keeps one's eyes open

Remains visually attentive

To keep one's eyes open is to remain watchful or alert, especially for something specific: Keep your eyes open for a gas station.

The phrase suggests vigilance without active searching—noticing opportunities or dangers as they arise rather than hunting for them.

I'll keep my eyes open for job postings.

Also *keep an eye out*.
