First Class Medical
As long as you are in good general health, you can get a First. Really, the physical is complete but not as thorough as your own your M.D. or D.O. would give you.
If you wear glasses or contacts, you can still get a First, but you might have to take a vision-correction restriction, just the same as for your driver's license.
As long as you maintain good general health, you can maintain First Class Medical Certification.
