Women go crazy for the big blue eye. Tom Waits, Eyeball Kid
Heres an interesting analysis of the Doctor Who finale. I hadnt thought before of these past two seasons being bookended by gigantic eyeballs with opposite meanings. (Come on, by itself thats not much of a spoiler.)
I could add that the past two seasons have been obsessed with eyes and vision even more strongly than the review mentions. Weeping Angels, the Silence, and the eyepatches are the most obvious cases. (And remember the Angel in Amys eye.) Then there have been all the uses of perception filters and psychic paper … and Van Goghs vision that enables him to see blind (!) monsters and exploding TARDISes invisible to others ….
