Eyes in pictures online?

Question

How can someone track you down by your eyes in pictures?

Answer 1

You don't know?!?

Along with the duct tape and plastic sheeting you should have around in case of a terrorist attack, you should also make sure that you remove your eyes from every picture of you.  Don't let anyone take a picture of you with your eyes open.  If you must post a picture of yourself online, use someone else's eyes in the picture.

Okay...seriously...they can't.  Dunno who told you they could, but the resolution of most pictures is just not good enough to do retinal identification with.  Unless, of course, you've taken a 3 megapixel shot of your eyeball and posted it on your website.

Answer 2

I don't think they can.
