They claim that the human eye is protected by the cornea
which acts as a filter. I wonder if they could add such
a protection filter (against LIDAR lasers) to digital
cameras.

I'm still not convinced. So it absorbs the IR before it hits the retina, what's the effect of rapid heating on the cornea? Any IR filter strong enough to screen-out a high-power laser hit will make the camera unusable.

Why would that be? IR is not a range that is normally included in
photographs, so having a removable filter would be a good thing. If
someone was intent on taking IR images, just remove the filter and stop
shooting self-driving cars.

if you believe that the cornea acts as a filter, aim a laser into your
eye and report back, or have someone else do so, since you won't be
able to.

cameras already have an ir cut filter.
