Hitomi

A second meaning of Hitomi is in its sounds like hitori. Which means one person. Many western people don't know Japanese has several groups of words for counting different items. Regular numbers are ichi, ni, San, shi/yon,go, etc. People are; hitori, hutari, san,yo, go-nin kimashita. So first-born would be named this often for basic reasons.

The word Hitomi is comprised of "hito," which means "person” (usually other persons) and "mi," which means "seeing, ” as when you look into someone’s eyes, you see an image of a small person - actually yourself. It is exactly the same etymology as the word pupil, which derives from the Latin word "pupa," meaning "doll." Both as a word and as a name, Hitomi is profound and beautiful.

I've never seen Hitomi written as "智美". However "仁美," with "仁" meaning benevolence, is very common, and so are "一美" and "ひと実" to a lesser degree. (with "実" meaning "truth" or "reality")

Please note that my kanji definitions are directly from the dictionary. I don't have any contextual experience with them, and I don't know Japanese.

In Japan, Hitomi is a very common name, and the definition, in its entirety, is "the pupil of the eyes". Obviously, this is a straight definition, and when translated into a more broad context, Hitomi usually means the reflection or the gaze (which is usually applied as "the beautiful gaze" or "brilliant reflection").
