What Lense Should I Use if I'm Nearsighted?

unfortunately my vission is far from from perfect. It was probably from all of those books I read as a child that messed my eyes up but thats not important for now. I have nearsighted vision where i can see things that are close to me but not far. I was wondering what lenses are the most helpful converging or diverging lens. i found out its the diverging lens thats best suited for the job. It is because when i use diverging lenses it helps me focus images from a farther distance
