Somewhat related, I've always wondered why outdoor solid shutters or blinds are a given in some countries/regions but nowhere to be seen in others, even though some residential areas are extremely polluted by artificial light at night.

Those were historically used to prevent damage to window panes, not block light. They are popular in areas that were settled when glass was very fragile/expensive and receive strong winds. Pre-glass, they were used to keep weather from blowing through the house.
