1. A glazing for a vehicle, comprising:
a first glass sheet configured to form an exterior glazing of the vehicle with a first external main face and a second internal main face configured to be oriented toward a passenger compartment of the vehicle;
a lamination interlayer made of polymer material with a first main face oriented toward the second internal main face and with a second main face opposite to the first main face;
a second glass sheet configured to form an interior glazing of the vehicle with a third external main face oriented toward the second internal main face and a fourth internal main face oriented toward the passenger compartment,
wherein:
a traversing hole is arranged in a thickness of the lamination interlayer and in a thickness of the second glass sheet,
the first glass sheet comprises, on the second internal main face, an antireflective coating, that is antireflective at at least one working wavelength in the infrared in a range extending from 800 nm to 1800 nm, said antireflective coating being arranged at a bottom of the traversing hole and having a surface which is free and which faces an opening of the traversing hole,
the first glass sheet exhibits a content by weight of total iron oxide of at most 0.05%,
the second glass sheet exhibits a content by weight of total iron oxide of at least 0.4%, and
the antireflective coating is continuous across the entire bottom of the traversing hole and is arranged locally within the glazing, a periphery of the antireflective coating extending beyond a periphery of the traversing hole without overstepping beyond said periphery of the traversing hole by a distance of more than 100 mm, said periphery of the antireflective coating extending beyond the periphery of the traversing hole being arranged between the first glass sheet and the lamination interlayer.
