  1. There are a number of ways to achieve such things, ranging from Very careful placement and practice ahead of time to simply having an ear piece and someone telling them where things are, etc. Some of the things presented in the video are Very easy to explain (How can you tell someone wearing big dark glasses is looking 'right at' something? You can't. And, importantly, and the reason actually blind people tend to wear them, you can't tell that they're Not), others rather less so if you assume full blindness.

  2. It generally means 'effectively might as well be blind for any task where the ability to see at least X well is significant enough that we care about it', to my understanding.
