摘要

The optical material of the present invention contains one or more kinds of ultraviolet absorber (a) having a maximum absorption peak within a range of equal to or greater than 350 nm and equal to or less than 370 nm, in which a light transmittance of the optical material having a thickness of 2 mm satisfies the following characteristics (1) to (3),
(1) a light transmittance at a wavelength of 410 nm is equal to or less than 10%,
(2) a light transmittance at a wavelength of 420 nm is equal to or less than 70%, and
(3) a light transmittance at a wavelength of 440 nm is equal to or greater than 80%.
