What is the "eye" at the top of my phone???

All of a sudden I started seeing what "looks like" an eye (with the eyelashes, etc, LOL) at the top menu bar on the phone.  I've tried restarting the phone and when I drag down the "notifications" there isn't anything there that I can see that would relate to why this all of a sudden appeared.  Does anyone know what I am referring to and what it does/means/stands for/how to get rid of etc?

Thanks!
