Eyes!
On the same topic, not wanting to start another thread...
When you go to have your medical, do you actually have to have your eyesight corrected to basically 20/20? I'm slightly short-sighted in one eye (~19/20), but have 20/20 with the other and 20/20 when combined. I did have a prescription for the small amount of correction required, but never got glasses since it didn't seem worth it. Would I need to get this prescription made up for the medical?
