Not sure what a solution is that deals with that AND helps us sleep better etc. Every French home and apartment I've ever been inside (mostly in the Northwest) has been built or retrofitted with shutters that block out almost all outside light. They're installed on all the main windows including on living room and kitchen windows. It's just part of the nightly routine to walk around and close them. (Or, in the case of newer electric shutters, just to hit the main button to close them all.)
