I use a Redfield 10x42. They are owned by Leupold now and I can look behind that glass all day without getting eye strain. I would eventually like to get a Swarovski or Zeiss, but for now they work. maybe next Christmas.
I do have a pair of Leupold 8x25 (Rogue) and while they are GREAT for hunting in the woods, for open areas I would go with my Redfield.
For my eyes, prism binos are the way to go.
Some binos with good coatings can be just as good as HD binos. Best to look through them at a store and if you can look outside, all the better.
If you have to adjust the Diopter Adjustment too much at various distances, shy away from those...as they will just give you headaches (eye strain) later if you have to look through them too much.
If you can get good binos on a decent bipod/tripod/mount, you would be amazed at how much more detail you can view versus just trying to holding them steady.
