I don't agree with higbal's theories as you might be overthinking it. To me "You better see right through that mother's eyes" just means "Don't be fooled by Paul's charm and pretty looks - see beyond it". i.e "I can see right through that motherf***er"
I also didn't initially buy into the LSD theory but when you read the quote from Macca via Barry Miles it does seem to fit very well. He even mentions looking into each others eyes and Lennon asking how he can sleep so there is a double meaning to both phrases. The "How Do you sleep" line also relating to Macca taking the others to court.
It also contains references that only those two would have understood at the time so would have made a real connection with Paul.
