Clapton is saying that we live on through our children, generation after generation. He "knew" his father (finally) when he looked in his son's eyes and realized they were his father's eyes.
Clapton was raised by his grandparents, who he thought were his parents until he was in his teens. Growing up, he never knew his father, who only contacted him after Eric was famous. The sadness at not having a relationship is evident in this song.
In the lyric, "Just a toe rag on the run," "Toe Rag" is a slang term for a small child, street child, perhaps, in England.

Dougal from TexasI think people are missing the religious connotation in the song. His father's eyes are also God's eyes. Clapton has become very religious and this song can be looked at from that perspective.
Vincent Ferraro from Hesperia, CaClapton's father didn't contact him after he became famous, Clapton only found out who his dad was after the guy was already dead, in the 90's I think it was.
Maybe Steve from Long Island was thinking of John Lennon.
