Drop eye is caused by a high fat diet (usually pellets), that causes fat build up in the upper eye, making the fish look up isn't going to do anything.Tight fitting lid is a must, make sure it is secure or weighted down as well. Yes, it will jump. Not an if, but a when.
I fed mine pellets and the occasional market shrimp, grew like a weed.
Ive heard of people keeping something like a ping pong ball floating in the tank to prevent drop-eye, so maybe do some research into that.
Good luck!
