Abstract: Provided is a functional dyed spectacle lens obtained by dyeing at least one of the surfaces of an undyed plastic lens, characterized in that the density of the color formed by dyeing which is defined as a difference in luminous transmittance between the dyed lens and the plastic lens is 2-4% and the difference in average transmittance in the wavelength range of 530-570 nm between the dyed lens and the plastic lens is 3-5%.
