Sheer curtains add a soft, airy touch to any room and can provide some daytime privacy by diffusing light and blurring the view from outside. However, because they are see-through, they don’t offer much privacy at night when indoor lights are on. To enjoy both natural light and privacy, it’s best to layer sheer curtains with heavier drapes or blinds. Choosing denser weaves or adding frosted window films can also improve privacy. Overall, sheer curtains work well when combined with other window treatments for a perfect balance of style and privacy.
