Convergence micropsia

Convergence micropsia is when things that are far away look smaller than they really are when you look at them up close.

Let's imagine you're playing with some toy cars. If you hold one car far away from your face and then bring it up close, it should look the same size the whole time. But if you have convergence micropsia, when you bring the car up close, it will look smaller than it really is.

This happens because your eyes have to work harder to focus on things up close, and when they do that, the muscles in your eyes that control convergence (the inward turning of your eyes) are also working harder. This added work can cause a bit of confusion in your brain about the exact size and distance of the object you're looking at, resulting in the object appearing smaller than it really is.

This can be a temporary condition that goes away on its own, or it can be a symptom of a larger underlying issue. If you or someone you know is experiencing convergence micropsia, it's important to talk to a doctor or optometrist to rule out any potential vision problems.
