There’s no real difference. They have a slightly different view of the world which feeds back to your brain (via the optic nerve) – this allows you to judge distances for example. Try an experiment of your own – get a friend to throw a ball at you from say 5m away then try the same when you have one eye shut. Any difference?
Some people how have problems with their eyesight often find their eyesight is much worse in one than the other, so if you look at someones glasses (with their permission) you may see the lenses are different thicknesses.

Most people find that their vision is better in one eye than the other one. When this difference is really big they can sometimes develop a squint (or a lazy eye), and it makes it difficult for them to judge close distances and they cant see 3D films at the cinema properly. Did you know that carnivores tend to have two eyes on the front of their face, whilst herbivores tend to have two eyes on the side of their face (so they can spot the carnivores creeping up on them). If you don’t know what an animal eats have a look at the position of its eyes – it will give you a big clue.

Super question. Both of your eyes are identical. The do the same job as each other, they like to the brain by long thick nerves but report to opposite sides from which they sit ( left eye to the right side of the brain andnvice versa) and they do it upside down, its your brain that works it out and tells you what’s going on visually. If for example the part of your brain on the left side that deals with 2 dimentional images is damaged and you try and draw a symmetrical object, you will only draw half of it, the right half. It’s not your eyes it’s how your brain has interpreted what you have done.
