Zebra roller blind , also known as a dual roller blind or day and night blind, is a type of window covering that consists of two layers of fabric. The fabric is made up of alternating translucent and opaque stripes, usually in a horizontal pattern, that can be adjusted to control the amount of light and privacy desired. When the stripes align, the blind provides privacy while still allowing some natural light to enter the room. When the stripes overlap, the blind blocks out the light completely.

Zebra roller blinds are popular due to their modern and versatile design. They can be adjusted to various positions, allowing for different levels of light filtering and privacy. Additionally, they are available in a wide range of colors and patterns, making them suitable for various interior decor styles.
