Their function is essentially the same.  Like cameras, eyes have a lens that helps focus the image and a receptor of the image, called film in cameras, we have a retina filled with nerve endings that detect light sends it over to our brain to get interpreted.

Your eye has a converging lens, so if you ever played with magnifing glass you know the effect of such lens. It concentrats all the light in one dot, which is on the back of the retina.

The dish antenna used for satellite communication.  The parabolic shape focuses the incoming signal onto a single point where it can be detected, amplified, and routed to the end user.\n\nA magnifying makeup mirror.  The shape causes light rays reflected off your face to strike the mirror and reflect off that mirror at a slightly different angle.  That particular reflection will strike your eyes in such a way as to make your face seem larger.  The larger it appears the easier it is to determine precisely where to apply makeup.  In addition, it can free a person from needing glasses to apply makeup, thus removing an obstruction to applying that makeup.

I kind of went through the same as you. I always plucked my eyebrows for no reason and eventually needed to use eyeliner in place of it. All I can say of what I did is start to focus on a new activity. It was when I was young, so what I did was study more. Get your mind on something else. Read a book, play video games, maybe try to do activities when you are using your hands so you can't pull them. Good Luck. Hope you pull through. :-)

In most cases, yes they will.  I have heard of some cases where they don't grow back, but that's unusual.  Being that it is uncommon, I still wouldn't risk it, I like my brows.
