PROBLEM TO BE SOLVED: To provide a wavelength selective transmissive glass article which transmits light in a specific wavelength range having an effect of suppressing myopia, has a low transmittance of ultraviolet rays having a wavelength shorter than the specific wavelength range, and is excellent in heat shielding property. A wavelength represented by the following formula 315nm ultra 400nm or less of the light transmittance T 315nm ultra 400nm or less is 1% or more, or less of the light transmittance wavelength 315nm of the following formula T 315nm or less 60% The following is a wavelength selective transmissive glass article having a solar radiation transmittance of 65% or less defined by JIS-R3106 (1998) and a solar heat gain coefficient of 0.70 or less.
