## Definition

the whole round part of your eye. In casual talk, people also use this word to mean the number of people watching a video or looking at a website.

For teachers: the entire ball-shaped part of the eye, including the parts hidden by the socket. In informal or marketing contexts, it refers to a person viewing a specific piece of media or advertisement.

## Examples

- The doctor checked my eyeball for any signs of redness.
- The marketing team is focused on getting more eyeballs on their new social media campaign this month.
- While the anatomical structure of the eyeball is remarkably complex, the digital economy treats it as a simple unit of attention to be bought and sold by advertisers.
