You don't need UV to stimulate florescence. 395nm blue light will cause yellow highlighters to light up quite brightly: https://par.nsf.gov/servlets/purl/10326338

UV-A starts from 400nm, so there is no "395nm blue light"

400nm by virtue of aggressive rounding. 395nm is well inside the visible range.

I'd love to see you provide proof that people can't perceive blue qualia from a 395nm EM exposure.
