The tall man's dark eyes took on a faraway look.

Her eyes took on a haunted look and I had to lean forward to hear what she was saying.

His eyes, as he looked at it, took on that gentleness she knew so well.

His eyes took on a wild look, and he lost a lot of weight.

For once, those odd eyes of his took on a bulge.

Her blue eyes took on life again, and heat.

He fell silent for a moment, and his eyes took on a haunted look.

Her dark eyes took on that cold, far look he remembered from their first encounters.

Her eyes at last took on a truly living look.

As she said it, her eyes took on that faraway look again.
