PROBLEM TO BE SOLVED: To provide an anti-glare optical element having an anti-glare effect as well as maintaining visibility for a target object when the element is applied to outdoor spectacles or the like and the spectacles are worn during driving a car, walking or the like at night or in the evening and morning (particularly early morning).SOLUTION: The anti-glare optical element comprises a transparent substrate 10 made of an organic glass material. The organic glass material contains a pigment that absorbs a specified wavelength, and the transparent substrate 10 is dyed with a yellow dye. In a transmittance curve of the anti-glare optical element measured with a spectral photometer, an average transmittance in a blue wavelength region is decreased by dying the transparent substrate. At least one valley in a range from a yellow wavelength region to a red wavelength region, and at least one valley in a visible light upper limit region adjoining to the red wavelength region are formed in the transmittance curve by incorporating the pigment that absorbs a specified wavelength. |
