Is there such a one-way mirror?

[Luis Erick Coy]

Hi everyone!

I'm wondering if there is a one-way mirror that works like the one illustrated in the image below:

I know that most one way mirrors work differently, reflecting light from the brightest side and letting light through to the dark side. Is it possible for a mirror to let light through it to the dark side and acts like a mirror to the dark side?

I did my best to explain myself, but I apologize in advance if this sounds confusing.

Have a nice day!

How do you manage the keep the inside dark if light from the outside comes in?

Maxwell's demon for light? That would violate the second law of thermodynamics.

There are mirrors which on one side look like any mirror (to a human being),
but if standing on the other side they are transparent (though dark).
I have no idea how that works. but it does exist.

I'd say the answer to your question is no, since light is reversible (in the absence of scattering).

It is just a semi-transparent mirror, and one side is lit much better than the other side.

If the light is bight enough on one side and dark enough on the other you get the same effect with ordinary glass. People on the bright side have trouble seeing in and so do birds. Had two hit our living room window yesterday.
