So I can look at an object directly but i can also focus on the corner of my vision.How does it work?

It can’t. That’s fundamentally not how the eye works. What you’re doing is just paying more attention to what’s going on in your peripheral vision.
Your brain receives a lot of data every second and discards most of them, this is mostly unconscious and instinctive (we had a post about your brain instantly recognizing your name even in noisy rooms a few hours ago), however, you can make an effort to process infos you’d normally ignore. It’s more evident with other senses, for example you could feel your heart beating if you focus, even in less sensitive areas of your body (not only hands, face etc)
Because your brain can process all the visual information given to it. Peripheral vision is just harder to consciously process as its mostly processed emotionally. So sudden movement, or recognizable shapes are recognized faster than they would if you were actively focusing on them. However that doesn’t mean you cant try really hard and focus your perception onto your peripheral vision without actually moving your eyes.
