    Does this happen to anyone else, on a nice hot summers day when you look into the blue sky does anyone see like little spots moving? it looks rather like a kaliedoscope moving into itself no colour jut like shapes it never changes just the same pattern continously. I find it hard to explain, try staring into the blue sky and see if you notice anything moving.

    I have looked on the internet for some explanation as its only when i look into the blue sky that i see it? doe anyone have an explanation of what it is?

    I've seen it, too, but don't have a definite answer. One thing I know is that humans are not perfect, and neither is our vision. It could be just a glitch in the system that becomes visible when you're staring at a bright and very uniform surface (sky). It does appear to be internal, i.e. an optical illusion.

    After looking at your link there was this on the other searches which explains another of the things i've wondered about, and that is the little dots that fly around in the sky that remind me of little pond skaters when looking in the sky.

    Woo hoo one down now i just need to explain the patterns, the best i can explain it is if you look directly into a large area of blue sky for more than 3 - 4 minutes looking at the exact same place a sort of strange pattern emerges, moving from the outside into the middle of my vision and continually doing it until i look somewhere else.

    I will continue to think of a better way to describe it, or if you have blue sky there go try it.

    Cheer to both of you for posting, you were almost spot on there Mr m with the optical illusion and awesome you posted the wiki link Harold.

    It's eluded me for years and often wondered about what it is but never thought it would be explained but now i know

    Here's something I noticed just the other day. I look at a white sheet of paper and close my eyes. When I open my eyes I see the pattern of veins on my retina, or I suppose that's what it is. It looks like a map of the Amazon River and its tributaries or something. It only lasts for a fraction of a second and then I see a blank white sheet.

    I haven't noticed this i'll try it, but i always used to do the one where you push your eyelids against your eyes and you see the white noise take over your vision lol.

    it makes me think these optical illusion's our eyes play on us. I read that dogs can only see in black & white i'm not sure if its true but we'll use that as an example, to them the true world to them would be percieved as black & white where to us it's a whole different look and they can see perfect in the dark where our vision fails us. I wonder what it would be like looking through a pair of hawk or owl eyes their vision must be stunning and i'd say they see things totally different to us.

    It's quite amazing to think of the other walks of life and such a different point of view.
