If someone with a glass eye is using a smartphone then one would suspect they are seeing their other, real, eye. This can then be scanned as normal.

  You'd think so, but iPhones are incredibly useful to blind people. https://finance.yahoo.com/news/david-pogue-on-iphone-voiceover-163733668.html https://finance.yahoo.com/news/david-pogue-on-iphone-voiceov...

    The first time I saw a blind person using an iPhone on the subway (years ago, I think it was an iPhone 4), I was completely blown away at how much he could do with it. Personally I think apple should allow you to turn the backlight for the screen off entirely for their use. Perfect over the shoulder privacy and better battery life to boot!

      It's called "Screen Curtain" and it's been around for a long time.
