keep an eye out
Be on lookout
To keep an eye out is to watch for something or stay alert to its possible appearance: Keep an eye out for the exit sign.
The phrase suggests passive vigilance rather than active searching—you continue other activities while remaining ready to notice what you're looking for.
Sometimes expanded to keep an eye out for trouble or keep your eyes peeled.
