Neighbors can partially see through sheer curtains, especially during the daytime when there is more natural light outside than inside. Sheer curtains are made from lightweight and translucent fabrics that allow some visibility from both sides of the window. When the light is brighter outside and dimmer inside, the effect is more pronounced, making it easier for people outside to see into the room.
However, the level of visibility through sheer curtains depends on several factors:
Lighting conditions: As mentioned, the amount of light on either side of the curtain affects visibility. During the day, with the curtains drawn but the room well-lit, people outside may see silhouettes and movements, but specific details might not be visible. At night, with lights on inside the room and darkness outside, visibility increases, making it easier for neighbors to see inside.
Distance: The proximity of neighboring buildings or the distance between your window and your neighbor's vantage point will also impact how much they can see through the sheer curtains.
Sheerness of the fabric: Not all sheer curtains are created equal. Some fabrics are more translucent than others, and the thickness or density of the fabric will affect the level of privacy.
Angle of view: The angle from which someone looks at the window can influence what they see through the sheer curtains. For example, if someone is standing perpendicular to the window, they may have a more obstructed view compared to someone directly in front of the window.
To increase privacy, you can consider using additional window treatments alongside the sheer curtains, such as blinds, shades, or thicker curtains. These options allow you to control the level of visibility and natural light while still maintaining a stylish and functional window covering.
