At 4m10s she shows the one I'm practicing the most now, training to focus. I like to do it one eye at a time, and then both. I don't aways use the thumb, I like to go to a park and do it between trees, when I'm on a bus I do it between the window's borders (because it's not transparent) and things out side.

Blink is very important to, try to remember to blink, so it's always lubricated enough. I tend to blink less when I'm on a computer, it's something I'm trying to work on.

I'll give it a few more months to see how it reflects on the eye doctor exam.
