Hi maestro,
Welcome to neurotalk! the double vision is coming from the back of your head in the optical lobe where a persons eyesight is. I've had 2 brain surgeries done and it took awhile to recover. My best advice to you is to see an Epileptologist which is a Dr that specializes in epilepsy but they know much more than a neurologist and how the brain works. I wish you the best of luck and May God Bless You!
