I don't say they are eyes, but the anime was pretty close to the manga on this... personally I think they are "living creatures", (and so yes, they are eyes) because if it was a rock formation then I doubt nobody was aware of it until now (I mean it should on a map or react to the log pose). But I like how Oda left it in the mystery and I hope he will never clarify what they are, like an "eternal cliffhanger".
