Privacy is one of the issues that prevents people from using glass, especially when it comes to their showers and bathrooms. However, thanks to modern technology, there is a way to change a glass’ opacity levels. This technology, also referred to as ‘smart glass’ involves the use of an electronic switch that when flicked will transform these transparent walls into completely white walls that will block any light from passing through. This technology is often used in glass walls, doors, and even wide windows in order to prevent people outside from seeing the interiors of the house or commercial space. There are also other alternatives aside from using this technology. For one, homeowners can choose to have tinted glass, frosted glass, obscured glass or other similar glass pieces that have the same effect.
