If your asking how they work, they work because they have many tiny pieces of metal integrated in the glass that reflect light and also on one side of the window, the environment is darker. You can experiment with this by waiting until night time and turning on your room light and looking out of the window. It’s will be difficult for you to see outside, but very easy for people to see inside
