Close, blue contacts when on duty.
"Hey, you look like raging hard-on"
"nope, see, my eyes are the wrong color"
"I see"
The perfect plan.
EDIT- However an eye patch when not working would also probably work well. The one eyed guy would never be suspected as secretly having both eyes. Or I could pretend to be blind or asian.
I'll just have to wait and see.
Penis, away!
