A while ago I signed up as a sighted person on Be My Eyes. I didn't get as many calls as I had hoped, but I was glad to help out on the few that I could. One call was to read envelopes of incoming mail, another was to read pill bottles, and then there was the two funny guys on big cozy chairs with shopping bags of cereal boxes and wanted to know what was what. I remember one guy really didn't like one type. The app had a unique feature for the sighted person to turn on the camera of the vision impaired person.
