I've recently stumbled across an app called "Be My Eyes" (thank you, slightly weird Instagram feed) - which is an app to connect blind or visually impaired people with those with seeing eyes per video call, to help them with the little bits that are just extra hard to do when you can't see. Like reading the labels on a new machine. Or deciphering an address on a letter. Or... well. You can probably imagine lots of stuff like that.
The idea is to have a network of seeing volunteers, and when someone needs an eye, they can call. First volunteer who takes the call gets to see the problem (pun intended), and help solve it. A really neat idea!
