Two questions:

1. "Fovea, where light is in focus"; this must be where the digital 
chip Foveon gets its name?

2. Not exactly a lazik question, but, I'm 43 years old, and my face 
is crammed into a 21" monitor most of the time nowadays. My 
doctor says I have "Forty-itis". I've always been freaked about 
focusing; if you look into the viewfinder of a Hasselblad (or any 
camera), you are not "focusing" on the ground glass, right? You 
must be focusing on the distance of the subject. 

IOW, I can't see closeup at all. I see faraway fine. If I look through 
the viewfinder of my hassie, and I'm focusing on a subject that's 
25 feet away, are my eyes "focused" at 25 feet, or are they 
focused on the distance to the viewfinder ground glass? (I guess 
I know the answer,because I see fine through the camera, even 
without any diopters, but a good friend CANNOT focus my 
Hasselblad; claims it never "pops" into focus.)
