Pixels on iPod Touch - Help

Hey,

How big are the pixies on the iPod Touch screen?

I'm currently sitting in the dark and when I'm on the home screen there are the tiniest little dot which aren't black. I can't notice them when the iPod is away from my face but when up close and looking extremely closley there seems to be a lot. I don't know if its my eyes planing tricks on me or not.

I haven't noticed them before. Is there anyway to fix or check to see if it us a pixel problem.

THANKS.
