I'm saying it doesn't take much of an eye to tell the difference between a Korean and a Japanese, yes. Or to tell the difference between a Iranian and an Indian, come to that.
Them's the facts. I can tell you don't like it that that's the way things are, but there you go.
"Them's the facts"?
O rly?
Well in that case yiou will find it very easy to back up your "facts".

The "average" Iranian:
"While a categorization of a 'Persian' ethnic group persists in the West, Persians have generally been a pan-national group often comprising regional peoples who rarely refer to themselves as 'Persians' and sometimes use the term 'Iranian' instead. The synonymous usage of Iranian and Persian persisted over the centuries despite the varied meanings of Iranian, which includes different but related languages and ethnic groups. As a pan-national group, defining Persians as an ethnic group, at least in terms used in the West, is problematic since Persians are a varied group."
"According to the CIA World Factbook, Iran's ethnic groups consist of: Persians 55%, Azeris 24%, Gilakis and Mazandaranis 8%, Kurds 7%, Arabs 3%, Lurs 2%, Baloch 2%, Turkmen 2%, other 1%..."
"...the Iranian people include not only the Persians and Tajiks (or eastern Persians) of Iran, Afghanistan, Pakistan and Tajikistan, but also the Pashtuns, Baloch (Pakistan), Kurds, Lurs, Zazas, Ossetians and others..."

The "average" Indian:
India's population of approximately 1.15 billion people (estimate for July, 2008) comprises approximately one-sixth of the world's population. India has more than two thousand ethnic groups.
Unlike the United States, United Kingdom, and Australian Censuses, the national Census of India does not recognize racial or ethnic groups within India... It should be noted that Indo-Aryan, Dravidian, Tibeto-Burman and Austro-Asiatic are mainly linguistic terms and denote speakers of these linguistic groups.

"A Parsi is a member of the larger of the two Zoroastrian communities of the Indian subcontinent. According to tradition, the present-day Parsis descend from a group of Iranian Zoroastrians who emigrated to Western India over 1,000 years ago. The long presence in the region distinguishes the Parsis from the Iranis, who are more recent arrivals, and who represent the smaller of the two Indian-Zoroastrian communities."

So how does this having 'much of an eye' work exactly then?
Are you saying that you have a stereotype of "an Iranian" and "an Indian", and in your imagination the two are different, or are you making some kind of bizarre claim that there is a clear visual criteria from separating an Iranian (whatever you mean by that?) from an Indian?
I could repeat that paragraph with 'Korean' and 'Japanese' as well.
You couldn't really have picked two worse examples frankly. You would have a much easier time arguing that it is easier to visually identify a Nigerian and a Swede for example, but for some reason you have chosen examples where there are vast amounts of "overlap" and where the differences are language and culture rather than phenotype (eg Japan -v- Korea).
