I've had bifocals since my 20's as well...not much fun. I remember it took me quite awhile to get used to them...but you will. The longest adjustment came with walking down stairs...even a single step could give me vertigo if I looked down the wrong way as I stepped off. LOL But even that became second-nature after awhile.

They do make "bifocal" contacts, but they only work for certain people under certain conditions. They're not for everyone.
