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:
“Glorious the northern lights astream;
Glorious the song, when God’s the theme
Glorious the thunder’s roar:
Glorious hosanna from the den;
Glorious the catholic amen;
Glorious the martyr’s gore:
Glorious—more glorious is the crown
Of him that brought salvation down
By meekness, called thy Son;
Thou that stupendous truth believed,
And now the matchless deed’s achieved,
Determined, Dared, and Done.”
—Christopher Smart (1722–1771)
“Sunshine of late afternoon—
On the glass tray
a glass pitcher, the tumbler
turned down, by which
a key is lying—And the
immaculate white bed”
—William Carlos Williams (1883–1963)
