Well, if someone was to roll their eyes at you, you have a choice. You can either pocket their eyes, and leave them wandering around blind, or roll their eyes back again, so they can see again.

It's a joke, in other words. Here is the original joke:

Erste Person: Diese Frau rollte gerade ihre Augen an mir!
Zweite Person: Gut hatten Sie besseres, sie zurück zu rollen, sie konnten sie benötigen!
