You can see them anywhere but it is the easiest when looking against the blue or white (clouds) in the sky.
A lot of people get confused about these. I don't claim to know absolutely what they are, but I think it's pretty obvious that they're a phenomenon of the physical human eyeball. (It's an imperfect apparatus, you know!) You're seeing the blood flowing through the minute capillaries on the back inner surface of your eyeballs. That's the dippy, dancing tiny dots with tiny tails.
The bigger circles and tube like structures are a different thing. Those are bits of junk material (mostly dead cells that have peeled off the inner wall of your eyeballs) floating around in the vitreous humor, which is the clear gel that fills your eyeballs and keeps em nice and round.
See http://en.wikipedia.org/wiki/Floaters
Both of those phenomena are completely unrelated to actually perceiving energy fields or whatnot with the eyes.
Edit: Hah, just read the rest of this thread. Was a bit hasty on posting... Ali, I've heard it described as blood like I try to rediscribe here, but I've never heard of it as the neurons firing. The article you linked on "Blue field entoptic phenomenon" explains it in much better detail. Thank you!

Also, to Focus123, I don't mean to say that I know for sure what you're experiencing is a physical eyeball phenomenon. There are obviously other just as real events that look similar to the physical phenomenon, like those that unity100 shares here. Although the blue field phenomenon, if we want to call it that, can explain away what a whole lot of people think they're seeing, there are always those who will actually be seeing something else.
