Is it possible to took at the "lens" of your eyes?

    Sort of, but not in the way you are describing.

    The lens is transparent, designed as such,... and while what we see goes directly through it, we see it just as much as we do our corneas. Now if you have a disease or problem that clouds the lens, ie: Cataracts -- you would be able to see the lens much better as it would have a coating on it.

    Our eyes are in constant motion.. literally -- they have to move slightly ever few microseconds to 'maintain' a clear image. If we were to LOCK our eyes in one spot and not move them (if that were possible) the image would fade away. Our receptors need constant stimulation.

    I'm not sure what you are seeing.. but I'm sure it is natural phenomenon -- It could be anything from starbursts, halo's.. or just 'focusing' and seeing things for the sum of their parts instead of the whole at once. (Make sense?)

    It could also be similar to the 'Visual Snow' phenomenon where many people see flickering 'grainy' type of particles in their vision among other odd abnormalities that have yet to be explained. Neurologists are working on it though. :)

    You cannot see your retina.. it is just the receptor, what allows you to 'see'.. to send input down the optic nerve. No, you cannot see individual photons, as they move much too fast.

    I do know what you are talking about, but it is a hard phenomena to explain.

    No.

    You cannot see your OWN lens, or retina, or what have you. However, an eye doctor (optometrist) with the correct equipment can. There are also many new instruments now that can take many different types of photographs including photos of your retina, optic nerve head, and even some can image the layers of cells in your retina.

    The only time you may be able to see your own lens is if you have a very dense/thick cataract in one eye only, you may notice the area behind your pupil looks white-ish if you look in the mirror And I say one eye only because if you have dense cataracts in BOTH eyes, you won't really be able to see anything! You'll need at least one good eye.

    Some people notice floaters, especially when snow skiiing or looking at a white sheet of paper. These are actually vitreal floaters and are little groups of cells that are floating in the back of your eye, near the retina. They are just left over from development and are of no concern at all, which these are much different from a retinal detachment (which is serious).

    Otherwise, no. You cannot see anything in your own eye.

    And if you are curious, there are no "photons" inside the eye. What captures the light and sends the images to your brain to process, are called photoreceptors. They are so small that they can only be imaged with scanning electron microscopes on dead samples (you can't get one of those into someone's living eye), but you can see the layer on a machine called an OCT
