Actually, it *does* slow down the light.  Sunglasses and other dark filters
are actually "red-shift" generators, and visible light passing through them
is shifted down below the visible range, and hence appears "darker".  The
literature is filled with stories of people who did not realize this, wore
ordinary sunglasses skiing, and wound up with severe burns due to the
now-infrared glare.
