[Star Wars] What's the mechanism that Jedis use to block laser shots?

In the shows, the Jedis are usually holding the lightsaber mostly upright and waving it left and right. Some fancy twirls thrown in. This makes me think that they can see faster than normal, figure out trajectory and move the lightsaber to block it. Similar to the Matrix agents.

But then in Rogue One, Donnie Yen is dodging them even though he's blind. So are they actually using the force to change the laser trajectory? We've seen Kylo Ren catch one in midair. 

Any concrete in-Canon explanations?

The Jedi can feel where the blaster bolts will go, because the force tells them. Sort of like instinct but more powerful. 

Chirrut isn’t technically force sensitive like a Jedi but he can feel it through focus so he does have some limited sense of it.
