I know "as far as the eye can/could see" is an idiom, which means "for a long distance until something is so far away and small it cannot be seen any more", but why is it "eye" instead of "eyes"? Thank you!

It is the same sort of generalised usage as in "the pen is mightier than the sword", and it does not refer to any specific eye. A pair of eyes can see no further than a single eye can, so it is not necessary to suggest there is need for more than one eye.

  • Thank you all for your responses! Now I understand why 👍👍👍
