i thought up of an interesting idea for NV, why didnt they include visible visors in first person? not enough time/didnt think about it/too much hud unseeable?

(i didnt create the mod, i just found the idea of visors interesting, and wondering if obsidian ever considered this.)
I had thought of soemthing like this, but instead of helmets, I was thinking if you wore sunglasses. It should darken the screen a little in 1st person.
