I just did a little test with brightened and un-brightened paper. Frist, I
checked that the glasses do indeed mostly block a UV led flashlight, and
start to darken.
Then I checked the tint on both papers under fluorescent light with the
undarkened lens, and the tint was nearly equally visible to me.

If the paper was cheap, then this effect may be mostly the lens blocking the
UV that triggers the paper Fluorescent Whitening Agent.
