An adjustably opaque window (50) including an external pane (52), an internal pane (54), a light transmission control layer (56) and a shock-absorbing layer (58) is provided. The external pane (52) and the internal pane (54) provide a cavity (60) between them, and the light transmission control layer and the shock-absorbing layer are positioned in the cavity. The shock-absorbing layer is a flexible sheet (62) that supports and protects the light transmission control layer. The light transmission layer consists of liquid crystal cells (66). The transmission ratio of the cell6; can be controlled variably.
