AARP Eye Center
In the senior community where my mother lived for years and years, they had a system where each of the residents placed a colored tag outside their door by a certain time each morning and each evening - the tags and colors were different for morning and evening.
This was a high-rise, so one of the floor residents would do the checking - and report any oddities to the security staff for further checking.
The system worked well yet it was not intrusive and there was some very old ladies living there - well over 90.
