Well, I'm right handed but left eyed, since I caught a cricket ball with my left eye at age 18 (a long time ago believe me). At 36 I had an interocular implant which makes it possible to use my right eye, but I get internal reflections in the eye instead of the scope, so I stick to the left, which has its own share of problems (yes, that sentence is now long enough) . This could be why I now prefer imaging to visual observing.
Come to think of it, I'd give my right arm to be ambidextrous
.
Cheers
