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:
“For he purrs in thankfulness, when God tell him he’s a good Cat.
For he is an instrument for the children to learn benevolence upon.”
—Christopher Smart (1722–1771)
“More Safe, and much more modest ‘tis, to say
God wou’d not leave Mankind without a way:
And that the Scriptures, though not every where
Free from Corruption, or intire, or clear,
Are uncorrupt, sufficient, clear, intire,
In all things which our needfull Faith require.
If others in the same Glass better see
‘Tis for Themselves they look, but not for me:
For MY Salvation must its Doom receive
Not from what OTHERS, but what I believe.”
—John Dryden (1631–1700)
