Does smart glass let light in?


Smart glass, also known as switchable glass or PDLC (Polymer Dispersed Liquid Crystal) glass, has transformed the architecture and interior design industries. Many wonder whether smart glass can allow natural light into a space. In this blog, we will explore the capabilities of smart glass and shed light on its ability to transmit natural light.

Smart Glass Technology:

Smart glass operates on the principle of PDLC, where Polymer Dispersed Liquid Crystals are used to control its transparency. By applying an electric current, the glass can switch between transparent and opaque states, offering privacy and customization options.

Privacy and Transparency:

Smart glass strikes a balance between privacy and openness. It allows users to switch between transparent and opaque states, offering control over visibility and ensuring privacy when needed. This versatility provides a dynamic solution for various settings.

Preserving Natural Light:

Smart glass enables the optimization of natural light intake. By allowing daylight to pass through, it promotes well-being and productivity. Harnessing natural light has been linked to improved mood, energy levels, and overall satisfaction within a space.

Customizable Light Transmission:

Smart glass offers the flexibility to adjust light levels. By controlling the transparency of the glass, users can fine-tune their environment according to their preferences. This ability to customize light transmission enhances comfort and creates a pleasant atmosphere.

Sustainable Design:

Smart glass contributes to sustainable design practices. By maximizing natural light utilization, it reduces the reliance on artificial lighting and lowers energy consumption. The incorporation of smart glass aligns with green architecture principles, promoting energy efficiency.

Applications of Smart Glass:

Smart glass finds applications in various settings. In residential spaces, it enhances privacy without compromising natural light. Commercially, it creates engaging and dynamic environments. Its versatility makes it suitable for offices, hotels, healthcare facilities, and more.

Factors Influencing Light Transmission:

Light transmission in smart glass can be influenced by factors such as glass tinting, control settings, and external conditions. Understanding these factors helps users optimize the desired light levels and adapt to changing environments.

Advancements in Smart Glass Technology:

The technology of smart glass continues to advance. Electrochromic glass, for example, offers even more possibilities for controlling light transmission. As technology progresses, we can anticipate exciting developments and expanded applications for smart glass.


Smart glass technology enables the transmission of natural light while providing privacy and customization options. Its ability to switch between transparent and opaque states empowers users to control their environment. By optimizing natural light intake, smart glass enhances well-being and productivity. Moreover, it contributes to sustainable design practices by reducing energy consumption. As advancements unfold, smart glass holds great potential for shaping future interactions with light in the built environment.
