[2] LED lighting creates white light by combining blue light with other wavelengths ...
Glasses with a notch filter (e.g. EnChroma glasses) filter a narrow band of light around 590 nm that excites both the L- and M-cones (yellow-green wavelengths). They are often combined with an additional stopband in the short wavelength (blue) region to minimize the tint on the lenses and approximate a neutral-density filter. They improve on ...

Similarly, the blue light can often specifically be adjusted using the "night mode" of different operating ...
