    Hard to say what the largest thing i've seen with my own eyes is. Probably one of the stars in the night sky. As for smallest. The film of a soap bubble is pretty thin, although the bubble itself is fairly large in all.

    The smallest thing I have seen with my eyes is probably dust. The biggest thing I've ever seen is every thing I look at when I see the sky.

    Once when I was little, my family went to this event at an observatory where you could look through the big telescope- I was hoping to see Saturn or something that looked really cool close up, but instead they showed us this galaxy in the constellation of Orion that was extremely huge and extremely far away- cool in theory, but you basically had to squint until you could see a little white smudge. It was pretty neat to think about, but I still would have liked to see saturn, hah!

    The largest object i have observed with my own eyes (under the category: human body) is the heart.

    The smallest object I have observed with my own eyes was a plant cell

    Perhaps the smallest object I have observed with my own eyes are the "floaters" within my eyes. These flecks and cobwebs float around in the fluid. They cast shadows on the world around me.

    The largest thing i have seen with my own eyes is a portion of the universe. The smallest thing i have seen with my eyes is a speck of dust (if assuming the question didn't me with the aid of a microscope or pictures of thing taken with really powerful microscopes).

    The largest object i've ever saw with my naked eyes is probably the moon. Despite looking small i know it's actually huge.

    The smalest object was sand. That or my gramma's patience :)

    The biggest thing i have ever seen is probably a star. The smallest is some particles from a fish scale i saw through a microscope.
