Try using a lot more light, that should result in a faster shutter speed and it will constrict your pupils to show more of the pretty blue irises. It takes a lot more light with a camera than your eyes need to look right.
On my bucket list is shooting some beautiful eyes with 4x5 color film, even if it is ~$5/shot, after scanning and sharpening the images are amazingly detailed. Blue x-ray film is cool with blue eyes also, really makes the irises shine almost white.

Great job holding that still while I closed the shutter, came out of the hood, inserted the film holder, and exposed the film!
I'm sorry my hosting site won't allow a bigger file 5 MB max, so you will have to hold down "Ctrl" and hit the "+" key several times to enlarge. The original crop is over 90 MB.
