Wow blast from the past! My elementary and middle school (LAUSD in the 80s and early 90s) had this on upper windows of the classrooms that we would open with a long pole with a hook on it. Both schools were older buildings and this was already there when I was a kid. Perhaps it was an effort to soften light from a particular constant direction since these did not have interior window coverings.
