英文翻译：单靠自己的眼睛无法看到自己的全身

最好意译：
You can never see yourself through (thoroughly) with only your own eyes.

It's impossible to see one's own body through his own eyes.

you can not see your entire body just with your eyes.

You can not see your whole body only with your eyes.

这才是翻译！
It is unable to see one's own whole body by one's own eyes only
