Smart glass is the name given to a class of materials and devices that can be switched between a transparent state and a state which is opaque, translucent, reflective, or retro-reflective. The switching is done by applying a voltage to the material, or by performing some simple mechanical operation. Windows, skylights, etc., that are made of smart glass can be used to adjust indoor lighting, compensating for changes of the brightness of the light outdoors and of the required brightness indoors.

Famous quotes containing the words smart and/or glass:
“Often, we expect too much [from a nanny]. We want someone like ourselves—bright, witty, responsible, loving, imaginative, patient, well-mannered, and cheerful. Also, we want her to be smart, but not so smart that she’s going to get bored in two months and leave us to go to medical school.”
—Louise Lague (20th century)
“It is difficult to read. The page is dark.
Yet he knows what it is that he expects.
The page is blank or a frame without a glass
Or a glass that is empty when he looks.”
—Wallace Stevens (1879–1955)
