Here's another excerpt from the American Pregnancy Association:

Weeks 9 thru 13 - Gestational Age (Fetal Age - Weeks 7 thru 11):
The fetus has grown to about 3 inches in length and weighs about an ounce. The genitalia have clearly formed into male or female, but still could not be seen clearly on an ultrasound. The eyelids close and will not reopen until the 28th week of pregnancy. The fetus can make a fist, and the buds for baby teeth appear. The head is nearly half the size of the entire fetus.

And here is one from babycenter.org

By week 28, your baby weighs a little over 1 kilogram and may measure 38 centimetres from top to toe. At about this time, your baby can open his eyes and turn his head in utero if he notices a continuous, bright light shining from the outside. His fat layers are forming and his fingernails appear.

So it looks like I was wrong after all - I had it too early. They don't open their eyes until around week 28.
