Hair growing hack
Ok how do I translate these numbers to distance from mirror?
Camera focal length
It's not distance to mirror, it's the focal length. The focal length of our eyes is static
The "focal length" of our eyes is a subjective number, because our retinas aren't flat and our attention doesn't cover our whole field of view at the same time.
Also you only ever see your face unmirrored in photos, even your phone's front camera will mirror the picture to not unsettle you.
