How To Grow Back Eyelashes?

So like 2 weeks ago, i was putting on my mascara before school and i used an eyelash curler to curl them. But when i took the curler off i noticed that the inner part of my right eye had no eyelashes. Im very concerned that they will not grow back. I was wondering if they do grow back? If so, how long will it take, and is there anything i can do to help them grow back?
