I have curtains. They make me see nothing and I don’t have to wear them.

I’m glad that works for you!

In my house we have roller shutters and they make you see nothing.
I’ve been at places without proper shutters… tried sleep masks… and they don’t fully block light nor do they stay in place after even a single turn in bed. I ended up wrapping one of my black stockings around my head like a blind fold to actually sleep. >.<’
