Jay is on the hunt for some sex-starved ice-cream lady

JAY: Nah, if she put on a bit of fake tan and slipped into some sexy undies I’d definitely give it a go. It must be her, I’ve given everyone else the eye.

SIMON: She looks like she could give you her actual eye.

I know "give someone the eye" means to look at someone in a way that shows you are sexually attracted to them, but what does "actual eye" mean here?
