> Higher frequencies need smaller holes to attenuate as effectively.

So let's make the holes smaller. We want to permit nanometer-wave light to pass while blocking centimeter-wave RF. I'm not seeing a particularly difficult engineering challenge here. :)

Did you think this through at all? Running away and hiding while wearing opaque aluminum foil blinders is kind of a unilateral non-starter.

Anyway, we also have this: Window film. Let's look at an example.

3M Thinsulate Climate Control 75 is a self-adhesive film that blocks greater than 99% of RF from 100MHz to 4.5GHz[1], which I might suggest is pretty good for protecting the ol' eyeballs from a brief encounter with the blindness machine.

The combination of it and a single pane of window glass provides 74% visible light transmission[2]. I further suggest that this allows plenty of light with which to safely move around.
