In The Sun Song What Does Silver Sun Pickups' Song Lazy Eye Mean?

What does Silver Sun Pickups' song Lazy Eye mean? - in the sun song

I know what a lazy eye, but I can not be surprised if the song was written by Galileo Galilei. A portion of the bridge: "This is the room the sun and the sky" reminds me of Galileo. Not to mention Galileo had a lazy eye like no other.

I'm curious, what is the song really.
