When we look in a mirror, we see a reflection of ourselves. This common experience often leads to a curious question: do other people see us as we see ourselves in a mirror, or is there a difference in how we are perceived? The way we view our own image versus how others view us involves both the physics of light and the intricate workings of human perception.
Understanding Mirror Images
Mirrors create an image through specular reflection. When light rays strike a smooth, polished surface, they bounce off at the same angle they hit it. This reflection causes an apparent reversal of the image. A standard flat mirror performs a horizontal inversion, flipping the image from left to right. This left-right reversal is why if you raise your right hand, your reflection appears to raise its left hand. Despite this horizontal flip, mirrors do not invert images vertically; your head remains at the top and your feet at the bottom. This optical phenomenon is purely a result of how light interacts with the reflective surface. The image you see is a virtual image, appearing to be behind the mirror.
How Others Truly See You
The way others see you is fundamentally different from your mirror reflection. When someone looks at you, they are seeing light directly reflected from your body, not from a mirror. This direct perception means there is no horizontal inversion. They perceive you in your true orientation, without any left-to-right swap. A photograph of yourself represents how others typically see you. A camera captures light directly from an object, much like the human eye, without introducing the specific horizontal reversal that a mirror does. Therefore, the face and body orientation in a photograph is a more accurate representation of how you appear to the world around you.
The Brain’s Role in Visual Perception
Our visual system also performs a type of “inversion,” though it is distinct from what happens in a mirror. When light enters the eye, it passes through the lens and is projected onto the retina, a light-sensitive layer at the back of the eye. Due to the optics of the eye’s lens, the image projected onto the retina is actually upside down and reversed left-to-right. This is a purely physical consequence of how light rays converge and cross within the eye. Despite this initial inverted projection, we perceive the world right-side up and correctly oriented. This remarkable feat is accomplished by the brain. The visual cortex processes the inverted retinal image. It interprets and reorients this information, effectively “flipping” the image back to its correct vertical and horizontal alignment. This neural processing allows us to experience a coherent and accurate view of our surroundings.
Why Your Mirror Image Looks Different
The reason your mirror image might feel more familiar to you than a photograph is rooted in constant exposure. You spend countless hours looking at your reflection in mirrors throughout your life. This consistent interaction means you become deeply accustomed to seeing your face with its horizontal inversion. The subtle asymmetries that exist on everyone’s face are presented in a specific, reversed way in the mirror. When you then see a photograph of yourself, which shows your un-inverted appearance, these asymmetries are presented in their true orientation. This can make the photographic image feel unfamiliar or even slightly “wrong” because it deviates from the version of yourself you are most used to seeing. Your brain has formed a strong internal representation based on your mirror reflection, making the true external view feel less recognizable.
