Blackout Drapery
Blackout curtains are fabric drapes or shades that cover your windows. They block out sunlight and artificial light from passing cars, streetlights, and other sources. These shades can provide an extra layer of protection over blinds, which tend to have gaps that allow light to leak through. With blackout curtains, you can sleep in near-total darkness any time of the day or night, even if you live in an urban area with light pollution
