Buying Binoculars

Hi all, I'm looking to buy a pair of binoculars soon, and I've been researching the different aspects I should look for in an astronomy book of mine. I know where I stand with regards to apperture, magnification, coatings and cost etc., but the book mentioned entry and exit pupils, and I was wondering how important this is in choosing the correct binoculars?

As my eyes are likely to change alot while I use the binoculars for astronomy (I'm 15 now and apparantly pupil dilation changes alot with age), is it worth being picky about the entry/exit pupil sizes with regards to the binoculars I buy?

Cheers
Albino
