My lenses were made when I was shooting weddings as my eyes would get very
tired after shooting all day. I seldom use them any more. I suspect most
people would be fine if they corrected for the magnification and ignored the
astigmatism for their camera eyepieces. Sometimes it helps to not know which
way is up.....but for a fighter pilot????? /jmac

I have slight astigmatism in my viewfinder eye. Nonetheless, rotating
the camera seems to have little effect on the resolution of focus in
that eye. So I have one lens per eyecup ... and I don't know which way
up it is anyway ;-)
