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.<ref>{{cite journal|last1=Baetens |first1=R. |last2=Jelle |first2=B. P. |last3=Gustavsen |first3=A. |title=Properties, requirements and possibilities of smart windows for dynamic daylight and solar energy control in buildings: A state-of-the-art review |journal=Solar Energy Materials and Solar Cells|date=2010|volume=94|issue=2|pages=87–105|doi=10.1016/j.solmat.2009.08.021|bibcode=2010SEMSC..94...87B |hdl=11250/2473860 |hdl-access=free }}</ref> 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.<ref>{{cite journal|last1=Lee|first1=E.S.|last2=Tavil|first2=A. |title=Energy and visual comfort performance of electrochromic windows with overhangs |journal=Building and Environment|date=2007|volume=42|issue=6|pages=2439–2449|doi=10.1016/j.buildenv.2006.04.016|bibcode=2007BuEnv..42.2439L }}</ref>
