Objects in the mirror are closer than they appear. Why? Because the mirror bulges in the middle. Imagine the mirror as plastic wrap spread across a frame. If you took a ball and pressed it into the wrap it would bulge outward taking the shape of the ball. This is a convex mirror. Light reflects differently in this kind of mirror, bouncing off at an various angles. In a flat or planar mirror light reflects at ninety degree angles virtually recreating a picture of the object being reflected. In the convex mirror on the passenger side of cars the different angles of light compress the image in the middle and expand the image at the outer edges increasing the field of vision by about 30% but making reflected objects appear to shrink. Both mirrors are useful in their place. If you want to see around a corner you’re going to need the convex type, but if you are trying to put in your contact lenses a flat mirror is going to be your best bet.
Have you notice how some people have a wider perspective than others? They can see things other people don’t see. On the other hand there are people who are very good at reflecting exact pictures of what they see. Same light, different reflection. Mirrors have warnings. People don’t. In relationships it is often a good thing to suspend judgment about who saw something in a certain way until you have a better feel for their perspective. Flat mirror types often feel like the picture they see is getting distorted by convex mirror types. Convex mirror types often feel like the flat mirror types aren’t looking at the big picture. Both perspectives have value and can be combined to help you safely navigate your relationship. Either way you see things, you are closer to each other than it appears.
