Help! My cat keeps jumping on my head!?

This might sound funny, but it really really isn't. He sneaks up behind me while I'm sitting usually but sometimes when I'm standing. Once, he scratched my ear and it bled lots and a scar is still there. I always have scratches across my face. My mum always shuts him in the bathroom (because he has a very short memory so he forgets about what he did) but he never forgets it completely. My mum is always telling me that he's going to scratch my eyeballs someday and I'll be blind, and that scars me. But he just won't stop. She took him to the vet and the vet said that kittens jump on senior cats' heads to annoy them, but obviously I'm not a cat so I'm confused. I want him to stop! What do I do? He is a year and a half and he's a Bengal, if that helps.
