This fantastic book by Edward De Bono makes a mention of the fact that the Chinese because of small eyes tend to have near sighted ness and hence a majority of them use spectacles.
Since the invention of spectacles dates back to only as late as the 14th century hence the author mentions that majority of plain & ordinary looking girls would have got married to such innocent Chinese because of their near sighted ness.
This explains the high Chinese population 😀😅
