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:
“Baby, they were plenty smart when they made you beautiful.”
—James Gleason (1886–1959)
“They are, as it were, train-bearers in the pageant of life, and hold a glass up to humanity, frailer than itself. We see ourselves at second-hand in them: they show us all that we are, all that we wish to be, and all that we dread to be.... What brings the resemblance nearer is, that, as they imitate us, we, in our turn, imitate them.... There is no class of society whom so many persons regard with affection as actors.”
—William Hazlitt (1778–1830)
