Vierordt's law

Vierordt's law explains how we see things. It is named after a scientist called Karl Vierordt who did a lot of research about this. Basically, Vierordt's law explains how our eyes work. Our eyes are usually good at seeing things that don’t move very quickly. It means that if something moves slowly enough, our eyes will see it. But if something moves too quickly, our eyes won't be able to see it as clearly. Vierordt’s law helps us understand why this is.
