Woman reflecting on mirror

Do you ever walk into a changing room and worry that the mirror is actually transparent and that someone’s watching you on the other side? 

In a world where perverts will do pretty much anything to spy on us in situations that are supposed to be private, we have every reason to be concerned about these mirrors.

If you’re in a situation where you’re just not sure, keep reading and follow these 6 tips to spot a two-way mirror!

Check The Way The Mirror Is Installed

It’s a quick test to determine whether the mirror is transparent or not. If you notice that the mirror is hanging on the wall, check if there’s actually a wall behind it, that’s when you know you’re safe! On the other hand, if you notice that the mirror is a part of the wall itself, it could be a sign this is a two-way mirror. You can be seen by the people standing on the other side of the wall.

Pay Attention to the Lighting

The effectiveness of a two-way mirror greatly depends on lighting in the changing room. Look around and observe the strength of the lighting. If it seems very bright, it’s easier for someone on the other side to see you, and there’s a good chance you’re looking at a two-way mirror. But if the lighting in the room is more on the dim side, it’s most likely a regular mirror.

Just Use a Fingernail!

Simply put your fingernail against the mirror. If you can see a gap between the mirror and your nail, it’s most likely a normal mirror. But if it seems like your finger is directly touching its reflection in the mirror. You’re probably not paranoid to think it’s a two-way mirror.

When in Doubt, Tap It Out

This step is the simplest, just tap on the suspected mirror using your knuckle. If the sound produced is dull and flat. It’s most likely a normal mirror, since it’s installed in front of a wall. An observation mirror, however, will produce a reverberating, hollow sound, as it’s placed in front of an open space.

Lights Off!

If you’re still in doubt, turn off the lights in the room and shine a light on the mirror using your smartphone or any other tool. If it’s a two-way mirror, you’ll probably be able to see the other side since it will likely be illuminated.

The Last Resort

Consider an extreme measure, such as breaking the glass, if you have no other option. If it’s a normal mirror, it’ll likely shatter, and you’ll either see a solid wall or the mirror’s backing. However, if it’s a two-way mirror, you’ll be able to see another room behind it.

But before shattering the mirrors in every room you set foot in, you should know that this measure should only be taken when you are in danger or if you feel threatened.

Sure, mirrors aren’t the only objects that could be used to spy on you in closed rooms, so keep an eye out for small openings in the walls, as they could contain hidden cameras with fisheye lenses.

Always watch out for all the possible threats to your privacy, because nothing is as precious as your personal safety!
