Also, I needed to wear glasses to avoid blackouts. I wasn't impressed and returned both pairs.

On the issue of the false pupils only:

I understand that false pupils are outside the cone of light that is delivered to the exit pupil and into ones pupils.

My large Zeiss Victory 7x42 T* FL uses AK prisms and it has large ovoid false pupils. My little Swarovski 8x25 CL Compact also shows small false pupils.

I can't see the false pupils while using the binoculars and and they have no effect on the view.
