I love the black flame experiment works because of the sodium absorption and emission spectrums. Glassblower glasses make use of the absorption of Neodymium and Praseodymium to block the sodium glow when working glass.
EnChroma glasses work the way they claim to work. But whether they’re worth buying is another question.
