Hello, I've been taught in high school that the most sensitive part of the human body was the index finger. However recently I've read that it is the clitoris... But I've a doubt if it is true. I'd like to know the sensitivity of the human eye. I don't have any anatomy book nor medical book. Wikipedia doesn't say anything about it... I'd be glad if you could tell me the eye' sensitivity. (of touch of course). Thank you.
