Switchable glasses have become increasingly popular as a modern solution for controlling window transparency. In this article, we will provide an honest review of the pros and cons of switchable glasses, helping you make an informed decision about their suitability for your needs.

What Are Switchable Glasses?

Switchable glasses, also known as smart or electrochromic glasses, are advanced glazing materials that have the ability to change their transparency or tint in response to an applied electric current. These glasses offer a convenient and efficient alternative to traditional blinds, curtains, or shades for privacy control and light management.

How Do Smart Glasses Work?

Smart glasses consist of multiple layers, including a conductive film, an electrochromic layer, and an electrolyte. When an electric current is applied, ions migrate within the glass, causing the electrochromic layer to change its opacity or colour. By controlling the current flow, the transparency of the glass can be adjusted from transparent to translucent or even completely opaque.
