I agree with the idea that focusing on life, rather than eyes, is
the most intuitive.  Then you can explain everything with a few
simple statements.

1) a group is captured if there are not empty spaces adjavcent to it.
2) a group is alive if no sequence of legal moves can capture it.

then you should simple examples of groups that are alive.  As a side
comment, you might mention that there are lots of unusual and tricky
cases, where the "rules" clause gets complicated - Starting with false
eyes, and sekis, bent four in the corner, and thousand year Ko.
