Glass article

A glass article, comprising:

• a glass substrate;
• and an antireflection film provided on at least one surface of the glass substrate, wherein:
• the glass substrate absorbs light at a wavelength of 250 to 400 nm which is incident from the surface;
• and
• the glass article has an ultraviolet irradiation degradation degree (X) of 1.5% or less,
• wherein the ultraviolet irradiation degradation degree (X) is T0−T1, where T0 is an average transmittance of light at the wavelength of 250 to 400 nm which is incident from a surface of the antireflection film of the glass article in an initial state, and T1 is an average transmittance of light at the wavelength of 250 to 400 nm which is incident from the surface of the antireflection film of the glass article after irradiating the surface of the antireflection film with ultraviolet rays for one hour by using a 400 W high-pressure mercury lamp with a main wavelength of 253.7 nm facing the surface of the antireflection film of the glass article at a distance of 20 cm.
