo altogether, which at least cannot false-positive.

Three ways out

In order of reliability.

1.Take the glasses off. No authority in our dataset penalises a photo without glasses, and every eye-detection problem disappears with them.
2.Kill the reflection at the source: light from two sides rather than one lamp behind the camera, flash off, chin down a few millimetres, frames nudged down the nose so the lenses angle away from the light. Then check the photo at full zoom: both irises fully visible, no bright streak on either lens.
3.If a portal still objects to a photo whose eyes are plainly visible, continue where the portal allows it; HMPO's automated check is advisory and its staff make the final decision.

How our checker behaves

We measure eye openness and gaze from face landmarks, and we publish the uncertainty instead of hiding it: a result in the grey zone is shown as 'Check', a warning, rather than a hard fail, precisely because narrow eyes, lens reflections and strong frames push these measurements around. Whether you are wearing glasses is a question we ask you before payment rather than guess (the high-quality render after payment also checks for glasses), since tint and glare on a lens are judgements a camera makes badly. That honesty cuts both ways: a pass from us on the eye rules is a measurement, not a promise that a portal's stricter detector will agree, which is why the re-shoot advice above is worth following even after a clean checklist.

Frequently asked questions

My eyes are naturally narrow and checkers keep failing me. What should I do?

Shoot in bright, even light with the camera at eye height, which maximises the visible iris. A borderline result from our checker shows as 'Check', a warning, rather than a fail. Portals staffed by humans, like HMPO, accept photos their automated check queried.
