These are helpful references, infinity10.

I do have one question, though.

How is #4 ref. photo, different from #5 photo, excluding the obvious that #4 is a photo of an Asian eye, and #5 is of a Caucasian? They look about the same to me.  

Other than calling the Asian one 'epicanthic' and the Caucasian one, 'deep-set', I don't see a difference.

I'm not trying to be difficult or hard to get along with...they both look the same to me!

 

Is there an actual, physical difference that isn't apparent here?
