What test is required for an Optometrist to practice in Florida?

I know that to be an Optometrist, he/she must pass the Boards exam however Florida has its own exam. What are differences if any between these two tests?

You just need to pass the Florida Board of Optometry Exam. Go here and read about it. It should not be too much different from any other exam. You should be able to see sample exam questions from all of these exams and you can compare them yourself.
