Mirror question

[GeoCam]

I really need to get some mirrors for my bikes and could use some suggestions. I have read a few threads about mirrors and it seems that an awful lot of people use the little mirrors that attach to your bike helmet or sunglasses. I have an unusual birth defect that prevents me from moving my left eye outward. Normally, I just compensate by turning my head instead of my eyes. That doesn't work with the helmet mirror, because if I turn my head, the mirror goes with!!

So for those of you who do not/cannot use the small "third eye" type of mirrors, what have you found that you like? I have one bike with drop bars and one with mountain bike style bars.
