Looking at the diagrams [1], I see that it works by creating 3 pass-bands. I understand how it would work for natural light. But how well does it work for you with CRT/LCD monitors that simulate the color gamut using just the three primary colors? Do these glasses help you with monitors too? How well do you discern color on monitors with/without these glasses?
