From Minnesota Department of Natural Resources:
"An owl's big eyes let in a lot of light so it can see better in the dark than we can.
Most birds have eyes on the sides of their head, but an owl's eyes point straight ahead like ours to help it judge distance."
From Carolina Biological Supply:
"owls can turn their heads around far enough to see directly behind them. The total range of head rotation for most owl species is an amazing 270 degrees."
They also have more information about the make-up of the owl eyes at that site, as well.

The number of light receptive cells and the shape of their fovea are factors. They also have a reflective mebrane behind their retina known as a tapedum lucidum which helps them see in dimmer light.

The huge size of their eyes, which provide greater light-gathering ability, just like a larger lens on a telescope.

Their big eyes. The reason they need to be able to move their heads all the way around is that their eyes are too big to shift in their sockets, so it's kind of secondary.

Their eyes are facing forward instead of sideways giving them the binocular vision that we enjoy. They have better light sensitivity for night vision.

The density of the cones and rods and the size of their eyes.

they can move their head 360 degrees, allowing them to see all around without moving their body
