I see the haze with and without glasses - so do my students. If I had to
guess, looking at the orange directly overwhelms the very faint
perception of color. I wonder if all of us perceive a UV source the
same.

Why is the purple haze *around* the orange instead of coincident with it?
My first impression was that only those with glasses would be able to see
the purple haze (due to dispersion through the glasses) but I had assumed
the colors would be coincident.

others cannot. I think this maybe the result of being able to perceivecolor deeper
into the UV.
