You close your eyes, and press the eyelids. Don't press too hard. It shouldn't be painful. Over time you can press harder as the eyes get healthier.
Watering eyes is probably normal, but I think it will subside over time.
I love that set of qigong. It is similar in ways to the eight brocades, but all exercises I've never seen before.
I had a lot of fun filming that program with Grandmaster Kao.
