The red lenses are to use under artificial lighting at night.
The yellow lenses are for computer glasses. They are to use while exposed to harmful fake light (most modern lightbulbs and screen technologies) during daytime.
Yellow (day): block an absorption curve of light ranging from 400 to 500 nanometers. The peak of this curve is 60% absorption at 455 nanometers.
Red (night): block all blue and the majority of green light frequencies, up to 550 nanometers.
Please do not use anti-blue light glasses in sunlight!
