I think the US at least does sight tests periodically? The UK still doesn't do that, you're required to have decent vision to drive, but the license renewals are just paperwork, pay the money and click a web form.

There is talk in the UK of requiring sight tests for the elderly. Historically UK licenses required frequent renewal, when they were centralised for convenience they ceased to have a renewal step, and it was kinda-sorta reintroduced much later once they had photographs because of course a 40 year photo is unrecognisable. But because of the focus on photographs the renewal step is integrated to passports, and is a chain-of-likeness documentation process. If I look a big greyer than last time in the photo I upload, pay, wait a few days, OK, some mix of humans and machines says that's the same guy as the other photo except older, replace image, print new ID.

Since it's aligned with passports (which also care about image similarity) there's no room in that step for like "Do your eyes still work?" let alone "Do you know what this fucking sign means?" or anything resembling mandatory continuing education.
