I would guess that a lot of those that are failing eye tests do have perfectly good eyesight, but that their eyesight is not being tested under the correct conditions and possibly not at the correct distance from the eye sight test chart.
That might be a factor, but I would imagine the main problem is that under the normal Group 1 standard you can get away with having a weak eye (or only one eye, as per Grandad's manor) whereas the Group 2 standard is a lot more stringent in that regard, and 'monocularity' is definitely out. Also, if you need glasses or contact lenses that's irrelevant under the Group 1 standard, but with Group 2 you also have to reach an acceptable standard
without wearing you glasses or contacts.
As far as I can make out the bad eye under Group 2 has to be the same standard as the good eye under the Group 1 standard, and the Group 2 good eye a fair bit better than the Group 1 good eye.
There's a makeshift print-out eye chart here:
