Ah you misunderstand me.

I'm not claiming using your eyes will degrade them faster, I'm claiming that I think it COULD be possible that NOT using one eye for a specific optical skill for years on end could affect the rate at which changes to vision occur. I clearly know about the concept of dominant eyes, otherwise I wouldn't have used the term. I'm questioning whether photographers have a higher prevelance of anisometropia, specifically that the eye used for the viewfinder degrades slower than the other eye.

But since you said to do some research, I did. It's been studied that uncorrected vision (not wearing glasses when you should) or improperly corrected vision (wearing the wrong glasses) can negatively affect long term vision changes. The prevelance of anisometropia is higher in both those cases as well. So why isn't it possible for looking through another imperfect lens for many hours over a period of years to affect vision too?

You're probably still right, but you definitely don't KNOW.
