We are often told that "God is watching us" as an ominous warning to behave ourselves. The truth is that God does watch us. However, God looks at us through the eyes of infinite love.
If you've ever been in love, you know that you become so fascinated by the object of your love, that it's sometimes hard to look away. You are captivated.
That's how it is with God. God loves us so much and we are so unique and fascinating to God that He can't take His eyes off of us! That's how love is!
