I've never tried it, but I did attempt to buy those color blind glasses (that are apparently just band pass filters) to see if they would make my landscapes more vivid.

Didymium filters have more effect on human vision than they do on most cameras. They filter out the yellow, near to the Sodium wavelength, and the narrow-band filters used in typical Bayer mosaics already have a gap there.

I have used a didymium filter a bit, but I was actually thinking something more similar to this:

https://enchroma.com

Which apparently is some sort of band pass filter. (Would didymium be a notch filter? I was never good at science.) If I remember correctly, the company started out when its creator noticed that microscopic imagining filters (or perhaps it was filters for viewing lasers) also enhanced color perception.

But this isn't exactly related to the OP's interest... in florescence primarily. So never mind; I think I'm after something slightly different (more perceived color saturation like with the "trichromatic back" using a color filter). But I'm curious about the OP's question, too.

I've been using didymium filters, and the variations "enhancers" blue, green, red, warming etc.  I like them.

I think they all have a notch in the orange, where they do pretty much the same thing that the enchroma glasses are doing.  Though there are other effects in the blue and green.
