What is the glass mirror that can only be seen from the inside out? 

Which glass mirror that can only be seen from the inside out? One-way see-through glass (single-sided mirror) can achieve this effect. Of course, this effect is only available during the day, and when it is turned on at night, this glass is no different from ordinary glass.

One-way perspective glass principle: This kind of glass has a high reflectance to visible light. During the day, the outdoor is brighter than the indoor. The one-way see-through glass is similar to the ordinary mirror. The outdoor scene can not be seen indoors, but the outdoor scene can be seen indoors. When the lights are turned on at night, the outdoor is darker than the indoors, and the indoor scenery can be seen outdoors, and the outdoor scenery can be seen indoors.

Field of use: One-way see-through glass is mainly used for concealed observation windows, holes, etc. It is widely used in public inspection law institutions, mental hospitals, university research institutions, large conference rooms, high-end offices, monitoring rooms, etc. With the cooperation, you can not see the inside, and you can see the effect inside.
