While shades are a common accessory for windows, a new tint has been developed that dynamically adapts to brightness, color temperature, and opacity could take their place.

Scientists from the University of Cincinnati partnered with industry professionals to develop a product that allows windows to be made milky for privacy yet allow 90% or more of available light into the room. The customizable aspect of the tint also enables users to toggle room brightness by dimming entering light and adjust the color temperature that fits the use of the room best.

Additionally, the scientists note that tuning for privacy and improved color quality isn’t the only possible use for the new technology. The windows could also be set to control infrared heat transmission, allowing building professionals to cut cooling costs in the summer and rely less on heating systems in the winter. The researchers are also quick to point out that the new tint is cheap to manufacture and can be applied to both new windows during manufacturing and retrofitted onto windows that are currently in use.
