While I am in the camp that believes camera-only FSD won't succeed, your comment isn't entirely accurate.

CCD and CMOS sensors can easily work in sub-freezing temperatures with various kinds of heating. There are 10's of millions of surveillance cameras installed outdoors in sub-freezing climates that work fine.

Cameras also have moveable IR cut filters, which is analogous to your sunglasses example.

Human eyes do have greater dynamic range in the visible light spectrum, but solid state sensors can commonly interpret light above 1000nm, and of course you can do thermal/IR imagers to provide optical sensing of wavelengths outside of what a human can see.

Sensor technology relative to the human eye isn't what is holding FSD back.
