Why Glasses Are Banned in Passport Photos – ICAO 2026 Rule Explained

The International Civil Aviation Organization (ICAO) publishes Doc 9303 — the global standard that defines how machine-readable travel documents, including biometric e-passports, must be structured. The standard covers everything from chip encoding to photo specifications. In its 2015 revision, ICAO strengthened the recommendation against glasses to protect the accuracy of automated biometric facial recognition at border control.

ICAO's guidance is technical in nature: glasses cause two distinct problems for facial recognition algorithms. First, frame occlusion — the physical rims of glasses cover portions of the eye area, which is among the most important regions for biometric matching. Second, lens glare and reflection — even anti-reflective coatings can produce specular highlights under the lighting conditions typical of passport cameras, partially obscuring the iris and eyelid contour.

Since most countries adopted the ICAO Doc 9303 standard for their own passport programmes, the recommendation quickly became mandatory legislation or administrative guidance in country after country.

Modern biometric facial recognition systems rely heavily on the periocular region — the area around and including the eyes. When glasses are present:

• Glare from lens surfaces creates bright spots that the algorithm cannot distinguish from features of the face, distorting the eye region in the biometric template stored on the passport chip.
• Frame shadows cast dark areas across the upper or lower eyelid depending on lighting direction, altering the apparent shape of the eye.
• Frame occlusion physically hides a strip of the face above and below each eye, reducing the number of usable landmarks for matching.

These problems cannot be reliably corrected in post-processing — which is why the solution adopted by every major authority has been to prohibit glasses entirely rather than attempt case-by-case assessment.

Transparent (clear) contact lenses are permitted in passport photos in all major countries. They are invisible in the photo and do not affect biometric matching.

Coloured, tinted, or cosmetic contact lenses that visibly change your natural eye colour are not permitted. This includes subtle enhancement tints. If your eyes appear a different colour in your passport photo compared to in person, the application may be rejected. Photochromic (transition) lenses must be photographed in their fully transparent state — any visible tint is grounds for rejection.

Sunglasses — including prescription sunglasses and lightly tinted fashion frames — are prohibited in passport photos without exception. This rule applies regardless of whether the lenses are dark or only slightly tinted. The eyes must be fully visible without any coloured lens in front of them.

In very rare circumstances — for example, after certain types of eye surgery, or in cases of severe medically documented photosensitivity — a person may have a genuine clinical need to keep eyewear in place. What you need to know:

• Medical exemptions are not a standard procedure at most passport authorities. There is no guaranteed pathway in most countries.
• If you believe you qualify, contact your national passport authority before your application. Do not simply submit a photo with glasses and expect acceptance.
• A signed letter from a licensed physician explaining the medical necessity is typically required alongside the exemption request.
• Even with medical documentation, some authorities may still require removal of glasses and instead note the condition on the application file.
