Are there international airlines that allow cabin crew to have variations in vision (exc/ept color blindness)?

Question

for example, if the person has a vision of 250, or other than 20/20

Answer 1

Are you asking about cabin crew or cockpit crew? Cockpit crew must have a class 1 medical for airline flying. This requires a corrected vision of 20/30 (I believe, maybe its 20/20). There are some small vision issues that you'd never notice in normal life that can also disqualify you.

I'm not aware that our cabin crew require any type of medical certification testing other than basic employment testing. I'd have to ask them what they do. I would be surprised if there was much.

Answer 2

cabin crew do not have any vision requirements

except for severe colorblindness

They will give you a vision test and you may need to get glasses(spectacles) but thats it

Answer 3

wouldn't think so
