Everybody had sunglasses and they're used to wearing them (even indoors) A quick quiz of the people in my office shows that: 0% were wearing sunglasses inside at the time of asking ~7% said they wear sunglasses inside on a regular basis ~25% said they do not own sunglasses I don't dispute the other points you make, but on this issue it seems you are a bit bubbled/optimistic.
