      Eyes do grow! But not as much as the rest of our bodies. I’m not sure exactly, but it might be because our eyes only work at a certain size and if you make them too small, they stop working properly. If you’ve ever play around with a lens (e.g. a magnifying glass), you’ll see that the distances of your eye to the lens and the lens to the object are important. As your eye also has a lens, it could be for similar reasons. (But this is all just a guess, based on what I know about lenses!)
