Hide damage indicators

Is there any command or any mod that allows you to hide the damage numbers?

They take too much screen and between that and the particles, cant even see the mobs.

 

I don't believe there's a mod to remove the damage indicators completely. However, what you can do is go into settings and turn down/off particle animations. This will help make the mobs more visible and also improve FPS (performance).

Another thing you could do is make your GUI scale to a smaller value, this would help with removing some of the screen clutter and make you feel much less tunnel-visioned.
