If you were comparing blurred to not blurred (and still not black), then okay. That would be a lower GPU load. It sounded like you were comparing blurred to black, which wouldn't be a lower GPU load.
As far as options, it is extremely unlikely that they would make it an option for black or not black. It'll be one or the other and you'll need a mod to change it.
It started with something WarMongerian posted about with visibility. I was a bit tired, to keep it short
and didn't proof on my pc like I usually do. Sorry the initial thought was muddled.
I take ownership of that, Morloc labeled it a long time ago R'lyehian, I use to confuse the Fudge out of Madmole.
Then it went from the thought basic sunglasses and the physical description of binoculars, to sunglasses and binoculars,
then to to sunglasses and binoculars and the individual Head armor appearances, it kind of took on a life of its own.

I always found it a bit odd when they added the 2 circles to the screen when someone in a tv show or movie used binoculars.
I agree, when I bend them down, its to align my eyes to see a single image. I was thinking that if I referred to often to the
NVG overlay the other potential addons would get lost in translation. Ironically the translation got lost in translation.
If it were possible I would like when wearing armor in first person for it to emu the view holes in the iron mask, with breathing
sound effects. Focal distortion and artifacts for the nerd, square overlays for the Nomad with sound and an opaque texture that
shows the inside of the dif head armors. But I figured that would be to much of an ask. The addition of the Cosmetic armor slot
made me think of visible overlay or straight view as an option plus tints. For optional immersion. To cover a larger group.
