I'm Ernie. I can still see 1% in a very small field of view (0.05 degrees), so I'm always careful not to bump into anything. By comparison, people with a normal field of vision can see about 140 degrees horizontally and 80 degrees vertically.
I haven't always been so visually impaired. 'My brain keeps filling in spaces based on what I've been able to see before. My brain is working overtime and that makes me want to limit the signals I receive, because otherwise I get overtired. So that's why I dose the signals I receive through equipment and keep it on a certain basis'. So technology is very important to me as a basis. I currently mainly use the iPhone for reading a book and playing music. I also use my iPhone to operate the lighting, the heating thermostat and the blinds. In addition, I use Google Home, so that I can do everything spoken.
