On: The open-plan office is a terrible, horrible, no good, very bad idea

[RandallBrown]

I don't have any links, but most office buildings I've encountered let you turn off sections of lights. For more granular control we've simply removed the lightbulbs. (Sometimes to the chagrin of the facilities people)

If lights from far away are a problem I don't have a very good solution beyond hanging a flag or something from the ceiling to try and block the light.

Removing individual lightbulbs or hanging flags as light barriers ... I hope you are seeing that your original suggestion is deeply unrealistic.
