If blackout curtains make your room pitch black does it mean no UV is coming in?
I know UV is different than visible light, so I’m asking because I got blackout curtains from Amazon and there’s zero light in my room at all now. It’s pitch black, which I assume means no visible light, but can UV still penetrate the curtains? Specifically UVA. Just concerned for my skin is all
But I just don’t know how reliable Amazon is because I don’t know if what I bought has certified anti UV protection but it does a perfect job of making the room pitch black though
