Make VISOR goggles protect the wearer from the wizard's blind spell

[Faceplant]

Just what the title says. I tried wearing VISOR goggles to counter the blind spell, and while the goggles did prevent me from going completely blind, I was pretty much still incapable of seeing what the hell was going on. The VISOR goggles shouldn't be a perfect counter to the blind spell, but they should negate most of the harmful effects.

Alternatively: Being blinded while wearing the VISOR goggles permanently gives the goggles a color filter. Further hits from the blind spell makes the filter less transparent, until the goggles are worthless.
