Can you become a commercial airline pilot in Europe while being monocular I’m not sure if I could get a EASA medical class 1 while being monocular. But I think that you can get a soda in the us and I want to know, if I could take a FAA medical class 1 and then fly in Europe with a FAA. Or even better if I could get a soda in Europe and get a EASA medical class 1, and become a commercial airline pilot in Europe while being monocular.

I know this has been asked before but that only covers about getting the license, and I want to know if I could get a soda.
Pilot certificates don't give you permission to fly in a location, they give you permission to fly an airplane registered by that authority anywhere in the world. In other words, if you have an FAA pilot certificate you can fly a US registered airplane no matter where it is. If you have an FAA ATPL and appropriate class of medical you can work for any airline that flies US registered airplanes. The same is true for any licensing authority. 

The reverse is not true, you could not get a FAA certificate and fly a UK registered airplane, for example, even if it was in the US. There are some cases where you can get a local certificate on the basis of another equivalent certificate, but I believe you always need to be able to pass the local medical.
