I have tinnitus, and bought a Bluetooth audio sleep mask so that I could sleep with the TV off and not keep my partner awake. That in itself was a game changer, but on top of that, I sleep way better with my eyes covered and I use it now even when I’m not listening.

(It’s extra weird because I have thick eyelids and see black when I close my eyes even in a well lit room, so I never considered that I’d need one.)
