I saw his eyes change but he looked down again quickly.

His gray eyes we cannot change, and so must risk.

Her eyes changed, and she looked very different, somehow real for the first time.

She is 15 years old and her eyes change color from green to brown to blue.

And then her eyes changed, as if she'd heard something I couldn't.

Her eyes changed so that they could see in the dark.

And I saw in a moment how her eyes changed forever.

The eyes hadn't changed much, though, and were still hard to look at.

His eyes changed color with every shift in the light.

It saw them; he could see the small dark eyes change focus.
