ELI5: Are our eyes and cameras similar in the way they focus and unfocus on things?

Not really. Out eyes have squishy jello lens, so they focus by physically stretching the lens to make them thinner or thicker, while cameras have two sets of (glass, hence unstretchable) lens that are put closer of further apart to change the focal distance.
