A member asked:

Are pterygia common among airline pilots and people living in tropical countries?

No and yes: I know of no study showing airline pilots having an increased incidence of pterygia. They are more common in people from equatorial countries as well as those living in desert and harsh climates.

Pterygium: Pterygium formation is related to ultraviolet light exposure so they are much more common close to the equator (tropical areas) and in patients whose occupation yields significant uv exposure. I am unaware of a link between pilot and pterygia though.
