She's the Pepsi Girl with a whole lotta pop to her eyes. Van Graas is a supermodel, who also was the star of a great commercial for Pepsi's "Pop Culture" promotion. She walks through a crowd, taking tops off other people's Pepsis. The camera tracks her as she zeroes in on an unlikely-looking guy -- the one whose bottle top completes the winning phrase. Her powerful eyes convey the desired effect of targeting in on her destination.
Here's another example of eyes that look either blue, green, or some combination of the two, depending on which way and how much light is catching them at what angle. This cover shot for Glamour magazine makes them appear fairly green, although I suspect they're blue in most light. Try this trick: scroll up until all you see is from mid-nose on up. Her very symmetrical eyes resemble Shannen Doherty's, with that same pop, if you will.
