- To have an Eagle Eye is someone that has the ability to see important detail.
- To turn a blind eye is to pretend not to see.
- “It’s all fun and games ‘til someone loses an eye.” This comes from ancient Rome, as the only rule for their bloody wrestling matches was to have no eye gauging.
- Keeping an eye peeled is to keep watch for something.
- Having eyes in the back of one’s head is to know what is going on even when one cannot physically see it.
