An acrylic two way mirror, also known as one way mirror, is a semi-transparent mirror which provides privacy and allows discreet viewing from the darker side. An acrylic two way mirror relies on the lighting conditions to conceal the mirror side. Due to its high strength, acrylic is ideal for clinical observation, where a glass mirror would potentially be shattered. In addition to privacy and observation, acrylic two way mirrors are also used for hiding smart mirrors and optical illusions, infinite mirrors etc.
