If you look at the first and third pictures you can see that the helmet has moved upwards in the third, thus taking the goggles with it. It's just a case of Luke's helmet being pushed up slightly when he has turned around and then he adjusts it off screen. No need for a fix here.

And R2's head panel doesn't really need fixing either. Not only it it almost impossible to fix in the 2 shots because there is so much 3d spacial movement, but he has just been thrust through the air and had a pretty bad landing so it could easily have been disjointed
