I would like to develop a glass that is reactive to current/voltage in order to create shades on them( Like the UV light on photo chromatic lenses )
If we are using photo chromatic lenses ( silver chloride and silver halide ) it darken in the presence of UV light, and the amount of darkness is fixed. And IS THERE any component that can be used to control the % of darkness by a voltage.
If there is one it can be developed to a glass that can be controlled by applications. :)
