Dear Student,
Those glasses in which one side reflects light and other side allow light to pass through it is called "Tinted glass". Its one side is layered by a film which act as a reflector and reflects back the light and as a result we see our own image. But on the other side it just works as a normal glass and transmit the light through it.
