I have 3-5mm for smallest pupil size in my notes.

With a pupil size that small, you'd probably see a blur due to the diffraction around the pupil edge. Large amoeba are about .5mm big. 3mm sounds right.

.5mm is off by a factor of 10: http://en.wikipedia.org/wiki/Pupil

Alright thank you for the quick responses. Another question I happen to have is what number of rod cells and cone cells are normal? I received a variety of answers from the internet, and i lack a textbook.
*EDIT: I forgot to also ask about the blind spot of an eye, what would the field of view size of it be?

Okay, we are not, and I repeat NOT your source for all little miniscule Optics things.
And in reply to your questions:
Rod cells:120 million
Cone cells: 7 million
Blind spot size: 1.0-1.2 mm
That's all I have.

States was great! Our laser shoot was off by only 4mm (a personal best) and we got 2nd place!!! :D

Heyy guys...
I have been wondering, I have learned all the physical and geometric parts of optics, but now on the NY state Optics test questions about real life parameters of binoculars came up like 7x50 (I know now what it is). What else should I expect?
Thanks in advance.
Yay were going to Nats!!!
