The present invention provides a wavelength-selective transparent glass article which transmits light having a specific wavelength region having an effect of suppressing myopia, and has a low transmittance of ultraviolet rays having a wavelength shorter than the specific wavelength region, and is excellent in heat insulating properties. The present invention provides a wavelength-selective transparent glass article having a light transmittance T of more than 315 nm and a wavelength of 400 nm or less exceeding 315 nm and being 1% or more for 400 nm or less and a light transmittance T 315 having a wavelength of 315 nm or less. The wavelength below nm is 60% or less, and the solar transmittance by JIS-R3106 (1998) is 65% or less, and the solar heat acquisition rate is 0.70 or less. |
