ELI5: Why do sharks, being predators, have eyes on their sides?

Most predator species like lions, bears, falcons, and even humans have their eyes on the front of their faces to help with hunting, while prey species like cows, rabbits, or chickens have their eyes on the sides. Why do sharks, a predatory species, not have eyes aimed forwards?

They eyes front for predators rule only seems to apply to land creatures. On land, the things that you need to see are usually near the ground. You don't need to be able to see what is directly above or below you. Fish do. Having eyes on the side of your head lets you see above and below much better than having your eyes on the front. Which is why almost all swimming aquatic animals have their eyes on the side of their heads.
