A multi-layered element with variable optical properties is related to optical engineering and is intended for the manufacture of translucent structures. The result is a simplified design. The element contains a first sheet (1) and a second sheet (2) which are superimposed on one another, the space between said sheets being hermetically-sealed. The sheets are made of an optically-transmitting material. According to a first variant, one of the adjoining surfaces is elastic, and the same surface or the surface adjoining same is diffractive. According to a second variant, one of the adjoining surfaces is soft, and the other is diffractive.
