I do believe it is a dominant eye issue. I was at Gander moutain today so I was looking at different binos. The guy handed me a pair that cost $400. I handed them back to him and told him they were blury. He looked at me like I was nuts. So he gave me a pair that cost $1000. I could finally see right. Better glass quality I guess, It did correct my problem though. I'm sure not planning on spending that kind of $$$. I guess I'll have to keep closing one eye and use the pair I have.
